Supported Delivery Modes and Undeliverable Message Actions

 

This appendix describes the valid combinations for the delivery and uma arguments in each BEA MessageQ supported environment.

The delivery argument uses the PDEL_MODE_sn_dip format where:

• sn is one of the following sender notification codes:

  WF-Wait for completion

  AK-Asynchronous acknowledgment

  NN-No notification

• dip is one of the following delivery interest point codes:

  ACK-Read from target queue and explicitly acknowledged using the pams_confirm_msg service. ACK can also be an implicit acknowledgement sent after the second pams_get_msg call by the receiving application.

  CONF-Delivered from the DQF and explicitly confirmed using the pams_confirm_msg service

  DEQ-Read from the target queue

  DQF-Stored in the destination queue file

  MEM-Stored in the target queue

  SAF-Stored in the store and forward file

  Note: If temporary queues are used, deleted, and reused quickly, it is possible in isolated cases for an implicit ACK response from a previous temporary queue to be placed on the new temporary queue.

The uma argument uses the PDEL_UMA_xxx format where xxx is one of the following codes:

DISC-Discard

DISCL-Discard after logging (Open VMS only)

DLJ-Dead letter journal

DLQ-Dead letter queue

RTS-Return to sender

SAF-Store and forward

Note: On UNIX and Windows NT systems, the DISCL UMA performs the same as the DISC UMA, discarding the message without logging the event.

Delivery Mode and UMA Cross-Reference

Table A-1 uses the following key for delivery mode support:

X--Supported
.--Not supported
S--Available if supported by message ser
