Oracle WebLogic Server 12.2.1.1 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 12.2.1.1, which is the first patch set release for WebLogic Server and Fusion Middleware 12.2.1.   New WebLogic Server 12.2.1.1 installers are now posted on the Oracle Technology Network and Oracle Software Delivery Cloud, and new documentation has been made available.  WebLogic Server 12.2.1.1 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 12.2.1.1 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 12.2.1.1 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 12.2.1.1 today.   Try it out and give us your feedback!

So what is Active GridLink for RAC?

I had referred to Active GridLink for RAC in my blog yesterday and since then got several questions on this topic. So I decided to re-visit Active GridLink. With the release of version 11g, Oracle WebLogic Server started to provide strong support for the Real Application Clusters (RAC) features in Oracle Database 11g, minimizing database access time while allowing transparent access to rich pooling management functions that maximizes both connection performance and availability. WebLogic is the only application server in the marketplace which has been fully integrated and certified with Oracle Database RAC 11g without losing any rich functionality. Active GridLink provides Fast Connection Failover (FCF), Runtime Connection Load-Balancing (RCLB), and RAC instance graceful shutdown. With the key foundation for providing deeper integration with Oracle RAC, this single data source implementation in Oracle WebLogic Server supports the full and unrestricted use of database services as the connection target for a data source.


For more details and to understand how our customer NEC leverages this capability, read the whitepapers on this topic.

Get in depth ‘how-to’ details from this youtube video from our resident expert, Frances Zhao.
