Collect WebSphere MQ MustGather data to solve channel problems on HP NonStop Server

Resolving The Problem

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

• What channel problem did you observe on the system?
• What time did the channel problem start and when did it stop?
• Which queue managers, channels, remote queues and transmission queues are involved?

Step 1: Generate Data

If the channel 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 channel problem is happening.



2. Generate MQ trace simultaneously at the other end of the channel, whether a remote queue manager, a native client application, or a JMS or Java client:
   
   
   • Linux and UNIX
   • Windows
   • IBM i
   • Java and JMS client

   • z/OS CHIN trace
   • z/VSE
   • HP Integrity NonStop Server
   • HP OpenVMS

Step 2: Collect Data

1. Record the MQ version and maintenance level.



2. Record the operating system version and maintenance level.



3. On the sending side, use runmqsc to record your queues, channels and channel status information. If any command gives an error, carry on with the others:

DISPLAY QMGR ALL
DISPLAY QLOCAL(*) ALL
DISPLAY QALIAS(*) ALL
DISPLAY QREMOTE(*) ALL
DISPLAY CHANNEL(*) ALL
DISPLAY CHSTATUS(*) ALL




4. On the receiving side, use runmqsc to record your queues, channels and channel status information. If any command gives an erorr, carry on with the others:

DISPLAY QMGR ALL
DISPLAY QLOCAL(*) ALL
DISPLAY CHANNEL(*) ALL
DISPLAY CHSTATUS(*) ALL




5. Use the sdcp script to package your files for IBM, including files containing the output from the commands listed in Step 1 and 2.

Step 3: Send Data to IBM

1. Send your data to the IBM ECuRep repository by email to websphere_support@ecurep.ibm.com, or by standard or secure HTTP or FTP.



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.




A good description of the problem and the data is the most important information you can provide to IBM. Please do not send data without providing a description!



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.
