APAR status

  • Closed as program error.

Error description

  • On zOS it is possible to specify a connection token to help
serialize multiple connections to the same queue
manager/queue so that only 1 application at a time
with the same connection can connect. The MQInput
node should gracefully handle the error when a connection is
refused because a MQRC_CONN_TAG_IN_USE return code
is received and sleep an appropriate amount of time before
re-trying the connect.
Currently the MQInput node is treating this as an error and
logging an error message:

+BIP2678E (Msg 2/2) MQxxBRK DEFAULT 74 FAILED TO MAKE A SERVER
CONNECTION TO QUEUE MANAGER 'MQxx': MQCC=2; MQRC=2271.

Local fix

  • NA

Problem summary

  • ****************************************************************
USERS AFFECTED:
All users of IBM Integration Bus V10 on z/OS who use the z/OS
serialization token option of an MQInput Node.


Platforms affected:

CONNECTION TO QUEUE MANAGER 'MQxx': MQCC=2; MQRC=2271.

Problem conclusion

  • MQRC_CONN_TAG_IN_USE errors are now handled appropriately.
A BIP2656 information message is issued and the MQInput node
waits before re-trying the connect.
