Hi MQ Experts.
I want to enable performance events on my 5.3 Qmgrs .
I am running following version of MQ :
| Quote: |
Name: WebSphere MQ
Version: 530.12 CSD12 CMVC level: p530-12-L051208 BuildType: IKAP - (Production) |
I had created queue as mentioned in documentation and enabled performance events .
| Quote: |
ALTER QMGR PERFMEV(ENABLED)
DEFINE QLOCAL('MYQUEUE1') MAXDEPTH(1000) QDPMAXEV(DISABLED) QDEPTHHI(2) QDPHIEV(ENABLED) QDEPTHLO(2) QDPLOEV(DISABLED)) |
As per my understanding , the Performance event will be generated by QM and event will be lying in SYSTEM Queue SYSTEM.ADMIN.PERFM.EVENT when curr depth of queue reaches to 20 (2% of MAXDEPTH) .
But this is not happening !!
Am I doing any thing wrong here? Does MQ 5.3 support Performance events. Because I found it working in MQ 6. 0 Solaris box.
Thanks in advance ..

Change you QDEPTHLO watermark and try again. From experience (with that version of WMQ) I've seen strange results where HI/LO settings were close - the LO event was received before the HI.

Check whether the queue has IPPROC > 1, which would indicate something has the queue open and is removing the messages.

| As the book says, Low Depth events are caused when the depth DECREASES across the threshold. So if you're just putting messages to the queue you will not see them. You have to start getting the messages. The purpose of the Low Depth event is to show that a previously busy queue is now "healthy" - it's not an early warning that the queue might be filling. |

Of course it is.
Does the queue on which you're testing have any messages on it? The event will only fire once the number of messages goes through the threshold. In your example, where the threshold is set to 20 messages, it will fire when the 20th message is put. It won't fire if the queue has 200 messages on it when the threshold is set, even though it exceeds the threshold.

This is all explained in the WMQ Monitoring manual, "Understanding depth events."

Just trying to underline the relevant part, as it were.

Have you tried restarting the qmgr after the alter?
I seem to recall having to do that but this could be just age creeping up on me.  |

Performance event attributes do not require qmgr restart. But, like chicken soup, it couldn't hurt.

Sorry for delayed reply .
I found that command server must be running for PCF to work .
In MQ 5 Command server does not start with strmqm . We have to start them manually using strmqcsv.
Where as In MQ6.0 Command server starts when starting queue manager |
