When you use IBM Web Content Manager with WebSphere Portal Version 220.127.116.11 and apply APAR PM63259, you can cache fully rendered pages in WebSphere eXtreme Scale V7.1.1 and WebSphere DataPower XC10 Version 18.104.22.168 by way of the standard WebSphere dynamic cache APIs.
You can now store the dynamic cache content in a remote grid that is hosted by WebSphere eXtreme Scale Version 7.1.1 or WebSphere DataPower XC10 Version 22.214.171.124 for IBM Web Content Manager with WebSphere Portal Version 126.96.36.199. Therefore, data that is inserted into the dynamic cache does not consume application server heap space for IBM Web Content Manager with WebSphere Portal Version 188.8.131.52.
This support provides an IBM Web Content Manager with WebSphere Portal Version 184.108.40.206 environment with the following benefits:
- Elimination of disk storage as a performance bottleneck. One of the potential performance constraints in a dynamic cache environment results from processing overhead incurred during the swapping of cache objects that are paged to disk.
- Reduction of processing overhead and latency that is associated with exchanging invalidation information between physically separate cache instances. An eXtreme Scale instance is managed as a single, addressable memory space without physical partitions between instances that need to check and invalidate cache objects within each instance. Instances are managed in this way to maintain consistency and to avoid network bandwidth penalties that are typically associated with performing such operations. Therefore, invalidation processing is entirely eliminated or reduced, depending on the server configuration.
- Significant reduction in the time to reach or to return to a steady state of a website after performing one or more of the following operations: full website restart, partial website restart, and complete or partial cache invalidation.
- Larger total cache size than the local application server heap can originally support. The cache now scales elastically, reducing long garbage collection pauses, while improving application response time.
