Hi
I am working on a script to check whether the queue manager is running.
Is there any way to check whether the specific queue manager is running?
thanks in advance |

knowing a pid is USELESS
It CANNOT tell you reliably whether the qmgr is active.
dspmq tells you precisely that.
As has been said here more than once before, if you'd bothered to search. |

Also, you asked "Is there any way to check whether the specific queue manager is running? "
So why are you complaining that "this just shows whether it is running... "?
Please don't reinvent the wheel.
Buy a monitoring solution. Implement it. Enjoy your life.

More accurately, dspmq shows that the qmgr believes it is running. I'd guess that the original post is asking how to determine if the qmgr is doing productive work for the end-user.
That is what Jeff is suggesting when he recommends "the wheel" that has already been invented - a monitoring tool. Tivoli, TMON, MQEnterprise, others are already in "wheel" status. |

You could also ping the queue manager
Here is a sample shell script
#
echo "ping qmgr" | runmqsc ABCD
# pingresult will be 0 on success and non-zero on error
if [ $pingresult -ne 0 ]
then
echo "QManager ABCD is not active $host for $dt " |

I would be curious to know if the original post-er has had a bad experience with dspmq? I ask because, although dspmq only shows you if the queue manager thinks it's running, I have never had a situation where dspmq displayed a "running" status but was not functioning.
This is a topic in my shop right now, so I thought I would ask....

The HA support pack uses the MQSC Ping.

dspmq didn't exist when the HA packages were originally written. These days, I think it would be the preferred choice, unless you want to get more sophisticated in checking the health, eg by putting a real msg to a loopback queue/channel and looking for the return.
dspmq is effectively doing an MQCONN (not exactly, but close) so it's pretty reliable. PING is slightly heavier processing, but it does exercise a bit more of the qmgr codepath than dspmq so it's avoiding a very hypothetical situation of the qmgr failing in such a way as to still leave internal control blocks usable.
The only issue I have with dspmq is that its responses are translated text. Easy to deal with on Unix, but not so easy on Windows. PING QMGR doesn't have that problem.
(Some people also think that what's written in qmstatus.ini is helpful for telling if the qmgr is running - they're wrong.) |
