WebLogic Server Continuous Availability in

We have made enhancements to the Continuous Availability Offering in WebLogic in the areas of Zero Downtime Patching, Cross Site Transaction Recovery, Coherence Federated Caching and Coherence Persistence. We have also enhanced the documentation to provide design considerations for the multi-data center Maximum Availability Architectures (MAA) that are supported for WebLogic Server Continuous Availability.

Zero Downtime Patching Enhancements

Enhancements in Zero Downtime Patching support updating applications running in a multitenant partition without affecting other partitions that run in the same cluster. Coherence applications can now be updated while maintaining high availability of the Coherence data during the rollout process. We have also removed the dependency on NodeManager to upgrade the WebLogic Administration Server.

  • Multitenancy support
  • Application updates can use partition shutdown instead of server shutdowns.
  • Can update an application in a partition on a server without affecting other partitions.
  • Can update an application referenced by a ResourceGroupTemplate.
  • Coherence support - User can supply minimum safety mode for rollout to Coherence cluster.
  • Removed Administration Server dependency on NodeManager – The Administration Server no longer needs to be started by NodeManager.

Cross-Site Transaction Recovery

We introduced a “Site Leasing” mechanism to do auto recovery when there is a site failure or mid-tier failure. With site leasing we provide a more robust mechanism to failover and failback transaction recovery without imposing dependencies on the TLog which affect the health of the Servers hosting the Transaction Manager.

Every server in a site will update their lease. When the lease expires for all servers running in a cluster in Site 1, servers running in a cluster in a remote site assume ownership of the TLogs, and recover the transactions while still continuing their transaction work. To learn more, please read Active-Active XA Transaction Recovery.

Coherence Federated Caching and Coherence Persistence Administration Enhancements

We have enhanced the WebLogic Server Administration Console to make it easier to configure Coherence Federated Caching and Coherence Persistence.

  • Coherence Federated Caching - Added the ability to setup Federation with basic active/active and active/passive configurations using the Administration Console and eliminated the need to use configuration files.
  • Coherence Persistence - Added a persistence tab in the Administration Console that provides the ability to configure Persistence related settings that apply to all services.


In WebLogic Server we have enhanced the document Continuous Availability for Oracle WebLogic Server to include a new chapter “Design Considerations for Continuous Availability” See http://docs.oracle.com/middleware/12211/wls/WLCAG/weblogic_ca_best.htm#WLCAG145.

This new chapter provides design considerations and best practices for the components of your multi-data center environments. In addition to the general best practices recommended for all continuous availability MAA architectures, we provide specific advice for each of the Continuous Availability supported topologies, and describe how the features can be used in these topologies to provide maximum high availability and disaster recovery.

Oracle WebLogic Server is Now Available

Last October, we delivered Oracle WebLogic Server 12.2.1 as part of the overall Oracle Fusion Middleware 12.2.1 Release.   As noted previously on this blog, WebLogic Server 12.2.1 delivers compelling new feature capabilities in the areas of Multitenancy, Continuous Availability, and Developer Productivity and Portability to Cloud.  

Today, we are releasing WebLogic Server, which is the first patch set release for WebLogic Server and Fusion Middleware 12.2.1.   New WebLogic Server installers are now posted on the Oracle Technology Network and Oracle Software Delivery Cloud, and new documentation has been made available.  WebLogic Server contains all the new features in WebLogic Server 12.2.1, and also includes an integrated, cumulative set of fixes and a small number of targeted, non-disruptive enhancements.   

For customers who have just begun evaluating WebLogic Server 12cR2, or are planning evaluation and adoption, we recommend that you adopt WebLogic Server so that you can benefit from the maintenance and enhancements that have been included.   For customers who are already running in production on WebLogic Server 12.2.1, you can continue to do so, though we will encourage adoption of WebLogic Server 12.2.1 patch sets.

The enhancements are primarily in the following areas:

  • Multitenancy - Improvements to Resource Consumption Management, partition security management, REST management, and Fusion Middleware Control, all targeted at multitenancy manageability and usability.
  • Continuous Availability - New documented best practices for multi data center deployments, and product improvements to Zero Downtime Patching capabilities.
  • Developer Productivity and Portability to the Cloud - The Domain to Partition Conversion Tool (D-PCT), which enables you to convert an existing domain to a WebLogic Server 12.2.1 partition, has been integrated into with improved functionality.   So it's now easier to migrate domains and applications to WebLogic Server partitions, including partitions running in the Oracle Java Cloud Service. 
We will provide additional updates on the capabilities described above, but everything is ready for you to get started using WebLogic Server today.   Try it out and give us your feedback!

New Partner Solutions on WebLogic and the Oracle Database Appliance

With the latest release of WebLogic on ODA, which now supports the X5-2 hardware, we have come to a new chapter. Oracle partners around the world have been developing customized solutions using WebLogic on ODA for years now. Many of them started with the wizard-driven templates produced by the Oracle WebLogic engineering team, and then went on to design their own customized solutions by expanding on and embellishing these templates for their customers' unique needs.

It became obvious that, to best support our existing users, and to give new customers more immediate access to the tools and resources they need for success, we would formalize this direction by shifting resources to enable Oracle WebLogic 12c specialized partners to rapidly gain expertise and traction in this arena.

To this end, we are publishing a new whitepaper how-to guide, Running Middleware Applications on ODA Machines, that can be used by partners or end users to speedily deploy a highly available platform on which to run Java applications. We are also announcing that this latest release of the WebLogic templates is also our final release. However, we will continue to encourage and support customer and partner led development efforts.

Attend a webinar on September 4th at 10am PT, to better understand what is in the latest release of WebLogic on ODA, and to hear directly from one of our expert partners on some of the solutions currently offered on ODA. http://ouweb.webex.com, Session Number: 599 716 170. Dial in: 877-814-3159 or 706-634-9616; Passcode: 210550.

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:
