APAR status

  • Closed as program error.

Error description

  • When the MCA hosting the channel is running in the same
    CPU as a slave repository manager that is terminated,
    the channel is recreated, hence destroying the existing
    channel status.
    

Local fix

Problem summary

  • The restart logic used by a repository manager that is
    restarting following a process failure performs a delete channel
    operation in some circumstances where an automatically defined
    channel object has expired but not yet removed from the cluster
    cache.  This can result in the deletion of an automatically
    defined channel that has been forcibly stopped using STOP
    CHANNEL, and hence eligible for recreation and restart
    immediately after the recovering repository manager starts.
    

Problem conclusion

  • The delete channel operation should never be issued by a
    repository manager during recovery processing.
    

Temporary fix
