Hi, We have been asked to justify our decision to let receiving channel message retry count and interval parameters (mrrty and mrtmr) take their default values. These allow (non z/OS) MQ to retry message put failures up to 10 times, one second apart, before writing the message to the dead letter queue. For the obvious reasons (no such queue, expired temporary dynamic queue), there seems little point to the retries, and reasonable concern over possible backlogs following a transient hold-up, e.g. network hitch.
To the question - Is anyone aware of sound reasons for keeping the default values as they are? Is there a reasonably common condition that causes a temporary inability to deliver valid messages, that is overcome via the retries? I find myself wondering about MQ internal checkpointing, or lock activity type stuff. My thanks to all who take the time to read this, especially if they share their experience with us all.
