Hi, we're having trouble when our application tries to use its Queue Manager. We're using MQSeries 5.3 (base product, no CSD) on HP-UX 11i. Just today, we "migrated" the machine to a more powerful one, but I think something happened during the move...I checked the kernel parameters and they are at or above the IBM recommendations. Is there a way I can clean up the shared memory and semaphores? I'd like to shut everything down and "clean up", and try again...

AMQ6119: An internal WebSphere MQ error has occurred ('13 - Permission denied' from bind.)
EXPLANATION:
MQ detected an unexpected error when calling the operating system. The MQ errorrecording routine has been called.
ACTION:
Use the standard facilities supplied with your system to record the problem
identifier, and to save the generated output files. Contact your IBM support center. Do not discard these files until the problem has been resolved.

I killed that process (it was creating HUGE error log files!) but here is the top of the FDC file:

Try ipcs to show the inter-process shared memory and semaphores.
On solaris, ipcsrm could be used do the cleanup based on identifiers. I think similar command exists on HPUX |

The problem was with directory permissions!
Our UNIX team had moved all of the filesystems over to a new machine, but the permissions got changed somehow...most of the directories under /var/mqm and /opt/mqm were missing group write permissions. So a few well-placed
statements solved the problem.
Also, there was one file (/var/mqm/conv/table/cssid.tbl) that on the "good" system was owned by mqm, but on the new system was owned by root. I asked them to change this as well so I don't know if it mattered. |

Actually, the /var/mqm and /opt/mqm permissions were only part of the problem. The REAL problem was that some of the system objects of the QM were damaged. I stopped the QM, did a
and started the QM. Then I tested it using our application and it was successful and did not cause 2.1 GB FDC files to get generated! |
