| 8. Remove all shared memory and semaphores owned by the mqm user ID and mqm group, or use the amqiclen command and pipe in the mqs.ini file, or restart the machine. Shared resources can be identified using the ipcs command, and can be removed with the ipcrm command. |

To check and free any unused System V IPC resources, log on as user mqm and type:
On Solaris, HP, Linux /opt/mqm/bin/amqiclen
On AIX /usr/mqm/lib/amqiclen
This command does not report any status. However, if some WebSphere MQ-allocated resources could not be freed because they were still in use, the return code is nonzero. |

| How about the link at the top of the page - "documentation"? You're interested in the one called "Library Home Page". |

amqiclen has its own usage statement, and here is some extra detail on the utility:
It is installed in /opt/mqm/bin (/usr/mqm/bin on AIX), with permissions 555, owner/group mqm:mqm.
Therefore to be able to run it you do not need to be logged on as a user with any mqm permissions.
However, since the IPC resouces are keyed from files in the MQ directory trees you will need to be logged on as a user in the mqm group to check IPC, and as mqm to destroy IPC.
Here is the new amqiclen usage statement:
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.
-m QMGR: check/remove IPC on qmgr QMGR
-s: check/remove IPC in the system subpool, i.e. the qmgr @SYSTEM
-p prefix: search for qmgr data in directory prefix (default /var/mqm)
-q: IPC in qmgr subpool only, i.e. shm/sem dirs in the qmgrs/QMGR dir
-i: IPC in IPCC subpool only, i.e. shm/sem dirs in the qmgrs/QMGR/@ipcc dir
-o: IPC in qmpersist subpool only, i.e. shm/sem dirs in the qmgrs/QMGR/@qmpersist dir directory. The directories are shmem esem isem msem ssem
-t: Trace control shm/sem, keyed from /var/mqm/errors
-F: Force removal. Normal operation is not to remove IPC which is in use. This is determined by checking the processes using a semaphore, or the number of processes attached to a shared memory segment. This flag bypasses these checks
-v: Where appropriate, print output showing the progress of the utility
-h: Print headings in the output
-d: Run the commands ipcs -m and ipcs -s
Further notes
In the above I refer to "IPC .. keyed from files..". This means that the key of a semaphore set or shared memory segment is derived from the inode of a file or directory in the MQ directory tree.
Note that the -m | -s flags are not mandatory. If both flags are omitted, amqiclen checks (removes) IPC from all directories found in the prefix/qmgrs
The arguments conform to the usual UNIX rules for parsing the command line. The options may be specified separately, e.g. amqiclen -c -v -h -t -m QMGR, or they may be concatenated until an option is reached that requires a further argument, e.g. amqiclen -cvhtmQMGR has the same effect.
This applies to 5.3 CSD07 or later. |

Hi,
For Solaris, it is located in /opt/mqm/bin . All MQ executables are in this directory.
Regards,
Roger Lacroix

| I got the usage of amqiclen script. Thanks everybody for your help. I also want to know the description of other scripts which is under /opt/mqm/bin. Please let me know where I can find those information. Also is there any pdf which has all these info? |

| I'd suggest looking in the Systems Admin manual. It is a multi-platform manual not a platform specific one. |
