Using the CSQUTIL utility for IBM MQ for z/OS

The CSQUTIL utility program is provided with IBM® MQ for z/OS® to help you perform backup, restoration, and reorganization tasks, and to issue commands and process object definitions.

About this task

Use this utility program to invoke the following functions. For example, you can issue commands from a sequential data set using the COMMAND function of the CSQUTIL utility. This function transfers the commands, as messages, to the system-command input queue and waits for the response, which is printed together with the original commands in SYSPRINT.

For more information about the CSQUTIL utility program, see IBM MQ utility program (CSQUTIL).

• COMMAND

  Use this function to issue MQSC commands, to record object definitions, and to make client-channel definition files.
