Your Cinnamon Roll & Morning Coffee: Powered by Oracle Enterprise Manager

Truth be told, as I was getting my morning coffee today, I was pondering the recent election results more than Oracle [there, I said it]. But then an email from Glen Hawkins from the Enterprise Management team hit my Inbox and I started viewing this video. It was about the world’s largest convenience store chain, 7-Eleven, focusing on creating the best Digital Guest Experience (DGE) for their customers. Turns out that Oracle Enterprise Manager (OEM) powers 7-Eleven’s DGE Middleware Platform as a Service solution that consists of Oracle SOA Suite, Exalogic, and Exadata. “We need to present a consistent view of 7-Eleven across all our endpoints: 10,000 stores & various digital entities like our websites and apps”, said Ronald Clanton, the DGE Program Director for 7-Eleven. As 7-Eleven was rolling out a loyalty program with mobile support across multiple geos, it had many complex business & technical requirements, including supporting a wide variety of different apps, 10M guests in NA alone, ability to support high speed transactions, and very aggressive timelines. A key requirement was shortening the cycle for provisioning new environments. Whereas with other vendors this would take a few weeks, Oracle consulting showed them how with OEM provisioning new environments would take half a day, which was quite impressive. 7-Eleven has started to roll out this new program and are delighted to report that some provisioning cycles are as low as 10 minutes which includes provisioning the full Oracle SOA suite, Exalogic and more. They are delighted with OEM’s reporting capabilities and customization thereof. Watch the video to see for yourself.

Replay and slide PDF is available at the same URL you used to visit the webcast originally

Q: what does "C" stand for in 12c?

It stands for “Cloud”

Where can I get details on the new features?

See the OTN Documentation online, join the monthly webcasts and the OTN Virtual Developer Day

when will the training for weblogic 12c be available in oracle university

Oracle University currently offers comprehensive training for WebLogic Server administrators as well as developers now using WebLogic Server 12c to develop and deploy Java EE 6 applications.  Many of the core administrative features available with Oracle WebLogic 12c are unchanged so our Oracle WebLogic Server 11g administration courses are still suitable for Oracle WebLogic 12c administrators.  We will be updating these administration courses in early 2012 to include appendices that specifically address the new features available with the 12c release, but the core course content is applicable for 12c and 11g users.  Additionally, for developers using Oracle WebLogic 12c, Oracle University offers a expansive set of Java EE 6 developer courses and certifications covering enterprise application development with EJB, JPA, Web Services, JSP and Servlet technologies.

How does 12c compare to 11g?

There are over 200 new features in 12c, but generally speaking: deployment/management, developer productivity, and the perennial focus of performance, reliability, availability, and scalability.

How to engage in the WLS certification program? where to get the certification test suite?

If this question relates to an ISV Application for WebLogic Certification, the best vehicle to achieve this is through the “Oracle WebLogic Ready” Program, part of Oracle Partner Network (OPN). ISV Applications are tested and certified by the vendor themselves, based on their own appropriate testing procedures unique to their application(s). The ISV partner provides an active URL which describes your application and verifies that your application is generally commercially available to commercial customers and works with the latest major release or version of the applicable Oracle Exastack Ready software program (e.g. latest release of WebLogic). For Individual consultant and company certification for WLS, please see the OPN Specialized Program applicable to WebLogic for SI criteria.

What is available to us novices to help learn your products?

Oracle University provides training classes. Also, we provide a full documentation set and there are blogs and forums on There are also Oracle User Groups in many cities around the world.

Certifications, Platform support, Licensing

Oracle after the purchasing of Sun, is going to put licenses on Java?

No. The only licenses are for support (Java for Business, etc) or for J2ME licensees

Do we have to pay extra to avail of Oracle Virtual Assembly Builder?

Oracle Virtual Assembly Builder and WL Suite include Oracle Virtaul Assembly Builder

If we have a license for an earlier verion of weblogic, can we upgrade to 12c?

As long as you are paying support/ maintenance on your existing WebLogic license, you have full entitlement to upgrade.

What platforms with 12c are available on next week? Solaris? Windows? Linux?

Yes -- WebLogic 12c will be available on Solaris, Linux, and Windows at GA. For a full list of supported OS's please review the WebLogic 12c datasheet available on

Has there been any change to the Active Gridlink for RAC licensing in 12c such that it no longer requires an Exalogic license to use?

Active GridLink is licensed via WebLogic Suite which does not require Exalogic.

Do I need a license for using ADF? Even if i use another application server?

ADF is licensed separately for non-WebLogic servers, but it is included in every WebLogic Server license.

Which OSB version will fit WLS 10.3.6?


Will Oracle describe the pricing/licensing model for using

Currently Oracle has not published a pricing model for As you know the intent is for it to be subscription based model but no prices have been published yet.

Will licensing for WebLogic 12c change compared with Weblogic 11g?

No, it will stay the same

How much does an exalogic elastic cloud cost?

There are various packages and price points. Best bet is to contact your sales rep.

No announced plans at the moment, but generally WebLogic Server 12c is the first of the Fusion Middleware to release, followed by the rest of Oracle portfolio in CY2012 / CY2013. Currently Enterprise Manager is the only other Oracle FMW product that is designed to work with WebLogic 12c as of Dec 2011.

Is existing FWM products ( certified for WLS 12c?

No FMW 12c products will be certed on WLS 12c beginning next year

Does EM need an extra plug-in to support the management of WLS12c? Is there e.g. an application server plug-in necessary?

No. Thanks for asking.

Can you install FMW on Weblogic 12c?

Fusion Middleware 12 will be released across CY2012/2013, with some products released earlier than others.

Does 12c support Porlet jsr-286 and wsrp 2.0?

Both WSRP 1.0 (JSR-168), WSRP 2.0, are supported by the Oracle WebCenter product.

does GridControl 12c works on weblogic 12c

Yes, EM 12c will support WebLogic Server 12c. The EM team is currently doing the certification.

Is there any improvement in wls 12c for integration with tuxedo systems?

There are no particular features done in this area.

Will WLS become E-Business Suite's internal technology stack replacing OC4J and jServ? Any schedule?

Yes - EBS 12.2 is planned to use WebLogic.


Will WLS 12c support OAUTH 2.0 to implement authorization constraints for RESTful web services?

No. Thanks for asking.

FIPS 140-2 validated cryptography enforcable? Which certification applies to this?

FIPS 140-2 support will be provided through new RSA libs

What about security?

SSL support has been upgraded in WLS 12c to support TLS 1.2. Also new support for cert validation protocols like OCSP

TLS 1.1 or 1.2 supported?


What kind of security features have you included in Weblogic 12c, now that it supports cloud, do you have any add-ons

TLS 1.2 support and support for new cert validation protocols like OCSP

Have there been any improvements/changes to built-in authentication providers (negotiate) in WLS?

No change to providers per se

JDE BSSV is supported with WLS 12c

Not yet.

What is the NIST issued FIPS 140-2 validation certificate number that applies to the "new RSA libs" that providet the cryptography for this implementation?

WLS does not have a FIPS 140-2 certification, but we bundle FIPS 140-2 certified RSA Crypto-J library. It's 1047 as given at

We are required to test "secure configuration" of applications. Is there a provided "secure configuration checklist" or testing tool for developed Weblogic server applications?

In the standard documentation, there is a set of explicit guidance for "locking down" a production environment.

Is the crypto acceleration available only with Intel-based systems, in general, or specific to engineered systems like Exalogic? Oracle Traffic Director crypto acceleration features are in the context of the X86-based Exalogic systems.

IDE / Tools / ADF

Which IDEs can I use with WebLogic 12c right at GA?

OEPE 12c and NetBeans 7.1 will support WebLogic 12c right at GA. JDeveloper will be supported on WLS 12c in a minor version release in CY2012.

Is JDeveloper or NetBeans or Eclipse the IDE of choice at Oracle?

OEPE and NetBeans are both supported on WLS 12c, and is your choice on which to use. JDeveloper remains the strategic IDE for FMW, and will be supported on WLS 12c in CY2012.

If we use the ADF framework for forms and reports transition on weblogic, are we locked in proprietary code?

No you will not be locked in. ADF is a Java EE framework and runs on multiple servers. Of course it runs in a highly optimized fashion on WebLogic Server. Forms and Reports are available on Fusion Middleware 11g and have been carried forward from many previous releases of Forms and Reports.

Can I use ADF and or JHeadstart with WebLogic 12c?

WebLogic doesn't yet support ADF/JDEV, but will sometime in CY2012

Can ADF use JEE6 features like Bean validation and CDI? As well as JSF2?

JDeveloper 12 will to support CDI, and since ADF Faces are just regular JSF components you should be able to use them with CDI.

That being said, the main binding technology we use in ADF is still ADF Binding and not CDI, and right now there are no plans to change this. Note: ADF doesn't yet run on WebLogic 12c. Oracle plans to release JDEV / ADF support sometime in CY12.

Are there going to be changes to Oracle ADF with the WebLogic 12c support of EE6/Facelets?

ADF Faces components are already Java Server Faces 2.0 compliant... whether a given component uses facelets internally in on a component by component basis. Has little to do with WebLogic 12c, more about ADF runtime.

Is this NetBeans direct deployment available for Production mode as well?


Is NetBeans 7.1 going to support remote deployment of applications in wls 12c?

Remote debug to WebLogic 12c is not yet supported, sorry! It's in plan I believe, please check netbeans wiki

Can we also get some more idea on Mobile development capabilities around 12c release? Will it support iOS / Android?

The upcoming release of ADF Mobile will most definitely support iOS and Android.

Check out: <a href='' target='_blank'></a>

Will JDev also support WLS 12c as its integrated wls?

JDeveloper will support WebLogic Server 12c. Formal certification will be during 2012. OEPE and Netbeans will support WebLogic Server 12c immediately upon release.

Any circumstances where Eclipse is only choice for development?

Oracle coherence development tools.

Will eclipse have also integrated support for in deep wls development, debugging and deployment like JDeveloper have?

Oracle Enterprise pack for Eclipse does have deep, integrated debugging support with WebLogic Server 12c. OEPE does support ADF Faces & TaskFlow, through ADF runtime itself will not be immediately certified on WLS 12c. ADF will be supported on WLS 12c in CY2102

Will ADF work with java EE 6?

ADF/JDEV will support WebLogic 12c and Java EE6 sometime in CY2012. ADF already supports some aspects of Java EE6 (e.g. JSF 2.0)

Are there any plans to offer IntelliJ support in addition to Eclipse, Netbeans, etc

IntelliJ has always done a good job supporting WLS, but since JetBrains is a different company, we can't comment intelligently on their timelines.


What is ExaLogic?

Oracle Exalogic Elastic Cloud, the world‘s first and only engineered system for cloud computing. Oracle Exalogic Elastic Cloud is, tested and tuned by Oracle to provide the best foundation for Java applications, Oracle applications and other enterprise applications and it has significant performance gains.

What is engineering systems and conventional systems? Examples...

Exalogic and Exadata are examples of engineered systems. They are engineered for a specific purpose. Conventional systems are architectures that you would build yourself with various storage, computer and networking hardware.

Private cloud is supported only on exalogic? or oracle VM? or now it is also supported on VMWARE for example?

Oracle is unique in that its cloud offering is available in conventional environments, on Exalogic and in the Public Cloud. WebLogic Server 12c will most definitely work on VMware. WebLogic is independent of the underlying virtualization technology.

true that Oracle Public Cloud will not support EJBs nor JMS at the beginning?

Oracle Public Cloud does support EJB initially and JMS is on the roadmap.

How do I access Public cloud applications for learning

You can go to and ask to be notified when Public Access is available. Please register - we are very excited for your feedback.

Does OVAB support Apache web server?

At present, OVAB only supports introspection of Oracle HTTP Server (OHS), although it is possible to define generic Apache as an external component of assemblies

Does OVAB currently supported in Weblogic 12c and for production use?

The OVAB plug-in for WebLogic 12c will not be available at GA: we are currently working to update the plug-in and will release this at a later time

How is 12c integrated with exalogic?

WebLogic Server 12c will be certified with Exalogic at GA, and there are additional optimizations implemented in WLS 12c for Exalogic.

Is there any plan to support 12c on non-oracle VM infrastructure?

Please refer to My Oracle Support note #249212.1 for full details of Oracle's support policy on VMware and other 3rd party hypervisor technologies.

Will there be a virtual Exalogic platform for development environments? For those of us developing for deployment on disconnected networks, this could be useful.

The virtual environment - OVAB, OVM with WebLogic Server - can be run locally independent of Exalogic. There are further optimizations around manageability and administration that are specific to Exalogic but those tend to be deployment oriented versus developer oriented.

OVAB and OTD can be installed on any server or only Exalogic?

We currently only plan to support OTD for the Exalogic platform. OVAB supports Oracle Linux and OVM 2.2

Can Virtual Assemblies support products outside the Oracle product family, e.g. Apache Web Servers? Can I add support for additional products that are not natively supported?

Oracle is working to provide integration points with Oracle software. For things that are not provided by Oracle there is an SDK so you can write your own plugin if you would like.

Are there any plans to support non-OVM virtualization platforms with OVAB yet?

Not at this time

Will WebLogic 12c have optimizations to run faster on Exalogic via the Exalogic cloud software?

Yes, WebLogic has a number of enhancements specific to the Exalogic environment.

Will support ADF? Currently only JEE apps are supported. Will the ADF runtime be deployed?

Yes will support ADF applications and Java EE applications.

Does Virtual Assembly Builder work with other app servers, say jBoss?

Not for introspection, but you can define assemblies that work with jBoss as an external component

if I have understood the new weblogic server 12 c allow to make public and private cloud

Yes - WebLogic is the foundation of the enterprise Java cloud strategy and can be used to build both private and public clouds.

So does that mean that 12c will not work on VMWARE?

12c would most definitely work on VMWare. WebLogic is independent of the underlying virtualization technology.

Will virtualization support include WebLogic installation on VM instances to improve "ready for use time?"

You can deploy custom OVM templates with WebLogic Server pre-installed, ready to be configured using WLST or the Admin Console; you can also use Oracle Virtual Assembly Builder to build compete virtual application assemblies, which can be deployed ready-to-run based on a pre-tested master configuration.

Will an OVS template be available for the WLS 12 download?

We are not planning to release pre-built OVM templates: however, it is straightforward to create a custom OVM template, based on a standard WLS install

Can Virtual Assembly Builder be use to roll out images on the Amazon cloud?

Not at this time

OTD is a replacement for OHS on Exalogic?

OTD provides HTTP/1.1 caching/reverse-proxy capabilities optimized for Exalogic and FMW. OTD does not currently support static content (classic web server) functionality - however it can be used a superior alternative to OHS/plug-ins

Is Oracle Application available on cloud computing?

Yes some Oracle apps are like CRM. For a list of all applications please visit

Do I have to have subscribe for cloud or you can provide a test cloud space? For eg: like pointbase Thanks for your question. You will need to subscribe to it when it's available.
Does oracle cloud provide CDP capability, virtual data centers (VDC), VDC failover /fail back features No, we don’t offer any of these features for our tenants to access directly, though those that relate to DR, failover, and recovery are roadmapped for a future release.

Is development to oracle cloud free for development?

WebLogic Server can be downloaded for free trial from Oracle Technology Network. In the public cloud there is planned to be a free trial capability as well.

Traffic Director/RAC/Gridlink

Are there any plans to support Universal Connection Pool (UCP)?

Thanks for asking. WebLogic uses UCP RAC module for Active GridLink implementation.

Will there be tighter integration with the apache mod_proxy for load balancing views, reporting, debugging?

We supply WebLogic-specific reverse proxy plug-ins for Apache (<a href='' target='_blank'></a>) For Oracle Exalogic, Traffic Director will provide significant performance and availability boosts.

What is a Traffic Director?

Traffic Director provides highly-available caching, reverse-proxy and load-balancing services optimized for Exalogic and Fusion Middleware

Is there any improved load balancing functionality (additional LBR algorithms) in 12c Plugin?

No the LB algorithms in the plug-ins have not changed: OTD (Traffic Director) provides additional LB options

Is Traffic Director to replace Node Manager?

No: Node Manager is used to control the lifecycle of WebLogic Server and Coherence instances

what is traffic shaping in OTD

OTD provides capabilities to manage QoS based on the content of incoming requests: this can be configured on the basis of max connection, rate etc.

Is traffic director is a mechanism ??? or an application ?? in exalogic

Traffic director is a separate product that runs on Exalogic to provide highly-available, high-performance reverse-proxy/caching/load-balancing for Java EE and FMW applications: optimized for Exalogic

Can Traffic Director be used with legacy WebLogic implementation to replace say Apache WebLogic Plug-in?

Please check the certification matrices for details of WebLogic Server version supported with Traffic Director. This information will be available via the Oracle Technology Network when Traffic Director is released.

Can I download OTD to a non-EL server and fiddle with it to learn, will it work ( like OHS, webCache etc) on non-EL servers ?

Yes, OTD will be downloadable from Oracle Technology Network and it can be run on an appropriate 64-bit Oracle Linux install (for example using Virtual Box). However, it will only be *supported* on Exalogic.

Is compression supported by OTD?

Yes, we support HTTP compression and hardware assisted compression is available via the Intel Integrated Performance Primitives (IPP) libs on Exalogic - this can deliver significant performance boosts in given scenarios

is there some white paper and or documentation we could review prior to announcement of Traffic Director

Yes, you could start with the Oracle Traffic Director datasheet that will be available shortly on on the RHS portlet. When the product is available for download the documentation will be available as well.

Will OTD (Traffic Director) replace Coherence as it suports caching and scalability?

No. these products address different scenarios. OTD provides HTTP/1.1 caching, whereas Coherence provides high-performance caching of application-level objects and data

Does OTD also replace the Coherence proxy servers?

Not at this time, coherence proxies are not for HTTP proxying, they are specific to coherence.

Looks like OTD is used exclusively on ExaLogic to replace the need of OHS, webcache etc, to address the limitations of the webtier on Exalogic version 1; so OTD is kind of “ExaWeb”, is that correct.

Yes: OTD on Exalogic provides significantly enhanced functionality over and above that offered by OHS/WebCache.

How traffic director provide HA?

OTD uses VRRP (Virtual Router Redundancy Protocol) to support highly-available virtual IP listeners. The Exalogic Base Image will provide VRRP service via the keepalived RPM

Is Oracle Traffic director is similar to Dynamic Routing Architecture from Sonic?

I am not familiar with Sonic's Dynamic Routing Architecture: OTD provides highly-available caching, reverse-proxy and load-balancing for HTTP/1.1 traffic optimized for Exalogic and Fusion Middleware

What use cases would Oracle advise re: using OTD vs. an external load balancer?

For all Fusion Middleware or Application deployments to Exalogic, OTD will typically provide better performance and much richer functionality than an external load balancer.  You will also benefit from Exalogic-specific hardware optimizations and native Infiniband networking support.

Will Traffic Director also provide load balancing and the web tier functionalities?

Yes, Traffic Director provides load-balancing, routing and HTTP caching functionality out of the box: in 12c.  You can use Traffic Director as a reverse proxy to serve standard web server content: in 12c, we plan to add content serving functionality to provide a complete replacement for the traditional web server usage.

Is the PL-SQL Gateway available in 12c?

PLSQL Gateway is part of Oracle HTTP Server. Oracle HTTP SErver 11g is certified with WebLogic Server 12c and the PLSQL gateway will work via that route.

Since WebLogic won't support hypervisors other that Oracle VM, how can we leverage weblogic's cloud capabilities on our picked cloud providers which provide us some red hat, ubuntu or other operating system based VM's?

Please see the Support note on My Oracle Support for information on WebLogic support on virtualized OS: <a href='' target='_blank'></a>

Will Data Guard be required for data centre DR or can we still use file-based failover via SAN as with older versions?

Thanks for asking. You could use file-based failover.

Can WLS 12c, as middle tier, work with back-end, RAC systems?

Thanks for your question. Yes, you could use WebLogic Active GridLink to connect to Oracle RAC.

Oracle Traffic Director and Virtual Assembly Builder are available only for Exalogic?

Yes, for Oracle Traffic Director. Oracle Virtual Assembly Builder is available both off and on Exalogic.

Java SE/EE/JVM/JRockit

Can earlier versions of Java EE be deployed on WebLogic 12?

WebLogic Server 12c will not support Java SE 5 or JDK 5. WLS 12c will support application built using Java EE 5 because of the built-in compatibility provide between Java EE 5 and Java EE 6

Does WLS 12C support other Faces/AJAX GUI then ADF, like PrimeFaces, RichFaces, etc.?

Generally third party Java libraries and frameworks are expected to work on WebLogic Server as they would on any standards based Java EE Server. Oracle will ensure that if there are any issues with documented WebLogic Server APIs or if other documented features are not working with the third party usage that Oracle will fix those problems. Direct support or fixes for third party software and libraries, as expected is not provided by Oracle but would be provided through the providers of that software.

Is the Flight Recorder functionality in OEPE intended to replace JRockit Mission Control?

Mission Control/Flight recorder has a plug-in that can be used to enable viewing Mission Control in the OEPE/Eclipse framework. The stand-alone viewer is still available.

How well JRockit VM utilizes GC for huge heap sizes as 4Gb-8Gb

In 64-bit environments large heaps can increase GC times. JRockit RT and deterministic GC can help smooth this out and minimize pause times

Will the JCA Adapters plans (plan.xml) deployed over the cluster automatically?

Thanks for asking. No, it's planned.

Is JAX-RPC web services supported? If not what should be used instead fr reliable async WS?

Yes, it's supported.

Definitions of named queries?

The PersistenceContext is not recreated so that won't work.

are .ear files dead now? any reason why still to use them when EJBs can be deployed in .war files?

.ear file is still supported. It gives the option for dealing with complex Java EE applications, such as adapter, etc involved.

Does 12c use JDK 1.6 or 1.7?

WebLogic Server 12c can be run on either Java SE 6 or Java SE 7. From an EE perspective, it is fully Java EE 6 compatible. Java EE 7 is still being specified at this time so no product is compatible with it as it does not exist as a completed specification.

What is bundled jdk version? What is supported?

WebLogic 12c supports

JRockit and Hotspot JDK 6 and JDK 7. We bundle jdk 1.6, but also support JDK 1.7.

Has the WLS 8.x web service container (deprecated for some time) been removed in WLS 12c?


Will there be any modification for the JMX model that WebLogic used to support till 11g?

no fundamental changes here

It means J2EE6 will use common DD without any Vendor specific or what?

the deployment descriptor (web.xml) can be bypassed in favor of using specific annotations, but weblogic.xml can still be used

I missed the beginning of the presentation what are the plans around SCA support?

There is no plan to support SCA Java...what's there (SCA Spring C&I) is what it is.. Thanks for asking.

Is WebLogic 12c certified for both the full jee6 profile and the web profile?

The first release 12c will be EE6 full profile compatible. Since the web profile is a subset, you can run web profile apps on 12c.

Will there be an easier way to view JMS queue data in tables with LONG RAW than current version of WLS?

WebLogic 12c includes support for use of BLOBs in tables, as well as long raw, and WebLogic continues to support message management APIs to browse and view message contents. We are also looking at improvements in Fusion Middleware Control and Enterprise Manager for JMS management.

Is the converged JVM available standalone or only as part of Weblogic 12c?

JRockit and Hotspot are being converged to a single Java VM based on Hotspot. This was announced during the acquisition of Sun. This is expected to be completed over the next 12-24 months. Java Se 7 represents the converged JVM - you will gradually see Jrockit functionality like JR Mission Control and flight recorder appearing in it

What is "elastic message overflow" shown on the "200 improvements" slide?

Elastic message overflow is the ability for WebLogic JMS to take advantage of solid state disks, especially on Exalogic, for paging of JMS messages. This is especially important in spikes of traffic. Access to SSD is much faster than disks or the database, which are used for true persistent storage. This speed of writing and reading enables the system to absorb the spikes in traffic.

Any new JMS features in WLS12c?

12c inherits features that are rolled into WLS 10.3.6, especially performance improvements for the database store and some minor tweaks. We have additional new features planned for the next minor release of 12, but those plans are not public yet.

Do you support other languages such as Grails, Ruby, Scala and so on out of the box

Not with WLS, those are only supported on the JVM.

WebLogic 12c still run EJB 2 with Entity beans?

Yes, i think so, but to be honest i can't remember how far back the required compatibility is. if the Java EE spec madates compat as far back as EJB 2.0 it will be supported

I know WebLogic Server 10.3.6 is also going to be GA sometime next week. Does WebLogic Server 10.3.6 support Java 7 at GA?

 Plan of record is to make WebLogic 10.3.6 on JDK 7 in CY2011.

In 11g, we got some WebLogic specific monitoring in JRockit. Is there additional capability there in 12c, or will it be pretty much the same as in 11g?

In WebLogic Server 12c, the JRockit capabilities are effectively the same as in 11g. What is new in WebLogic Server 12c is support for Java SE 7, WebLogic Server running on the latest Java SE 7 release of Hotspot.

Install/Packaging/System Requirements/Versioning

Will there be a VM with WLS12c pre-installed available on OTN?

yes, one will be available around January for development use only, see

Are there any limitations in the ZIP distribution?

The ZIP distribution includes all WebLogic functionality and apps developed with the ZIP distro are supported on the full distro. It does not include Coherence, OEPE, Config Wizard, Upgrade tools, etc.

Which is the recommended amount of RAM for developer machines? For 11g it was 4GB afaik. Is that also streamlined with 12c?

Generally it can go quite small however the general recommendation is to start with 2G for best results for custom Java applications. For larger layered products in Fusion Middleware 4G may be necessary.

Note that WebLogic is meant to be a server, so often the default memory setting should be adjusted for local development.

11g to 12c, where come all these release versioning from?

Moving to 12c (12.1.1) is a major new release. When there is dramatic new functionality like Java EE 6 support and major new cloud support (thus the c in 12c), most vendors generally make version changes of this nature.

the WebLogic server 12c installer will include OVAB and OTD?

No: OVAB and OTD are both installed separately

Will Grid Control 12c WLS Management Pack be functional with WLS 12c servers as of next week's release?

EM 12c is integrated to support WebLogic Server 12c. The EM team is currently working on completing the final certification.

Do I need to install jrockit for weblogic 12c?

WebLogic windows and linux installers bundle JRockit. Some WLS installers do not include JVMs in which case you can install JRockit

Can weblogic12c be installed without coherence?

yes it can

Is the Coherence product (caching) bundled in this new 12c version or still a separate production?

Coherence is licensable as a separate product - Coherence SE, EE and Coherence Grid Edition- but it is also available included in the WebLogic Suite license.

If I download NB7.1 today do I get weblogic12?

Not bundled that way. They will work together, we just aren't bundling them in a installer together

Is the OTD included in the weblogic 12c standard edition? like the webcache is included in the weblogic 11g standard edition

No: OTD is licensed separately for Exalogic: full details will be available when OTD is GA.

Is Traffic Director licensed separately from WebLogic Server?

Oracle Traffic Director will be licensed as aprt of Exalogic Elastic Cloud Software.

WLS 12c is the marketing name, what is the software version... 10.3.6, 11.0, etc?

We have aligned the version number. The version is

Is 12c same as WL 10.3.6?

No. 12c is 12.1.1.

Do we get 12C (like with 11G) Standard and Enterprise (e.g. with JMS Clustering)?

The 12c packaging is the same as 11g.

Which previous versions of WebLogic will be a direct upgrade to 12c rather than a newinstall?

A new install will be required to use WLS 12c, but the upgrade from prior versions will be very smooth.

I thought that there would be a PatchSet5 version, is this now replaced by FMW 12c?

12c does not replace 11g PS5. WebLogic Server 12c is the next major release of WebLogic Server 11g (where WebLogic Server 10.3.6 is available).

Maven, Misc WebLogic Server features, documentation

Has the CAT been improved or is it the same version shipped with WLS 11g?

Fundamentally the same.

Is FastSwap also support changing of JPA entities in runtime?

It depends on what you are changing in your entities. If you add new entities, then no. The limitation woulds be related to the processing of annotations on JPA entities. What do you want to change?

What is WebLogic Server?

WebLogic Server is an application server for hosting Java aps

What about the documentation library? Will it be available on the same day as the software is published?

Yes it will :-)

What about WebLogic integration with CI tools?

I'm currently working on a demo that will shod how to create a WL domain, start a server, deploy an app, run tests and then stop the server all using Hudson. 11gPS3 supports Maven and 12c has new Maven functionality. Also supports ANT...

Could you please talk if we made any enchancements to taking applications that are developed in OC4J and deploy to WLS 12c?

Yes. There are lots of enhancements in this new WebLogic Server version, including Active GridLink support for Oracle RAC.

What resources are currently available for WebLogic 12c to get up to speed with the platform?

The data sheet will be available shortly on The documentation will be available with the download on

Does WLS12g still use the traditional HTTP session clustering or is it replaced with Coherence?

WLS still uses internal HTTP session clustering, and it also support Coherence*Web as an option

Does use of the filtering classloader still require an EAR, or is it now available in a WAR as well?

We have not changed this support

Customers often prefer to skip the first version of a new release of a product. Any reason why this is not the case for WLS12c? Does it contain bugfixes compared to 11.3.5?

Thanks for the good question! :) Yes, we have includes lots of bug fix on top of 10.3.5.

WebLogic 12c extensions will support Spring Framework 3.0 or 2.5 like in 11g?

WebLogic Server 11g Supports Spring 3.0 and so does WebLogic Server 12c

Where can I find the source for the ConferencePlanner application in the demo?

Is thread model similar to 11g?


Will WebLogic 12C or future releases support any out-of-box support for Continuous Integration or Test-Driven-Development with Hundon or Cruise Control?

In the Developer Webcast series in January we will be demonstrating this with hands-on labs.

Maven support is cool. Does it need maven 3.x or will it work with maven 2.x?

Maven 2.2.X and 3.0.X.

Is it possible to use production redeployment with the Maven plugin? If yes, can we use the retireTimeout option?

I don't believe we have certified this. Do you put release into production directly from Maven? I f you want more on this send me a note will.lyons at

Will the Maven plugins integration be available for 11g?

Yes, it's available with WebLogic 11g (10.3.4)

can maven build scripts be exported out of the eclipse ide

Support comes from M2Eclipse Sonatype plugin in Eclipse; don't know what they are capable of regarding export. I know you can execute maven goals though.

Would WebLogic 12c be used by oracle applications like ebs/siebel/peoplesoft/fusion??

It will be used by Oracle apps in the future releases.

Does mvn deploy goal also support redeploy? Do you have to undeploy your application before running this goal?

Yes it supports redeploy and you do not need to undeploy.

Can I use the maven improvements also with WebLogic 10?

The new features are only for only 12c, but the original 11g / Maven features are still there, of course

What does it mean maven?

<a href='' target='_blank'></a>/

Are the WebLogic maven artifacts going to be in a public repository? Or will I still have to manually add them to my repo?

They will not be in a public repository at this time. There is a public maven repository for EclipseLink JPA, however.

The ability to delete an Active (running) application is now available in WLS 12c?

No. Thanks for asking.

Getting your domain to start up automatic on server boot via the Node Manager is currently a bit cumbersome. Has this by any change been easier?

Other than some minor tweaks, the Node Manager is unchanged in WLS 12c.

Which version of Jython WLST is using for 12c?


Are there any cluster unicast health monitoring utilities included in 12c. (similar to weblogic multicast monuitor used to come with earlier versions)

we don't have planned enhancements in this area

Java ee 6 apps written for Glassfish will be compatible to WLS12c?

WebLogic will support use of Glassfish deployment descriptors. Apps that use the standard features should be deployable to WebLogic.

Can you please comment on osgi (bundles) support for wls 12c?

WebLogic Server uses OSGi for internal modularization. OSGi has also been used to deliver products like Oracle Complex Event Processor (CEP) in Oracle SOA Suite from WebLogic Server.

Does WLS 12c require a database? Can it stand alone without a database?

WLS does not require a database per se. It never has. There are some features that work with a database, such as database leasing for HA and JMS message storage.

Is there any improvement to support hibernate?

Like it worked with WebLogic Server 11g, Hibernate continues to work with WebLogic Server 12c


With this multiple servers (WebLogic, GlassFish, and now Oracle 12c), how Oracle is envisioning its future support for application services from a customer point of view?

WebLogic Server 12c is the continuation of the WebLogic Server product family. For management of multiple versions and products, Oracle Enterprise Manager Cloud Control is the recommended solution.

Will Oracle 12C support OSGI model?

WebLogic Server uses OSGi for internal modularization. OSGi has also been used to deliver products like Oracle Complex Event Processor (CEP) in Oracle SOA Suite from WebLogic Server.

How quick will WebLogic adapt EE 7?

EE7 has not been released yet, it is still being defined. Once it is released, WLS as always will support it. A specific date is not available at this time

How does it compete with IBM websphere?

We beat IBM in market share by over 10 points, we beat them in performance as we shared in the previous webcast and we beat them in innovation as indicated by this release and our vision and roadmap for Cloud. And WebLogic is in the #1 position for the relevant Gartner magic quadrant

Do you offer an alternative to WebSphere Portal Server for portal based projects?

Yes, we offer Oracle WebCenter - <a href='' target='_blank'></a>

Will you provide Amazon AMIs with WLS12c? For all regions :)?

While you can deploy it as an AMI, we are not providing any from Oracle

Will WebLogic have support for some php libraries?

We do not formally certify any specific Java PHP libraries on WebLogic Server 12c however there are Java implementations available you can try. Most folks use PHP in the Web Server tier - e.g. Apache mods.

Will have support for mysql databases?


Do you have plans to replace *.py in wst with other (more java like) scripting languages like groovy?

Not at this time.

Is there a plan to support Hadoop/NoSQL from WebLogic application server series in future?

Oracle has specific solutions around Big Data working with NoSQL and Hadoop. Check out: <a href='' target='_blank'></a> - a number of the products in that space do indeed run on WebLogic Server.

What will be the support for HTML 5 Web Sockets?

Oracle has announced Project Avatar at JavaOne 2011 which discussed adding HTML 5 and Web Sockets to the Java Platform. WebLogic Server already supports Comet for a pub/sub architecture today and will support Web Sockets/HTML 5 aligned with Project Avatar as that project comes to fruition in 2012.

What is the future of the WebLogic Suite Virtualization Option together with the JRockit Virtual Edition?

WebLogic Suite Virtualization Option will not be offered with WebLogic Server 12c

Will WebLogic patchset #5 also available?

Our plans are to release patchset 5 shortly. Specific dates are not available.

when I access I can't register for an account? when will it be available?

When you go to you can click on the "Notify Me of Updates" orange button and you can register for updates.

what is the future for glassfish relative to weblogic?

Oracle GlassFish Server is a commercial offering of GlassFish Open Source Edition. GlassFish serves several purposes including being the reference implementation of Java EE as well as being a hugely popular developer centric Java server solution. Oracle has customers running GlassFish in many different configurations from very small deployments to very large deployments but in general they tend to be smaller deployments and more developer driven versus large scale enterprise deployments.

WebLogic Server, on the other hand, has a significant number of enterprise features as noted here in the WebLogic Server 12c release and of course is the based on the same hardened reliable, highly available, scalable and proven performance application server infrastructure customers have been running in large scale enterprises for years. Now in WebLogic Server 12c this has been further extended to include deep Oracle RAC integration, native Coherence integration, full Enterprise Manager 12c manageability, diagnostics, administration, and an optimized virtualization infrastructure with Oracle Virtual Assembly Builder, amongst other extensions and features. These are capabilities that are not available on Oracle GlassFish Server. Customers generally either adopt WebLogic Server first, or upsize from GlassFish Server to WebLogic Server as their requirements demand it.

What of course is new and interesting in WebLogic Server 12c, on the developer side of things, is the Java EE 6 Full Profile compliance and has numerous developer features included to make the developer experience extremely fast, lightweight and agile. These include beyond Java EE 6, capabilities like direct Maven integration for dependency management, a lightweight zip distribution - approximately 168M which is almost 6X smaller than the full deployment platform distribution and finally certification and integration with Java SE 7.

Finally, in addition to these characteristics, another key issue for customers adopting WebLogic Server is that is the platform that Fusion Middleware, Fusion Applications and all of Oracle's portfolio of horizontal and vertical applications depend on as their enterprise Java Server. It has further specific optimizations for Exalogic Elastic Cloud that dramatically increase performance and reliability within the engineered systems approach Oracle is unique in providing with Exalogic. As such, most frequently customers adopt WebLogic Server for their enterprise scale Java applications for the developer and enterprise deployment features. If and when their infrastructures require other components of Oracle Fusion Middleware or Fusion Applications, WebLogic is generally the default choice due to the out of the box integration.

When will Oracle 12c be available as Oracle Public Cloud service?

WebLogic Server 12c is planned to be in the Oracle Public Cloud during calendar year 2012.


Can an 11g domain be upgraded to 12c?

Yes. You can use the upgrade tool to implicitly or explicitly upgrade the domain.

Are there any important changes for WLS12c admins on traditional HW compared to 11g (availability concepts, domains, startscripts, JMS admin etc)?

The upgrade to 12c is very straightforward. There is standard upgrade process to 12c as there has been from 9.2/10.0/10.3/11g. There are definitely enhancements around high availability, DR which were covered in the previous presentation. Very exciting release from a large scale deployment infrastructure. Check out the previous presentation - this one is focused on development.

seamless upgrade of jboss apps starting with what version of jboss?

We have a service with Oracle Consulting Services that will provide estimates and use tooling to facilitate upgrade. There is no specific version limitations.

Is it possible to upgrade from weblogic server 9.3 directly to 12c?

I think you mean WLS 9.2 MP3. Yes, upgrade will be supported from 9.2 MP3 to 12c.

What are the application migration tools and how can we learn more about them to upgrade from OAS to 12c

Oracle SmartUpgrade is the Java EE migration tool that helps you to move your custom app from OC4J to WebLogic Server. It's not certified with 12c yet.

Would there be a direct path to upgrade from 10.3 to 12c? Or we have to first go to 11g?

You can upgrade directly from 10.x to 12c.

Does WebLogic console utilize some Oracle technologies for creation web applications like JSF itself?

The WebLogic Server Admin console uses a portal-lite framework for most pages, as well as some advanced technologies in the Dashboard. Fusion Middleware Control uses ADF as a framework.

Will this WLS 12C can be configured with clustered Admin server?

The Admin Server is not clustered, although this is a topic of discussion internally. We continue to support managed server independence mode so that the Admin Server is not a single point of failure.

Does WLS12c control still require the nodemanager?

Yes, it's still needed.

Is the WLS console designed using Oracle ADF?


Will 11g configurations automatically be converted to 12c or will they run as-is?

It’s backwards compatible. So 11g config will work on 12c as well.

Are there plans to merge EM console along with the WLS Admin Console

Glad you asked! In the WebLogic 12c and Fusion Middleware 12c families, we are adding capabilities to Fusion Middleware Control and Cloud Control that are currently only available in the WLS Admin console. We will eventually phase out the WLS Admin console, but not during the 12c release family.

Is the performance on SuperCluster comparable to the Exalogic metrics?

Exalogic Elastic Cloud Software optimizations for WebLogic Server 12c are available on both the X2-2 Exalogic and Superclusters. Similar performance optimizations are available on both and dramatically improve performance on both architectures.

The traditional admin console is no more?

The weblogic server web based console is very much part of this release. It loads on first boot of WebLogic.

Can the underlying 11g FMW weblogic which is 11g be upgrade to 12c under same 11g FMW?

WebLogic 11g can be upgraded to WebLogic Server 12c - standard tooling exists to automate and simplify this. This applies to custom Java applications that are deployed on WebLogic Server 11g and third party applications running on WebLogic Server 11g that have also been certified on WebLogic Server 12c.  Fusion Middleware 11g is currently only certified on WebLogic Server 11g. We expect during CY 2012/2013 there will be incremental releases of Fusion Middleware 12c certified with WebLogic Server 12c.

When is end of support for weblogic 10.3.5

There will be a MOS note update covering this topic, but WLS 10.3.X will be supported through June 2014 (standard) and Juine 2017 (extended). Error correction support on WLS 10.3.5 will be provided until at least August 2013.

Almost 2 millions JMS messagess persisten or not?

I believe those are non-persistent messages, but I need to verify that. There are performance benefits on Exalogic for both persistent and non-persistent. For persistent, we have a fast pipeline to shared storage. For non-persistent, we improved some low-level handling that keeps the pipe full.

Did you improve WLS startup and deployment times?

Yes, this has been a continuing focus for us. In the dev presentation you will see some startup options tha enable to you to startup subsets of the server, the FastSWAP option for avoiding deployment entirely, and we continue to analsya and improve application deployment performance.

Java performance numbers are nice but Is the WLS 12c performance of the WLS admin console improved as well? On the admin console performance question I think we should say that there have been significant ongoing improvements to WLS Admin console performance over the WLS 10.3.X release cycle and those are included in WLS 12c. There are no fundamental architectural changes or significant performance changes in the WLS 12c console however.

in our organization we have oracle portal and we want to migrate to WebLogic 12c, this will be easy to do?

Oracle Portal currently runs on Oracle WebLogic Server 11g and there is a standard upgrade path to take customers to WebLogic Server as part of the 11g infrastructure. We have not announced plans for Oracle Portal (that is the Oracle iAS Portal) for WebLogic Server 12c.


which version of coherence will be supported on WLS 12c ?

Coherence 3.7.1

What is Coherence?

Coherence provides replicated and distributed (partitioned) data management and caching services on top of a reliable, highly scalable peer-to-peer clustering protocol. Coherence has no single points of failure; it automatically and transparently fails over and redistributes its clustered data management services when a server becomes inoperative or is disconnected from the network. When a new server is added, or when a failed server is restarted, it automatically joins the cluster and Coherence fails back services to it, transparently redistributing the cluster load. Coherence includes network-level fault tolerance features and transparent soft re-start capability to enable servers to self-heal
