Troubleshooting
Problem
IBM MQ is not triggering an application or a channel properly, and you need to collect MustGather data to find a solution.
Environment
These instructions apply only to IBM MQ V9.0 and V8.0, and WebSphere MQ V7.5, V7.1, V7.0 and V6.0 on AIX, HP-UX, Linux, Solaris and Windows, and to IBM MQ V9.0 and V8.0, and WebSphere MQ V7.1, V7.0 and V6.0 on IBM i. 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 triggering problem did you observe on the system?
- What time did the triggering problem start and when did it stop?
- Which queue did not trigger, and which channel or processs should have been started?
Step 1: Generate Data
If the triggering problem is reproducible or is happening right now, generate data to provide more information about the problem:
- Generate a trace of the queue manager when the triggering problem occurs:
Step 2: Collect Data
- Collect data automatically with the runmqras command if you are running IBM MQ V9.0 or V8.0, or WebSphere MQ V7.5, V7.1.0.1 or later, or V7.0.1.8 or later. Be sure to collect the runmqras defs and trace sections, and to specify your PMR number:
- Alternatively, collect the MQ data manually.
- If your system has more than one MQ installation, use the setmqenv command to choose the one with the problem before proceeding:
Linux and UNIX
sh> . /path/to/mqm/bin/setmqenv -n InstallationXWindows
C:\> "C:\Program Files\IBM\MQ\bin\setmqenv" -n InstallationX - Record the MQ version and maintenance level.
- Record the operating system version and maintenance level.
- Save the MQ configuration information, for example registry keys and ini files.
- If your system has more than one MQ installation, record your MQ installation details:
Linux and UNIX
sh> dspmqinst > /tmp/dspmqinst.txtWindows
C:\> dspmqinst > %TEMP%/dspmqinst.txt - On MQ server V7.1 and later installations, use dmpmqcfg to record the queue manager configuration:
Linux and UNIX
sh> dmpmqcfg -m QMA > /tmp/QMA.config.txtWindows
C:\> dmpmqcfg -m QMA > %TEMP%\QMA.config.txtIBM i Qshell
===> /QSYS.LIB/QMQM.LIB/DMPMQCFG.PGM -m QMA > /tmp/QMA.config.txt - Otherwise, on MQ server V7.0 and earlier installations, use runmqsc to record the queue manager configuration. If any command gives an error, carry on with the others:
DISPLAY QMGR ALL
DISPLAY Q(*) ALL
DISPLAY SUB(*) ALL
DISPLAY TOPIC(*) ALL
DISPLAY CHANNEL(*) ALL
DISPLAY SERVICE(*) ALL
DISPLAY PROCESS(*) ALL
DISPLAY LISTENER(*) ALL
DISPLAY NAMELIST(*) ALL - On all MQ installations, use runmqsc to record status information from the queue manager. If any command gives an error, carry on with the others:
DISPLAY PUBSUB ALL
DISPLAY QMSTATUS ALL
DISPLAY CHSTATUS(*) ALL
DISPLAY LSSTATUS(*) ALL
DISPLAY SVSTATUS(*) ALL
DISPLAY SBSTATUS(*) ALL
DISPLAY CONN(*) TYPE(*) ALL
DISPLAY QSTATUS(*) TYPE(QUEUE) ALL
DISPLAY QSTATUS(*) TYPE(HANDLE) ALL
DISPLAY TPSTATUS('#') TYPE(PUB) ALL
DISPLAY TPSTATUS('#') TYPE(SUB) ALL
DISPLAY TPSTATUS('#') TYPE(TOPIC) ALL - Manually package your files for IBM, including files containing the output from the commands listed in Step 1 and 2.
- If your system has more than one MQ installation, use the setmqenv command to choose the one with the problem before proceeding:
Collecting runmqras output from queue manager QMA
runmqras -section defs,trace -qmlist QMA -pmrno 12345,67R,890
Step 3: Send Data to IBM
- Send your data to the IBM ECuRep repository by email to websphere_support@ecurep.ibm.com, by standard or secure HTTP or FTP. or by using the IBM Secure Diagnostic Data Upload Utility (SDDUU) Java application.
- 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.
- 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.
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!
