13=Ping

Use the Ping option to exchange a fixed data message with the remote end.

A successful IBM MQ Ping gives some confidence to the system supervisor that the channel is available and functioning.

Ping does not involve the use of transmission queues and target queues. It uses channel definitions, the related communication link, and the network setup.

It is available from sender and server channels, only. The corresponding channel is started at the far side of the link, and performs the start-up parameter negotiation. Errors are notified normally.

The result of the message exchange is presented in the Ping panel for you, and is the returned message text, together with the time the message was sent, and the time the reply was received.

Ping with LU 6.2

When Ping is invoked in IBM MQ for IBM i, it is run with the user ID of the user requesting the function, whereas the normal way that a channel program is run is for the QMQM user ID to be taken for channel programs. The user ID flows to the receiving side and it must be valid on the receiving end for the LU 6.2 conversation to be allocated.
