Collect IBM MQ MustGather data to security problems on z/OS

Technote (troubleshooting)


An IBM MQ queue manager is experiencing a problem with security and you need to collect MustGather data to find a solution.


The instructions apply only to IBM MQ V8.0, 7.1, and 7.0.1 on z/OS. Refer to the IBM MQ Read First page for instructions on other operating systems :

Resolving the problem

Please answer these questions about the problem and then follow the steps below:

  • What sort of security problem did you observe on the system?
  • What time and date did the security problem start ?
  • Are only queue managers (queues) involved, or also channels, etc. ?

Step 1: Generate Data

If the security problem is reproducible or is happening right now, generate data to provide more information about the problem:

  1. Generate a trace of the queue manager while the security problem is happening.

  2. The following diagnostics may also be required :

Step 2: Prepare Data to Send

  1. Preparatory steps apply to dumps, traces and joblogs.

  2. Use TRSMAIN/AMATERSE utility before uploading to ECUREP and ensure PMR#, B/O#, Country# is specified.

    1. Joblogs may be emailed if not too large.

  3. FTP must be done in BINARY mode only.

    Use Email to provide summary information

    1. Email address :

      Subject line must include PMR#, B/O#, Country#


    2. See message CSQY000I for z/OS MQ level and for distributed MQ see here.

    3. Record the operating system version and maintenance level on any subsystems involved.

    4. Note the resources, profiles, classes and which subsystem security settings are active.

Step 3: Send Data to IBM

  1. Send your data to the IBM ECuRep repository After confirmation, emails may be sent to

  2. While the data is transferring, send an email or use the IBM Service Request tool to update your PMR with your description of the problem and of the data you are sending.

  3. Contact your country representative if you need to speak to an IBM technical support representative, or in the US call 1-800-IBM-SERV. Refer to the IBM Software Support Handbook for more information on working with IBM.
