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
