EAServer 4.2.1 adds a new property for connection caches, to be set if the cache is used by an EJB CMP entity beans and the cache has set-proxy support enabled. The com.sybase.jaguar.conncache.ssa.systemid property specifies an alternate user name to set proxy to.
In an EJB CMP entity bean, the client user name is not available to set proxy to since the persistence engine runs as the system user. In this case, if a user name is specified with this property, the cache manager sets proxy to the specified user. Otherwise, it sets proxy to the cache’s User Name.
