In this example, MANAGER01 is the name of the queue manager. If you are not sure the name of the queue manager, use the dspmq command to display the queue managers. This assumes that the "mqm" users .bash_profile has been updated to have PATH=$PATH:<root installation directory>/bin.

You will probably first want to issue the display topic command to get the topic string.

echo "display topic ('updates') TOPICSTR" | runmqsc MANAGER01

Something like this should be returned.

AMQ8754I: Display topic status details.
   TOPICSTR(event/updates)

To display the status of the "updates" topic.

echo "display tpstatus ('event/updates')" | runmqsc MANAGER01

Following is an example of what will be displayed.
