(nice big capitalized topic you've got there  )
Please explain what you mean by "damaged" - what error messages do you see, what are the symptoms etc.
Generally speaking, if you don't have important messages in this queue, fastest solution would be to delete and re-create it; if you need the data on it, you're probably into some trouble. |

AMQ7472: Object SYSTEM.DEAD.LETTER.QUEUE, type queue damaged.
EXPLANATION:
Object SYSTEM.DEAD.LETTER.QUEUE, type queue has been marked as damaged. This
indicates that the queue manager was either unable to access the object in the
file system, or that some kind of inconsistency with the data in the object was
detected.
ACTION:
If a damaged object is detected, the action performed depends on whether the
queue manager supports media recovery and when the damage was detected. If the
queue manager does not support media recovery, you must delete the object as no
recovery is possible. If the queue manager does support media recovery and the
damage is detected during the processing performed when the queue manager is
being started, the queue manager will automatically initiate media recovery of
the object. If the queue manager supports media recovery and the damage is
detected once the queue manager has started, it may be recovered from a media
image using the rcrmqmobj command or it may be deleted.
Now , the problem is I can't do a display on this queue or view or anything , so I am not able to delete it.

One possible solution i could think of is(not 100% sure)
save the q.m (using save.qmgr)
Delete the q.m
Recreate the q.m
do runmqsc <(the saved mqd file)
that should do it.
unless it is some production box |

Did you just try to delete it without trying to display it first?

I don't think there will be any way to restore your SYSTEM.DEAD.LETTER.QUEUE unless you can restore the filesystem from a backup or delete then recreate the MQManager unless you were/are using Linear Logging.
If you use the saveqmgr tool remember to backup your objects, use the "-s" to suppress creation of SYSTEM object definitions in the output file. For example:
saveqmgr -s -m QMGRNAME -f output.file.name
Also remember to make a backup of your /var/mqm/qmgrs/QMGRNAME/qm.ini file and before you delete the existing MQManager check your active log configuration. You may need to define your log file size in the crtmqm command.

Here is what I have done in this circumstance that has worked...
This is at your own risk, but if you are going to delete the queue manager anyway otherwise who cares.
1. Stop the queue manager.
2. Find the queue in the filesystem. (All queues exist in the filesystem as files) (If you can't find it then don't even attempt this.)
3. delete it using the os (not the mq commands)
4. restart the queue manager.
5. recreate the queue.
Good luck.

| Of course, you also have the option of 'sticking your head in the sand', ignore the problem with the SYSTEM.DEAD.LETTER.QUEUE, and designate an alternate dead letter queue. |

I have done the same thing Pat did on the very rare occasion that a Q became damaged.
Who needs Linear Logging?!
