Check links using Ping

Use the MQSC command PING CHANNEL to exchange a fixed data message with the remote end.

Ping 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 can only be used if the channel is not currently active.

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

The result of the message exchange is presented as Ping complete or an error message.

Ping with LU 6.2

When Ping is invoked, by default no user ID or password flows to the receiving end. If user ID and password are required, they can be created at the initiating end in the channel definition. If a password is entered into the channel definition, it is encrypted by IBM MQ before being saved. It is then decrypted before flowing across the conversation.
