MSMQ-Life of Messages...

[Raj]

After I create some messages ... and after a while those messages
automatically disappear from the queue. What is the lifetime of messages in a
queue? Is it possible to persist messages in a queue as long as it is read??

Thank you

Regards
Raj

You need to read up on configuring message queues.
When you create one you configure stuff like that.

Hi

The lifetime of a message is set in two ways
1 A global default in the registry or A
2 Within the application by the developer

Default is 4 days to be delivered to a queue and unlimited for how long a message stays in a queue once delivered

Note that restarting the MSMQ service on the queue host will purge any EXPRESS messages

But the messages I have created yesterday and today have disappeared. Only
messages created few seconds ago are there in the queue!

Any clues?

Thank you

Hi Raj,

1 Enable "Negative Source Journaling".
http://technet.microsoft.com/en-us/library/cc739818(WS.10).aspx
If a message is deleted by MSMQ (because of a timeout, for example) it will
appear in the sender's Dead Letter Queue or Transactional Dead Letter Queue
(as appropriate).

2 Enable "Target Journaling".
http://technet.microsoft.com/en-us/library/cc739507(WS.10).aspx
If a message has been read by an application it will appear in the
destination's journal queue.
