Has anyone seen this error after upgrading to v7.0.1 on AIX? The CPU usage starts to go up when the FDC is cut..

Hi Mike,
Are you talking about File descriptors? I see the current value for nonfiles is set to 2k which is the same for mqm. According to Quick Begginer's Guide, mqm should be set to 10K.
Thanks,
John |

Hi Mike,
We've increased the process limit to 10K as per docs, set the resource limits to unlimited, set the env_variable and bounced the qmgrs. So now just waiting to see if the issue will come back. I'll keep you posted.
Thanks for all your help Mike, appreciate it! |

Don't miss this page http://www.ibm.com/support/docview.wss?uid=swg1IY99425
You have a good level of MQ code as per that doc. Check the AIX level, APARs. Check you are using EXTSHM as appropriate (details covered at that page.. search thru for EXTSHM to get all the info). |

Thanks mvic, already looked at this. We downloaded the shmtest script
http://www-01.ibm.com/support/docview.wss?uid=swg21298595
which revealed that we were not setting/using EXTSHM properly so we made the necessary adjustments there as well. It takes about a week for the issue to resurface (at least that's what we've seen so far) so we'll just wait and see what happens.
Appreciate your input! |

I believe you need to bounce the box for that to take effect. Bouncing the qmgr won't change the process limit AFAIK.
Although for the resource limit, setting it and bouncing the qmgr might work.
Have fun
