Error description

  • If a member of a CoreGroup is in a problematic state which
    cannot be determined as up or down,
    services that rely on a defined state of the entire CoreGroup
    have to wait until the problematic server is either up or down.
    Getting the warning below as:
    
    CWRLS0030W: Waiting for HAManager to activate recovery
    processing...
    
    Although distributed transaction recovery is not enabled at all
    (it is also not enabled by default), there should be no such
    check of the CoreGroup status. Problematic server would be
    ignored and the server process could start up.

    ****************************************************************
    When an application server running in a cluster starts the
    recovery log service registers with the HA Manager regardless
    of whether the cluster has been configured to enable
    failover of transaction log recovery.  This is a defensive
    measure so that if failover is later enabled but only part
    of the cluster is restarted the HA Manager will already have
    all cluster members registered.
    If the environment is experiencing networking problems then
    this registration step may not be possible until the network
    issues have been resolved, however the application server will
    not start until registration has been successfully performed
    and hence not be available to process work.
    

Problem conclusion

  • When the application server is not a member of a cluster that
    has failover of transaction log recovery enabled it is not
    necessary for the recovery log service to register
    with the HA Manager.  Such behaviour does however provide a
    safe-guard in the event that failover is later enabled and
    only a partial restart of the cluster occurs.
    
    In this scenario the default behaviour remains unchanged but the
    following JVM System property can be set to a value of 'true'
    so that the recovery log service does not register with the
    HA Manager:

    The fix for this APAR is currently targeted for inclusion in
    fix packs 7.0.0.31, 8.0.0.8 and 8.5.5.2 .  Please refer to the
