Hello,
i wrote a little script to backup all queuemanager which are running on a server using the program saveqmgr.linux. i made a cronjob runnig the script every day at the same time.
til here everthing is nice, the script is working and doing its job.
The problem i have now is, that there are lot of local queues with DEFTYPE(PERMDYN) and a name like SAVEQMGR.4F...... created everyday at the same time my script is running. Why aren't they cleaned up? On some other machines where i deployed my script, these queues do not exist...
Anybody got idea?
Thanks. |

Cleaned up is not WebSphere MQ terminology. What do you mean?

Yes. And, it seems, that saveqmgr is not finished with its dynamic queue at the precise instance that it creates the file object definition SAVEQMGR... .
Did you look for the SAVEQMGR... dynamic queue local object AFTER saveqmgr ended? What did you discover?

| yes, that's right. That is the queue which is created after running saveqmgr. on the server are about 60 of them, all created just the second my script is called. Means: script in crontab 6 o'clock... SAVEQMGR.... queue created 6:00:01... |

I understand the maintainer of saveqmgr is responsive to questions presented via the documented methods of contacting him.
Saveqmgr uses a dynamic reply queue.
If you are seeing that this queue remains in existence after you have closed saveqmgr, then something very odd is going on - perhaps your script is forcibly quitting saveqmgr when it shouldn't be.
You can not run saveqmgr without having it create this queue - unless you take your own time and effort to alter the code and recompile it to use a different queue. |

| Ok, i can follow you. but the oddest thing, the example output was done without my script. this was just executed in the command-line... is it possible to get the exit code of saveqmgr? perhaps this gives a clue... |

The source code for saveqmgr comes with it.
It acts like a standard C program that writes to stdin and stderr, and returns an integer to the shell. |

| There are also options in MQ and in saveqmgr that control whether temporary or permanent dynamic queues are used/created. |

when i type "saveqmgr -?" i don't find any option to prevent creating permdyn queues. only the option to handles already existing perndyn queues as local queues.
and in mq i can't change the option, because dynamic queues are still used from other applications than saveqmgr...
I just tried to use the -version flag because the used mq is 6.0.2... but still doesnt work the way i want. We also use mq 7 already... and on these machines there are no permdyn queues named "SAVEQMGR..." |

Please be aware (if you are not already) that flag is for saving up-level queue manager objects for down-level queue managers, e.g. a V7.0 dump to populate a V6.0 queue manager.
