Problem summary


    

  • ****************************************************************
* USERS AFFECTED:  Users of IBM WebSphere Application Server   *
*                  utilizing the Cluster's rippleStart         *
*                  operation                                   *
****************************************************************
* PROBLEM DESCRIPTION: Cluster ripple start fails when any     *
*                      member's start fails                    *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
When a server start fails during a ripple start operation, the
ripple start process lacks exception handling allowing it to
move
on to the next server in the list. Instead, the entire ripple
start operation is aborted at that point.

    



Problem conclusion


    

  • Ripple start now tolerates failed server starts, logs any
exception to FFDC, and continues with the next cluster member.

The fix for this APAR is targeted for inclusion in fix packs
