Hi. I need to do a staged shutdown of a queue manager.
Stage 1 is to stop messages new being sent to the queue manager.
Stage 2 is for the local apps to finish processing the data.
Stage 3 is to shut down the queue manager.
All the queues are unique so a suspend wont prevent the messages being sent.
I just want to confirm if the following steps sound right.
1) Manualy stop the CLUSRCVR channels
2) Wait for all queues to empty
3) endmqm
I guess start up would be the reverse
1) strmqm
2) manually start the CLUSRCVR channels.
Does anyone else have any other suggestions.
Cheers

This is how I would do it too.

Assuming you are working on a Unix Platform and the MQManager you are shutting down is the only one on the Server, once the endmqm completes, as root I would do the following:
| Code: |
# ipcs | grep mqm
m 524297 0x0014a804 --rw-rw-rw- mqm mqm
m 393226 0x00146008 --rw-rw---- mqm mqm
s 1966092 0x0014b80a --ra-ra---- mqm mqm
s 131085 0x0014a013 --ra-ra-ra- mqm mqm
# ipcrm -m 524297 -m 393226
# ipcrm -s 19066092 -s 131085
|
m = shared memory segment
s = semaphore
If there are multiple MQManagers on the server use the following:
| Code: |
amqiclen -m MQMgrName -vix
|
Usage: ./amqiclen {-c | -x} -c = check -x = destroy
[-m <qmgr> | -s] -m = queue manager. -s = system subpool
[-p <prefix>] qmgrs directory Prefix (/var/mqm)
[-q] queue manager subpool
[-i] IPCC subpool
[-o] persistent queue manager subpool
[-t] trace control
[-F] Force (deleted active segments)
[-v] verbose
[-h] headings
[-d] display remaining resources
The options in detail are:
-c: check IPC only, do not remove
-x: remove IPC. Only IPC owned by mqm is removed.
Note that these options are mutually exclusive; one or the other must be
selected.
During a graceful shutdown this is not always necessary but I usually do it anyway just to ensure that the MQManager gets a clean start.

Problem? Well OK if you say so....
But then I guess Windows 2000/NT has enough problems without having to worry about shared memory.

Well, it IS handicapped by running on an inferior operating system 
I saw a comment from a Microsoft engineer once, on the stability of an experimental version of Windows, "We're seeing uptimes of weeks, sometimes months, crazy numbers"
Except if you work on a Unix platform, where the yearly reboot is an unnecessary ritual |

Months , that is crazy talk. I wonder if the Microsoft Servers that stay up that long running LongBow have an application loaded on them...
