This APAR is a cumulative fix of several problems. The Problem Summary section lists all of the included fixes.


The following items are the field APARs addressed in this
cumulative fix.


The following items are the additional fixes included in this cumulative fix:

1. Fixed the MapRangeIndex interface to correctly process attributes on composite keys for non-entity Maps.
2. Enabled ObjectQuery support of super-class field and property discovery for composite keys and embedded types.
3. Provided configuration options for setting the listener host and port for eXtreme Scale clients. This configuration option allows the AgentManager and ObjectMap.clear APIs to work properly in virtualized or multi-homed networks.
4. Fixed the AgentManager and ObjectMap.clear APIs to work correctly when SSL is enabled.
5. Fixed the MapIndexInfo.getTransactionChanges method to include invalidated entries.
6. Fixed the xsadmin sample to work when integrated with WebSphere Application Server on the Windows operating system.
7. Fixed MBean ObjectNames so that property values are set correctly.
8. Fixed the AgentManager API to correctly use the provided CredentialGenerator plug-in.
9. Improved server shutdown to avoid deadlocks and the System.exit() method from being called.
10. Fixed transaction timeout issues on replica shards.
11. Fixed deadlock that might occur when using the ObjectMap.clear method.
12. Fixed core group membership to be domain qualified.
13. Provided means to swap the role of a replica shard with that of a primary.
14. Fixed the IllegalStateException exception that can occur during failover with the message: "The mapSetName argument must not be null."
15. Updated to allow the JMX port to be set using the system property.
16. Fixed parallel container startup core group membership that might transiently display two groups instead of one.
17. Improved TTL eviction algorithm for memory based eviction.
18. Corrected exception chaining on the client to include the application exception from the server.
19. Provided default transaction time out value of 600 seconds. All transactions types time out after the transaction time out value is reached.
