APAR status

  • Closed as program error.

Error description

  • If a client channel is attempted to be started, while the
    configured amount of MaxActiveChannels is already running, an
    additional entry in status STARTING will be listed in the
    DIS CHS output until the queue manager has been restarted.
    

Local fix

Problem summary

  • The channel status entry was allocated before it was verified
    that MaxActiveChannels has not been reached yet. However it was
    not cleaned up after should that have been the case already.
    

Problem conclusion

  • Product has been changed to verify that a slot is available
    and MaxActiveChannels has not been reached yet before allocating
    and trying to start the new channel instance.
