DSNM005I IMS/TM RESOLVE INDOUBT PROTOCOL PROBLEM WITH SUBSYSTEM subsystem-name

Explanation

The specified subsystem has protocol incompatibilities with IMS TM. The Db2 resolve indoubt process received an unknown or invalid recovery request (RRE) from IMS TM. The request was rejected by Db2 and kept by IMS TM.
subsystem-name
The name of the subsystem.
All DSNM messages are sent to the IMS master terminal operator (MTO) and to the appropriate MVS console.

System action

The connection between the Db2 and IMS TM subsystems remains active, and applications can access Db2 resources.

Operator response

Notify the system programmer.

System programmer response

Call IBM® Support after extracting from the IMS TM log the IMS TM attachment facility snap records (code X'5501FE') using the IMS TM utility DFSERA10.

These records contain the complete request from IMS TM to Db2, the request type is at offset X'01C', this is a four-character identifier which should contain any of the following words:

  • 'SHOW'
  • 'IDBT'
  • 'COMM'
  • 'ABRT'

If the IMS TM recovery request (RRE) found in the log is an invalid one, (not 'COMM' or 'ABRT'), you may manually delete it using the IMS/TM/CHANGE SUBSYS RESET command after consulting with the IBM Software Support.

If the IMS TM request is a valid one (abort or commit), you must find the action that IMS TM performed for that RRE by locating the X'3730' (commit) or X'3801' (abort) record in the IMS TM log and perform the same action under Db2 by using the -RECOVER INDOUBT command.

Problem determination

Recovery information is available on the Db2 log and IMS log to assist in the resolution of the problem. For each indoubt work unit, an IMS TM attachment facility snap record (code X'5501FE') is written to the IMS TM log.
