Oracle WebLogic Server Now Running on Docker Containers

We are very excited to announce that Oracle WebLogic Server is now certified to run on Docker containers. As part of the certification, we are releasing Dockerfiles and supporting scripts on GitHub to build images for Oracle WebLogic Server.  These images are built as an extension of existing Oracle Linux images Oracle Linux Images. You can use these Oracle WebLogic Server Docker images or create your own. To help you with this, we have posted Dockerfiles and scripts on GitHub as examples for you to get started.

Docker is a platform that enables users to build, package, ship and run distributed applications. Docker users package up their applications, and any dependent libraries or files, into a Docker image. Docker images are portable artifacts that can be distributed across Linux environments. Images that have been distributed can be used to instantiate containers where applications can run in isolation from other applications running in other containers on the same host operating system.

The table below describes the certification provided for various WebLogic Server versions. You can use these combinations of Oracle WebLogic Server, JDK, Linux and Docker versions when building your Docker images.

 Oracle WebLogic Server
JDK Version
Host OS
Kernel Docker Version
 12.1.3  7/8  Oracle Lunux 6 UL 5+
 Unbreakable Enterprise Kernel Release 3 (3.8.13)+
 1.3.3+
 12.1.3  7/8  Oracle Linux 7 UL 0+

 Unbreakable Enterprise Kernel Release 3 (3.8.13)+

or

Red Hat  Compatible Kernel (3.10)+

 1.3.3+
 12.1.3  7/8

 Red Hat Enterprise

Linux 7+

 Red Hat  Enterprise Linux Kernel (3.10)+  1.3.3+

For additional details on the most current Oracle WebLogic Server supported configurations please refer to Oracle Fusion Middleware Certification Pages.

These Dockerfiles and scripts we have provided enable users to create clustered and non-clustered Oracle WebLogic Server domain configurations, including both development and production running on a single host operating system or VMs. Each server running in the resulting domain configurations runs in its Docker container, and is capable of communicating as required with other servers. For documentation on how to use these Dockerfiles and scripts, see the whitepaper on OTN. Other configurations and approaches are possible, but we hope these help get you started. We look forward to your feedback.

Calling All WebLogic Users: Please Help Us Improve WebLogic Documentation!

Great documentation is key to the usability of any good product - WebLogic is most certainly not an exception. The WebLogic documentation team tries hard to do the best job they can. It's not a particularly easy job with a product as feature rich as WebLogic that has a continuous cadence of evolution.

The best way to make sure we have great documentation is getting feedback from you - the user. For this reason we are collecting feedback through an open survey on WebLogic documentation. The public survey is available here. The survey is just two pages, should take you a few minutes to fill out and will greatly help the WebLogic user community. Your opinion is worth it's weight in gold!

As a reminder, the latest WebLogic documentation is available here.

The survey is slated to close the end of February, but could be extended if there is a sustained stream of feedback.

Exciting New JTA 12.1.3 Feature “XA Transaction without Transaction Logs”

One of the most exciting new features in WebLogic Server 12.1.3 is a JTA new feature
“XA Transaction without Transaction Logs.” This feature does not only provide performance optimization when applications use XA transactions, but also has great advantages for Disaster Recovery scenarios.

XA transactions provide a standards-based mechanism to preserve data integrity for mission-critical applications. Traditionally XA transaction recovery requires the transaction manager to persist transaction records to stable storage (TLog) after all of the transactions resources have been prepared, and purging them after all of the transactions resources have been completed. However, recording pending transactions for recovery purposes requires additional I/O which affects performance. In cases of disaster recovery transaction logs need to be replicated to make sure that global transactions can be recovered.

XA Transaction without Transaction Logs,” uses a determiner resource which can be either a DataSource or a WebLogic JMS resource to determine the recover outcome of pending transactions. When using a determiner resource, WebLogic Server will no longer write and purge transaction checkpoints to TLogs. XA Transaction without Transaction Logs,” takes advantage of the two-phase-commit protocol, as well as prepare and commit ordering of resources participating in the global transaction to determine if pending transactions need to be recovered with a commit or a rollback.

The advantages of this feature are:

· Up to three times performance throughput improvement

· Prepare and Commit ordering

· I/O latency removed by not writing to TLOG (default file store)

· Resource and/or batch blocking removed (JDBC Tlog)

· Memory consumption reduced

· Capacity requirements reduced

· TLOG replication made easy

In WebLogic Server 12.1.3 “XA Transaction without Transaction Logs,” is restricted to transactions that involve a single Transaction Manager (WebLogic Server). The mixture of transactions that enlist determiner resources and span single Transaction Managers, with those who do not enlist a determiner resource and/or span multiple Transaction Managers is supported. In the future, WebLogic will support not logging transactions that involve multiple Transaction Managers.

Check out the YouTube recordings that go into detail how this feature works "JTA 12.1.3 New Feature and Optimization". There is even a demo that shows you how it is configured, how it works, and how you can debug your transactions to verify if the determiner is working "XA Transaction without Transaction Logs" and Demo.

Refer to the WebLogic Server 12.1.3 documentation JTA documentation "XA Transaction without Transaction Logs" for further details on how to configure and use the feature.

WLS 12.1.2 and MultiTenant Databases

Oracle WebLogic Server release 12.1.2 has integrated support for the Oracle Database 12c features, particularly Application Continuity, Transaction Guard, Database Resident Connection Pool, Multi Tenant Databases, and Global Data Services. WLS integration to these new 12c database features is described in this white paper WebLogic 12c integration to Oracle Database 12c features.

The integration to Multi Tenant Database or Pluggable Database increases elasticity, scalability, and enables multitenancy. Pluggable Database implementations allow multiple distinct databases in a single, larger database installation. The Container Database (CDB) feature in Oracle Database 12c minimizes the overhead of these multi-database configurations by consolidating them into a single database with multiple Pluggable Databases (PDB) in a single Container Database. For more information about using this feature in WLS, see https://blogs.oracle.com/WebLogicServer/entry/part_3_12c_database_and

In Oracle WebLogic Server, you can use a single data source to pool connections to multiple pluggable databases. The application at run time can switch between PDB's by calling ALTER SESSION SET CONTAINER. This model provides the benefits of the Multi Tenancy option at the mid tier in addition to the data tier, including scalability and elasticity.

You should be aware of some limitations of PDB switching with Oracle Database 12.1. The following WebLogic Server limitations exist when using tenant switching.

  • Oracle RAC Fast Application Notification (FAN) is not supported. Even though FAN is not supported, Active GridLink still provides the benefit of a single data source view of multiple RAC instances and the ability to reserve connections on new instances as they are available without reconfiguration using connection load balancing. If you want to use tenant switching with an Active GridLink data source, “FAN enabled” must be set to false see http://docs.oracle.com/middleware/1212/wls/JDBCA/gridlink_datasources.htm#CHDIAGEF . Generic data sources don’t use FAN so this restriction doesn’t apply.

  • Database Resident Connection Pool (DRCP) is not supported

  • Application Continuity is not supported.

  • Proxy authentication is not supported.

  • Recovery of XA transactions in single data source that is used for switching between multiple PDB's is not supported.

For more details about these limitations read the documentation http://docs.oracle.com.middleware/1212/wls/JDBCA/ds_oracledriver.htm#CCHBDGHC.

New WebLogic Server 12.1.2 Installation and Patching Technology


WebLogic Server 12.1.2 has many new features, but the first new feature you are likely to notice is the change in installer technology. WebLogic Server and Coherence 12.1.2 are installed using Oracle Universal Installer (OUI) installer technology. We have also changed WebLogic Server patching technology from SmartUpdate to OPatch, the patching tool used to patch OUI installations. Note that installation and patching technology used for prior versions of WebLogic Server has not changed.

The primary motivation for this change is to provide consistency across the Oracle stack. Prior to WebLogic Server 12.1.2, Fusion Middleware customers were required to use different technologies to install and patch, for example, Oracle Application Development Framework (ADF) with WebLogic Server. Now users can perform installation and patching across products more efficiently by using the same technologies, and by using new installation packages that simplify installation of Fusion Middleware products with WebLogic Server. Check the YouTube video that describes how to install  WebLogic Server 12.1.2 using the  OUI installer http://www.youtube.com/watch?v=SDT3UMXSAFc.

The following WebLogic Server distributions are now available on the Oracle Technology Network (OTN) http://www.oracle.com/technetwork/middleware/weblogic/overview/index.html  under OTN license, and from Oracle Software Delivery Cloud (OSDC)  https://edelivery.oracle.com for licensed customers:

wls_121200.jar - This OUI installer package includes WebLogic Server and Coherence and is targeted at WebLogic Server users who do not require other Fusion Middleware components such as ADF. This generic installer can be used to install WebLogic Server and Coherence on any supported operating system, and is intended for development or production purposes. This is available on OTN and OSDC.

· wls1212_dev.zip – This zip package includes the same core WebLogic Server and Coherence technology provided in wls_121200.jar, but removes certain Oracle components that are only required for production use cases. It is intended as a lightweight download for development purposes – unzip and run the included script. It is available on OTN only, along with a supplemental examples package. Note that patching of the zip distribution is not supported.

August 21, 2013: an updated package of the WebLogic Server 12.1.2.0.0 zip distribution was released to OTN. This update resolves a minor problem in the original (GA) WebLogic Server 12.1.2.0.0 zip distribution when starting the Configuration Wizard GUI.

· OEPE  Installers – including WebLogic Server, Coherence, ADF, Fusion Middleware Control, and Oracle Enterprise Pack for Eclipse (OEPE). These OUI installers contain the latest updates to Oracle Enterprise Pack for Eclipse, Oracle’s Eclipse-based IDE, with distributions for Windows, Linux and Mac OS X. These installers are intended for development purposes and are available on OTN only.

· wls_jrf_121200.jar - This OUI installer package includes everything that is included wls_121200.jar, and adds software components required to run ADF and Fusion Middleware Control. This installer is intended for development or production purposes and is available on OTN and OSDC.

· JDeveloper Installers – including WebLogic Server, Coherence, Oracle JDeveloper, ADF and Fusion Middleware Control. These OUI installers contain the latest updates to Oracle JDeveloper 12.1.2, Oracle’s strategic IDE for developing Fusion Middleware applications, with distributions for Windows, Linux and generic operating systems. These installers are intended for development purposes and are available on OTN and OSDC.

For more information on the above, refer to the appropriate product documentation, for example, for documentation on installation of wls_121200.jar, see http://docs.oracle.com/middleware/1212/core/WLSIG/planning.htm#WLSIG237.
