I have a situation where my client would like for me to remove the first 23 messages from a queue. I know that there USED to be some sort of destructive get command (amqsget?) that would allow you to specify the number of messages to get. It may have even been a destructive browse (amqsbrowse?)
I'm currently in a Windows environment, running MQ version 6.0.24. I am comfortable using either the command line or GUI, but I am simply not having any luck finding a way to PARTIALLY clear the queue... it seems to be all or nothing.
Any help would be greatly appreciated.
Thanks!

AFAIK amqsget (which isn't a command, but a sample application) has always destructively read all the messages from a queue as supplied by IBM; if you encountered a modified version then that might do anything.

A destructive browse is a contradiction in terms, but amqsbcg still exists (again a sample not a command)

You could use something like qload to unload the entire queue, delete the messages from the file, then reload the queue.
Or modify amqsget to take a parameter of how many message to read. Easy enough change.

Also, if you have any monitoring tools such as BMC Patrol, you can look at and delete message one by one or a number of message at one time or copy or move to another queue. |

Unfortunately, this environment is still in the DEV/TEST phase, so no monitoring tools are implimented yet. I just seem to recall that there was a single command (or sample application) that would perform this, and allow a flag to designate a range of numbers to utilize... I'm just hoping that it's not an "all or nothing" scenario where this is concerned.
Thanks!

MO71 can unload a queue with 'purge' and a range of messages can be chosen (23 specified as '0..22').
See the unload option against a queue - you can unload (purge) to a file and then discard the file. |

Thank you Zpat! It's not quite what I remember, but it's effective, non-the-less!
Actually, if you simply browse the queues, there's a DELETE button in there that will allow you to select as many items as you want, and get rid of them that way as well.
Again, thank you!

MO71 does almost everything.
The author Paul Clarke is presenting a session on support pacs at the next MQ user group at Hursley UK, July 1st.

| You can also use rfhutil to browse or destructive get for each of a msg in the queue. |

I think, kodiakk is looking for the selective messages in a queue.
as he said ".. remove the first 23 messages.." or suppose he wants to pick the message(s) from the middle of the queue.
MO71 is the better option, i would say.

I suspect that kodiakk is actually thinking of ma01, not m071.
or a dead simple script on amqsget/amqsgetc. |

Yes, you guys are correct. I am looking to selectively remove items from a queue, either 1-23, or 213-279, something like that. At one point, a number of years ago, I am pretty sure that my teamlead presented us with a simple command (or sample application) that allowed a "destructive browse" or a "get" where we could designate a range of messages.
Anyway, the MO71 support pack did do the trick, and I appreciate all of the feedback.
Thanks guys!

Let us know, if you'd come to know about that command/application some how.

we are using the MQMON utility to remove the message from nth position.
i think it is MO72 only?
Cheers,
