Starting a queue manager

You start a queue manager by issuing a START QMGR command. However, you cannot successfully use the START command unless you have appropriate authority. See the WebSphere MQ for z/OS System Setup Guide for information about WebSphere MQ security. Figure 3 shows examples of the START command. (Remember that you must prefix a WebSphere MQ command with a command prefix string (CPF).)

See the WebSphere MQ Script (MQSC) Command Reference manual for information about the syntax of the START QMGR command.

You cannot run the queue manager as a batch job or start it using a z/OS command START. These methods are likely to start an address space for WebSphere MQ that then ends abnormally. Nor can you start a queue manager from the CSQUTIL utility program or a similar user application.

You can, however, start a queue manager from an APF-authorized program by passing a START QMGR command to the z/OS MGCRE (SVC 34) service.

If you are using queue-sharing groups, the associated DB2(R) systems and RRS should be active when you start the queue manager.
