A poison message is a message sent by the client to the server that has failed a specified number of times. When a poison message is received, the message processor shuts down. You can manage the poison message by popping it out of the queue or redirecting it to another message store.

Before you begin:

If you want to redirect a poison message to a specific message store, that store needs to be already defined. For instructions to define a message, see Creating a Message Store.

To handle a poison message, follow the steps below:

  1. In the Main tab, click Message Processors to open the Manage Message Processors page. When a message processor is deactivated after receiving a poison message, it is assigned the Inactive status, and a View Message link is displayed for it as shown below.

  2. To view the message payload, click View Message.

  3. If you want to pop the message out of the queue, click Pop Message. A message appears for you to confirm whether you want to proceed. Click Yes. Once you confirm, you are redirected to the Manage Message Processors page. If you want to reactivate the message processor, click Activate.
  4. If you want to redirect the messages, click Redirect Message. A dialog box named Select a store to redirect the message opens. In the Redirect to field, select the message processor you want to redirect the message to.

  4. If you want to redirect the messages, click Redirect Message. A dialog box named Select a store to redirect the message opens. In the Redirect to field, select the message processor you want to redirect the message to. Then click Redirect.

    Only the pre-defined message stores appear in the list.

  5. If there are more then one poison messages, repeat steps 2-4 to pop them out of the queue and redirect tham as required. Once all the poison messages are handled, the following message is displayed instead of a message payload when you click View Message for the message processor (i.e., step 2).
