Error Subject Name (-ERN)

Use the Error Subject Name adapter command (-ERN) to specify the subject to which a message is re-posted in the event of a map failure.


-ERN subject_name

Option: Description
subject_name: This is the TIBCO Rendezvous subject name for error messages.

If the message is not capable of being re-sent, a warning message is published to the specified error subject name. The error subject name specified with this command cannot be shared across input and output map cards, although the same subject name might be used in multiple input cards or multiple output cards.

Re-posted error messages are non-certified (reliable) messages. The initial map failure creates an adapter-generated error message with the -ERN-specified subject name and the following content: Map failed. Message to follow.

The message is then re-sent. If that re-posting is unsuccessful for any reason, a second error message with the -ERN-specified subject name is created with the following content: Message resend failure.

Map cards are processed in sequence; therefore, an input or output card using the Error Subject Name adapter command (-ERN) should be the first map card defined. If the -ERN map card follows a map card that causes a map failure, the -ERN map card is not invoked to re-send the message.

Note: The Error Subject Name adapter command (-ERN) is valid only on the TIBCO Rendezvous messaging system.
