This APAR is a cumulative fix for ObjectGrid. The resulting Interim Fix for this APAR can be applied to either WebSphere Extended Deployment Version 6.1.0.3 or Version 6.1.0.4.

Fixes included in this cumulative fix are:

  1. NullPointerException occurs when doing a DataSource lookup in a WebSphere client container after connecting to a remote ObjectGrid.
  2. Memory leak in database update feature.
  3. Randomize placement of shards so that when multiple ObjectGrids are used in an ObjectGrid configuration XML, shards are more evenly distributed.
  4. Update shutdown logic to wait for deactivate invocations on ShardEvents ObjectGridListeners to return before removing replicas from a primary shard that is stopping.
  5. Update promotion logic when a replica is becoming primary to fix the small timing window where the new primary thinks it needs to vote to rollback before it is completely available as a primary.

Install the cumulative fix listed below.
