[Version 5.0.1 and later]Interoperating with the Scheduler service

Before you begin

The WebSphere Application Server Enterprise Edition Scheduler Version 5.0 service has several interoperability problems that affect how the Scheduler behaves in a clustered environment with mixed WebSphere versions and/or mixed platforms. Specifically, there are two issues that cause interoperability problems:

  1. The EJB HomeHandle format has changed between the Versions 5.0 and 5.0.1 of the product. See interim fix PQ72184 or the Interoperability section of the Version 5.0.1 Release Notes.
  2. The asynchronous beans serialization mechanism has changed between Versions 5.0 and 5.0.1 of the product. See interim fix PQ72742 or the asynchronous beans section of the Version 5.0.1 Release Notes.

To avoid problems interoperating between Version 5.0 and 5.0.1 and or higher, all Version 5.0 scheduler service customers must first apply the Version 5.0 fix packs associated with interim fixes PQ72184 and PQ72742 and remove all scheduled tasks that were created prior to applying these fix packs.

Be aware that removing all scheduled tasks involves removing data from your scheduler service databases. Follow these procedures for each scheduler instance defined on the affected server.

Steps for this task

  1. Recreate all scheduler tasks.
    Use this method if you wish to programmatically recreate your scheduled tasks.
  2. Delete all scheduler tasks.
    Use this method to remove all of your Scheduler tasks and recreate them manually.
  3. Recreate all scheduler tables.
    Use this method to drop and recreate the scheduler tables.
