Error description
Websphere Dynamic Cache instances cannot be mapped to different dynamic map instances in WebSphere Extreme Scale
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All WebSphere eXtreme Scale dynamic cache * * users who want to have multiple cache * * instances with the same name correspond to * * different maps within the same data grid. * **************************************************************** * PROBLEM DESCRIPTION: Dynamic cache instances with the same * * name but different application server * * JVMs cannot use the same data grid * * instance. * **************************************************************** * RECOMMENDATION: * **************************************************************** With WebSphere eXtreme Scale, multiple WebSphere Application Server application server JVMs might need to use the same data grid instance. Using the same data grid instance can be problematic if the different application server JVMs do not want to share the same data. With the default dynamic cache instance (baseCache), this limitation is a problem because you cannt change the name of this cache instance within the application server.
Problem conclusion
The com.ibm.websphere.xs.dynacache.cache_name cache custom property was introduced. The value of this property is used as the name of the cache within the data grid. For example, if you have two application servers, you can use this custom property to configure the baseCache instances to correspond to separate maps within the data grid. For example, you might use the names baseCache1, baseCache2, and so on.
