Does anyone use MQ Explorer to access MQ on a Tandem? Specifically, we use 5.3 MQ Explorer on Windows and have recently applied CSD03 EFIX1 on our 5.1 MQ and it's stopped working properly.
Tandem queue managers have been stopped and started only. We didn't do a dltmqm and crtmqm as part of the upgrade.
MQ Explorer is connecting via the svrconn channel as principal mqm and we can display the channels. When we try to display the queues it fails with a timeout.
The system.admin.command queue hasn't changed.
We also access MQ 5.3 on Unix and that part still works a treat.
Nothing appears in EMS and there are no FFSTs produced. Anyone got any ideas? A bit baffled by it all. IBM are on the case, but thought I'd run in past the gurus on this site too.
Any help greatly appreciated. |

If application of a CSD broke something, you should raise a PMR. Are you sure it was the CSD that broke this? (Was there anything else that was done administratively to MQ?) |

Have raised a PMR.
We were running with CSD02 with version 5.1 and all we did was run the CSD03 upgrade + the C3EFIX1. No other changes took place, which was what baffled us.
Initial suggestion from IBM is to increase a timeout parameter for MQ Explorer in the registry. That kinda makes sense to a degree as we have over 300 queues in one queue manager. However, the other queue manager only has around 100.
Currently waiting for our desktop team to do the registry update. To be continued... |

I would think that maybe there is higher efix available we are @ csd03 and the efix is c3efix3.
I use MQJexplorer myself on my PC much less troublesome! |

We went for efix1 as it was the latest at that time and it was the one our auditors were most interested in, specifically because it allowed you to better secure the Pathway environment (mqpathsec param). We've rolled out this change to all systems, with our dev box being the last to go. It's only our dev folks who use MQ Explorer, so it's only come to light now.
The security param wasn't seen as being an issue on dev, so we simply upgraded MQ having stopped all qmanagers. This seems to be the problem. We organised a copy of MQ Explorer on our own PCs and saw the same problem, i.e. display channels took quite a while but returned info. Display queues however simply timed out.
We created a new queue manager and were able to access it without any problems which suggested that perhaps there were too many queues in the dev qmgrs.
Did a saveqmgr and added the same queues into our test chap, and again, no problems.
So, the solution is to delete and re-create all queue managers if you are using MQ Explorer, despite the fact that the qmgrs themselves are working away like little sweeties.
That was the easy bit. The tricky bit is breaking it to the developers that they have to recreate their qmgrs ('cos they've done some seriously weird stuff in there!).
Thanks for the hints/suggestions. |
