So Bruce... you trust the programmer to correctly write the application to generate the billion dollar message (and test it, maintain it, etc), but not to set persistence correctly?

The programmer must set the persistence field of the MD with one of the three persistence values. He/she should pick wisely - to meet the business requirement.
If the programmer sets the MD to non-persistent, the "default" queue attribute of PERSISTENT has no affect.
If I'm the programmer, I want my application to behave exactly the same way every time; not have it change behavior because a sysadmin (or elf) changed a queue attribute.
Trust with verification. |

One thing you need aware is the space for mq log's, and performance. When dealing with a high number of messages, you need to know what programmers are doing with persistence.
Using / not using persitence can have great impact on mq performance, depending on message load, message size, number of queues.
Regards. |
