Not to get into the nuts and bolts of triggering on depth that has been suggested by several already, it is not immediately obvious that your programmers MUST reset the trigger on depth before terminating each time or the trigger will turn OFF and never start your app again. This is something small but it has driven many good programmers to distraction.
Alan -----Original Message----- From: MQSeries List [mailto:[EMAIL PROTECTED] On Behalf Of Dye, Janet E Sent: Thursday, November 18, 2004 11:28 AM To: [EMAIL PROTECTED] Subject: BATCH messages advice requested Currently, most messages received on our mainframe qmgr are destined to CICS and are triggered 'on first' . We are in the process of putting in a new application that will receive large volumes (50,000+) of batch messages from a vendor. The messages will come in at different times of the day, sometimes being just a few messages at a time and other times being the large volume I just mentioned. The developer wants to schedule a job that runs different times throughout the day to process these messages. My concern is that since volume is unpredictable and as more applications do this, it will become impossible to plan disk space to hold the number of messages that could potentially be in the queues any point in time. My feeling is that I need to create a policy that messages are removed from a queue upon arrival or at least upon arrival of a certain volume. I have suggested to the developer that we will need to set up a trigger to trigger 'on first' or on 'depth', and they code the program to do a MQGET with a wait of a minute or so. I am getting a little resistance to this in that they are concerned about the job being triggered a lot, and they would prefer to just schedule it to run every hour or so. I am interested to know what policy, if any, other shops have for this situation.
