13=Ping

Use the Ping option to exchange a fixed data message with the remote end. This gives some confidence to the system supervisor that the link 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 WebSphere MQ for iSeries, it is run with the USERID of the user requesting the function, whereas the normal way that a channel program is run is for the QMQM USERID to be taken for channel programs. The USERID flows to the receiving side and it must be valid on the receiving end for the LU 6.2 conversation to be allocated.
