Solving IBM WebSphere MQ problems

Initially, run the installation verification program. You might also have to use the trace facility.

If a program does not complete successfully, run the installation verification program, and follow the advice given in the diagnostic messages. This program is described in Verifying the IBM WebSphere MQ classes for Java installation.

If the problems continue and you need to contact the IBM service team, you might be asked to turn on the trace facility. Do this as shown in the following example.

To trace the MQIVP program:
  • Create a com.ibm.mq.commonservices properties file (see Using com.ibm.mq.commonservices .
  • Enter the following command: 
    java -Dcom.ibm.mq.commonservices=commonservices_properties_file java 
-Djava.library.path=library_path MQIVP -trace
where:
  • commonservices_properties_file is the path (including the filename) to the com.ibm.mq.commonservices properties file.
  • library_path is the path to the WebSphere MQ classes for Java libraries (see The WebSphere MQ classes for Java libraries ).
