Sources from which you can issue MQSC and PCF commands on IBM MQ for z/OS

You can issue MQSC and PCF commands from the IBM® MQ for z/OS® console, the initialization input data sets, the batch utility CSQUTIL, or from authorized applications. Not all commands can be issued from all these sources.

Which MQSC and PCF commands can control each IBM MQ object

Table 1 in "Command summary for IBM MQ for z/OS" maps which MQSC and PCF commands can be used on IBM MQ for z/OS to alter, define, delete and display each IBM MQ object. See also MQSC commands reference and Using IBM MQ Programmable Command Formats.

List of sources from which commands can be issued

If you are a suitably authorized user, you can issue IBM MQ commands from the following sources:

The z/OS console or equivalent (such as SDSF/TSO).
See also Using the operations and control panels on z/OS.

Note: When using the z/OS console, you need to add /cpf to the start of a command, where cpf is the command prefix for the queue manager subsystem.
The initialization input data sets CSQINP1, CSQINP2, CSQINPT and CSQINPX.
See Initialization commands for IBM MQ for z/OS.
The z/OS master get command routine, MGCRE (SVC 34).
The IBM MQ batch utility programs such as CSQUTIL, which processes a list of commands in a sequential data set.
See Using the IBM MQ for z/OS utilities.
Suitably authorized applications, sending commands as messages to the SYSTEM.COMMAND.INPUT queue.
The application can be any of the following:
- A batch region program
- A CICS® application
- An IMS application
- A TSO application
- An application program or utility on another IBM MQ system
See Writing programs to administer IBM MQ for z/OS and Preparing sample applications for the TSO environment on z/OS.

Not all commands can be issued from all sources

Commands are classified according to where they can be issued from:

1: CSQINP1
2: CSQINP2
C: The z/OS console
R: The command server and command queue, by means of, for example, CSQUTIL, CSQINPT, CSQINPX, or authorized applications.

Within the command descriptions in MQSC commands reference, these sources are identified by the use of the characters 1, 2, C, and R in each command description. Table 2 in "Command summary for IBM MQ for z/OS" summarizes the MQSC commands and the sources from which they can be issued.
