Canceling QAnywhere messages

Canceling a QAnywhere message puts the message into a canceled state before it is transmitted. With the default delete rules of the QAnywhere Agent, canceled messages are eventually deleted from the message store. Canceling a QAnywhere message fails if the message is already in a final state, or if it has been transmitted to the central messaging server.

The following procedures describe how to cancel QAnywhere messages.

Note

You cannot cancel a message using the QAnywhere SQL API.
