Backout queue processing in JMS
Hi all, We recently discovered that JMS would honor the BOQUEUE and BOTHRESH parameters and set up an exception queue for one of our applications. Problem is that whenever messages are put to the exception queue, they remain uncommitted for long periods of time. Since the requeing takes place outside of application control, the developer doesn't know at what point, if at all, she can issue a commit on the exception messages. Does anyone know of a good doc that discusses backout queue processing in JMS? Or maybe you have some advice on the matter to pass along? Thanks in advance! -- T.Rob Instructions for managing your mailing list subscription are provided in the Listserv General Users Guide available at http://www.lsoft.com Archive: http://vm.akh-wien.ac.at/MQSeries.archive
