Hi,
On our Dead letter queue, curdepth reports depth=2, but if you read or browse the queue there is not message on the queue?
Can someone help me understand this? Also, if there is a solution to "sync" the queue it would be helpful.
We are running on AIX 6100-06, and MQ 7.1.0.3.
curdepth command:
echo "display ql(dead_letter_queue) curdepth" | runmqsc QMANAGERX

The messages are uncommitted, i.e. the application which put them there did it inside a unit of work & didn't issue a commit.
This is 1 good reason why applications shouldn't use the queue manager's dead letter queue.

Uncommitted messages count towards depth but are unavailable to browse or get. What is the UNCOM count, if any?
EDIT: And you're back-level on maintenance.

Thanks for the quick response!
The command..
| Code: |
echo "display qstatus(dead_letter_queue) UNCOM" | runmqsc QMANAGERX
|
..does indicated uncommitted messages:
| Code: |
AMQ8450: Display queue status details.
QUEUE(dead_letter_queue) TYPE(QUEUE)
CURDEPTH(2) UNCOM(YES)
|
The messages has been there for days, what (good) options do I have for cleaning up?

Your first action should be the steps given here. There is (presumably) a reason these messages were dead lettered and it might be a good idea to find out why before flushing them.
Also your best good option for clearing off is to get whatever put them to commit them & clear them off in the traditional manner. If they've been there for the length of time you indicate, that's sounding like it's not going to happen.
