WebLogic Server and the Oracle Maven Repository

http://maven.oracle.com

The Oracle Maven Repository has just gone live and is now available for public access. 

This really is excellent news and provides developers with free and easy access (registration required) to APIs, libraries and utilities they regularly use to build applications with WebLogic Server. 

From a WebLogic Server perspective, the Oracle Maven Repository provides publicly accessible, online, on-demand access to the full set of Maven product artifacts that have been provided in the 12c (12.1.2, 12.1.3) releases. This includes the WebLogic Server APIs, the client libraries and the WebLogic Server Maven Plugin.  It also includes the similar set of Coherence artifacts that ship within the WebLogic Server product distributions as well as other artifacts from the Oracle Fusion Middleware stack. 

To access the Oracle Maven Repository, there are two fundamental requirements to be aware of:

1. You must be using Maven 3.2.5 or later.  This contains the version of the component (Wagon 2.8) that has been enhanced to support access to artifacts that are protected by HTTP authentication schemes.

2. You must be registered with OTN and have accepted the agreement to access and use the Oracle Maven Repository.  This can be done with either a new or an existing OTN user account by accessing the http://maven.oracle.com site and clicking the registration link.  

Once registered, you then just need to configure your local Maven environment with the details of the Oracle Maven Repository, including information that relates to the authentication model specifying your OTN username and password.  Thorough documentation is provided and linked to from the main Oracle Maven Repository page.

The Maven provided password-encryption feature can be used to securely encrypt the password for convenient storage in a configuration file so that is not stored in human readable form and can be presented automatically when requested as part of accessing the Oracle Maven Repository. 

Once the repository is configured, developers can include dependencies on WebLogic Server artifacts in their projects and have them automatically retrieved from the Oracle Maven Repository as needed when the projects are being built or tests are being run from a Continuous Integration environment. 

The Oracle Maven Repository provides a significant step up for developer ease-of-use and productivity when working with WebLogic Server.

Can you put a dollar value on saving lives?

Did you know that dirty water kills about 5000 children per day? This according to The Guardian, a Pulitzer prize winning British newspaper. That's almost 2 million children per year! And this is not counting people who fall sick from ingesting dirty water and the lack of productivity for parents and children who invest [waste?] a fair part of their day in search of clean water. Heartbreaking! This is why Safe Water Kenya was born and Don Arnold, a veteran of the plumbing industry, took it upon himself to leverage his expertize and correct this situation.


Although Don started with Kenya, Safe Water has plans to expand to Ghana, Uganda and greater part of Africa. Once Oracle and mFrontiers joined hands with Don, we encouraged him to expand to Asia, where, inspite of all the progress and countries being super powers and what not, a vast majority of the people still dont have access to clean water.

Come and listen to this heart warming story of how Safe Water leveraged a Mobile app built on enterprise software technology, like WebLogic and the Oracle Database, to provide clean water to Kenyans and to provide accountability to its donors with complete and immediate transparency.

What does a Telecom Services Provider have in common with a Travel Group?

Verizon Communications and TUI Travel are winners of the Oracle Excellence Awards for Fusion Middleware Innovation for the Cloud Application Foundation category at this year's OpenWorld. They were honored at the Oscar-like ceremony held on Tuesday, Sept 30th. [You can find an overview of the Fusion Middleware Innovation Awards Ceremony and the full list of winners across all 12 categories in the following blog post: And The Winners Are.... ].

Verizon's goal was to build a robust, high-availability solution that provides responses in less than 500 milliseconds while ensuring data integrity across multiple data centers. They wanted to create a common service layer and expose the in-memory grid as a service, which will allow other systems to leverage this platform and provide a better customer experience. The Verizon system now caches the entire customer base on Oracle Coherence grid (5 TB across multiple data centers) which reduces the load on the back-end Oracle Database by about 60 percent and improves the response time from 2.8 second to approx. 0.3 seconds. The Coherence grid-as-a-service enables customer information to be stored in one place and provides a 360-degree view of the customer from ordering to billing. 


The use case for TUI Travel, as expected, is very different. TUI's new transfer redesign project included a complete new set of functionalities to ensure that transfers during travel could be sold door to door or from any place to any place. In order to achieve this, a point in polygon algorithm is loaded in the Coherence Grid. This can detect if a given GPS point is inside the subset of polygons loaded into each Coherence grid node. Instead of refreshing (polling) the data from the database to Coherence, TUI Travel uses Golden Gate HotCache to push the changes to Coherence as soon as they happen. WebLogic 12c helps TUI to do side by side deployments and enables horizontal scaling. WebLogic also enabled TUI to reduce risks in the deployment and minimize total time for deployment.

Congratulations to Verizon and TUI Travel for winning this year's Oracle Excellence Awards for Fusion Middleware Innovation in the Cloud Application Foundation category! 

Oracle Uses WebLogic, Database, Enterprise Manager to Strengthen Cloud Security and Optimize Performance

Oracle overall develops database and middleware software, application software, and hardware systems for their customers. But, we also eat our own "dog food" when it comes to the cloud, security and Big Data principles. As you learned at Open World 2014, we're focused on driving transformation in the cloud and bringing a unified platform to the market that will allow maximum flexibility, availability and choice. We can do that by leveraging the same products we sell (like WebLogic) but leveraging their strength in our own internal services.

For example, Oracle is enabling near-real-time analysis of its cloud systems’ behavior by various means, including Oracle WebLogic Server Diagnostic Framework, Oracle Enterprise Manager Monitoring Templates and corrective actions, and by collecting and analyzing hundreds of metrics and log files on a near-real-time basis.

Further, Oracle is using big data to improve cloud environment performance and ensure service-level-agreement compliance, which includes latency of less than one second. For example, it can now rapidly and effectively track and analyze how Java Virtual Machines in Oracle Public Cloud are using heap memory.

In these types of ways, by utilizing the products we already have, we're demonstrating a commitment to stability, ease of use, security and usefulness of the Oracle Cloud.

Maybe start out with a free trial of our WebLogic-in-the-cloud solution, Java Cloud Service. It's easy to try - Larry even gave a demo of it during one of his keynotes and noted how he was confident it would work in a live situation. And of course, it went off without a hitch.

More details on this topic can be found in a broader Oracle case study - on ourselves.

Improved High Availability with Whole Server Migration on Dynamic Clusters

If you remember, we added Dynamic Clusters in WebLogic Server 12.1.2. Dynamic Clusters make it really easy to configure a cluster and to scale up that cluster. They are a cloud-enabling technology that provides elasticity for your applications. We’re always looking to improve on a good thing, so in WebLogic Server 12.1.3, we enabled Whole Server Migration with Dynamic Clusters. Whole Server Migration enhances the availability of clusters by enabling a failing/failed managed server to be restarted automatically on a different machine. This is especially important for recovery of persistent JMS messages and distributed transactions.

I just posted a video on YouTube with more details and a short demo. Take a look:

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.

Oracle WebLogic Server 12.1.3 Whitepaper - Developing with WebLogic Server

One of the most significant areas of investment in WebLogic Server 12.1.3 has been in developer productivity and API updates, as I summarized in my blog from last week.   However, a brief summary is typically not enough for developers who want a more detailed description of the improvements we have delivered.   And although product documentation contains all of the relevant updates, sometime it does not capture the overall background on the topic that puts the improvements into context.  

Steve Button from the WebLogic Server product management team has published an excellent whitepaper on OTN - Oracle WebLogic Server 12.1.3 Whitepaper - Developing with WebLogic Server - which provides a detailed description of the new features, along with the background which explains why we delivered the improvements, and the benefits they offer.   The whitepaper covers new WebLogic Server 12.1.3 features in the areas of WebSocket, JSON, JAX-RS, JPA, Server-Sent Events, Maven and more.

If you are a WebLogic Server user looking for a detailed description of the latest development features in WebLogic Server 12.1.3, and how you can leverage them in your applications, this is an excellent resource.   Please take a look!

Oracle WebLogic Server 12.1.3 is Released

We're proud to announce that Oracle WebLogic Server 12.1.3 has been released as part of the Cloud Application Foundation and Oracle Fusion Middleware 12.1.3 release as described at the Cloud Application Foundation Blog. Oracle WebLogic Server is the industry's leading application server, providing unparalleled choice for deploying applications in public clouds, on-premise private clouds, engineered systems such as Oracle Exalogic Elastic Cloud, Oracle SPARC SuperClusters, and Oracle Database Appliance systems, and conventional systems.

Oracle WebLogic Server 12.1.3 is a new version release of Oracle WebLogic Server 12c.   It builds on the features provided in WebLogic Server 12.1.2 to improve developer productivity, performance and high availability, and manageability.   It enables you to develop and deliver innovative applications, to meet the application service level requirements for your business, and to manage your application infrastructure efficiently to achieve low total cost of ownership.

For developers we have placed specific focus on enabling development of server applications that support rich client applications running in HTML5 browsers or mobile devices. Such applications typically rely on REST based Web Services, use JSON as the data format for message payloads, and often require dynamic updates between clients and servers. In Oracle WebLogic Server 12.1.3, we have implemented support for selected Java EE 7 APIs including JAX-RS 2.0, Java API for JSON Processing, Java API for WebSocket, and JPA 2.1, to enable and support development of such applications.  We have also delivered related value-added capabilities like support for Server-Sent Events and unique WebSocket emulation capability.

High availability and performance improvements include improvements to Oracle Database 12c integration support - we have bundled the latest version of the Oracle Database 12c driver for ready access to database integration features, and have certified Oracle Database 12c AQ JMS as a Foreign JMS Server within Oracle WebLogic Server.    Innovations to the Oracle WebLogic Server transaction processing subsystem enable elimination of transaction logs in many cases, increasing performance and simplifying distaster recover configuration.   Optimizations for Oracle Exalogic systems include JMS performance improvements, and Cooperative Memory Management to adapt server memory usage based on memory consumption on Oracle Exalogic systems.

Manageability enhancements include improvements to dynamic clusters introduced in Oracle WebLogic Server 12.1.2.   In Oracle WebLogic Server 12.1.3 we support use of whole server migration to provide improved availability for dynamic clusters environments using JMS.    We have expanded our support for REST-based management, adding lifecycle management, application deployment, and datasource configuration support via REST.   We have also made similar improvements to support for Oracle WebLogic Server management in Oracle Fusion Middleware Control.

Finally, Oracle WebLogic Server 12.1.3 is the foundation of the Oracle Fusion Middleware 12.1.3 release, which adds Oracle SOA Suite 12c and other Oracle Fusion Middleware products to the family of products that is supported with Oracle WebLogic Server 12c.  This will make it easy for Oracle WebLogic Server 12.1.3 customers to adopt the latest releases of these products, and will also enable Oracle Fusion Middleware users to take advantage of the latest features in WebLogic Server 12.1.3.  To learn more:

...and look for more information from us in the coming days and weeks.  Thanks!
