Garbage collection

WebSphere eXtreme Scale creates temporary objects that are associated with each transaction, such as request and response, and log sequence. Because these objects affect garbage collection efficiency, tuning garbage collection is critical. For the IBM virtual machine for Java, use the optavgpause collector for high update rate scenarios (100% of transactions modify entries). The gencon collector works much better than the optavgpause collector for scenarios where data is updated relatively infrequently (10% of the time or less). You will need to experiment with both collectors to see what works best for the application.

WebSphere eXtreme Scale can run on various versions of Java 2 Platform, Standard Edition (J2SE). WebSphere eXtreme Scale v6.1 supports J2SE v1.4.2 and later. For improved developer productivity and performance, use J2SE 5 or later to take advantage of annotations and improved garbage collection. WebSphere eXtreme Scale works on 32-bit or 64-bit JVMs.
