Process Federation Server known limitations

Make sure that you are aware of the following known issues and limitations when using IBM® Process Federation Server.

BPEL indexer

The following types of BPEL tasks are supported by the indexer:
  • To-do tasks
  • Collaboration tasks
  • Subtasks
  • Follow-on tasks
The following types of BPEL tasks are not supported by the indexer:
  • Administration tasks
  • Task templates
  • Invocation tasks
  • Parallel routing tasks
The following types of BPEL task events are not supported by the indexer:
  • Task escalations
  • Process suspension

Only query properties are indexed as business data. Input, output, fault messages, custom properties, and fast custom properties are not indexed.

Deferred deletion of process instance related tasks from the Process Federation Server index

As Process Federation Server does not index process instances, when you delete a process instance with Process Inspector, the corresponding tasks might not be immediately deleted from the Process Federation Server index. Those tasks will be deleted the next time that the SYNC_TASK_DELETE operation is run by the Process Federation Server BPD indexer, as specified by the synchronizeTasksDeleteInterval property of the indexers.

Saved Searches

If a saved search result is sorted on a business data field that is defined as a Long for one process and as a Double for another, the sort is performed as if the business data field type was String.
