Ping

Ping is useful in determining whether the communication link and the two message channel agents that make up a message channel are functioning across all interfaces.

Ping makes no use of transmission queues, but it does invoke some user exit programs. If any error conditions are encountered, error messages are issued.

To use ping, we can issue the MQSC command PING CHANNEL. On z/OS and i5/OS, we can also use the panel interface to select this option.

On UNIX, i5/OS, and Windows, we can also use the MQSC command PING QMGR to test whether the queue manager is responsive to commands.
