  1. Log on using the root user ID.
  2. Run the following command: rpm -qa | grep MQSeriesClient. If the following output is displayed, then WebSphere MQ Client is already installed on the Linux system: MQSeriesClient- version.

How do you increase Maxdepth in MQ?

To increase the size of a message queue, complete the following steps: Monitor the queue depth with the WebSphere MQ Explorer. See the documentation for the MAXDEPTH parameter in WebSphere MQ queue properties. If the message queue fills up with messages, adjust the value of the MAXDEPTH parameter.

How do I check my MQ settings?

If you normally start your queue managers as the mqm user, you should switch to mqm and run mqconfig there. If other members of the mqm group (and perhaps root) also start queue managers, all those members should all run mqconfig, to ensure that their limits are suitable for IBM MQ.

Is IBM MQ and IBM WebSphere MQ same?

IBM® MQ (formerly known as WebSphere MQ and MQSeries) is robust messaging middleware that simplifies and accelerates the integration of different applications and business data across multiple platforms on-premise and in the cloud. It supports a wide range of APIs and programming languages.
