You can use standard DLH program that comes with WMQ or write your own. Messages in DLQ will have one additional header called Dead Letter HEader. You can write a simple program to read these messages and do whatever you plan to do with them. There is a chapter in System Administration Guide on DLH.

You can write a simple rule file test.rul file containing a script like:
| Code: |
inputq('SYSTEM.DEAD.LETTER.QUEUE') inputqm('TESTQM') WAIT(NO)
DESTQ('APPL1.DEST.Q') ACTION(FWD) FWDQ('APPL1.SRC.Q') FWDQM(TESTQM) HEADER(NO) |
and then run the command runmqdlq like:
| Code: |
runmqdlq < test.rul
|
This will move the messages intended for 'APPL1.DEST.Q' from DLQ to the Q named 'APPL1.SRC.Q'

Anywhere runmqdlq can see it...... 
Seriously, depends how you're scheduling runmqdlq to run. The rules file is just an input file, piped in as you normally would.

You could also use MQMON (SupportPac MO71), which is able, to translate the DLQ-Header.

| You can also browse the dead-letter queue with amqsbcg or the MQ Explorer. |

But with amqsbcg it is hard to read!
And for MQ Explorer you need a local MQ server installation, MQMON only requires the MQ client.
Additionally MQMON is also able, to read the DLQ on z/OS (if there is a Client Attachement Feature installed).

Nope. MQ Explorer can execute from a non-server platform.
Your original post asked how to read the dead-letter queue. What do you want to accomplish by reading it? What exactly are you looking for? This may help us posters guide you in a better direction. |

MQ Explorer for MQ version 5 must have a MQ server installation.
MQ Explorer for MQ version 6 does not need a MQ server installation, but you only get it with a server installation. I was told, that it should be possible, to remove the server afterwards - but this is not supported  .
Hopefulls it runs.

Downlod the free trial version of WMQ v6 (server). Install it, selecting only the client and MQexplorer.
Nothing to delete and also the MQexplorer does not expire after 90 days (so I believe anyway).
Same applies to the full version - you do not have to install the queue manager (or server) to get MQExplorer to work. Just choose the custom install and select the bits you want.
V6 explorer can adminster V5 queue managers (but not z/OS)

Mea culpa for assuming you were asking about MQ V6. |
