Hi,
We are on MQ version 7.0.1 and OS: solaris 10 x86.
We tried to increase the primary and secondary logs under "/var/mqm/qmgrs/<qmgrname>" in qm.ini file,
ExitPath:
ExitsDefaultPath=/var/mqm/exits/
ExitsDefaultPath64=/var/mqm/exits64/
#* *#
#* *#
Log:
LogPrimaryFiles=15
LogSecondaryFiles=10
LogFilePages=1024
LogType=CIRCULAR
LogBufferPages=0
LogPath=/var/mqm/log/<QMgrName/
LogWriteIntegrity=TripleWrite
Service:
Name=AuthorizationService
EntryPoints=13
ServiceComponent:
Service=AuthorizationService
Name=MQSeries.UNIX.auth.service
Module=/opt/mqm/lib64/amqzfu
ComponentDataSize=0
Channels:
MaxChannels=200
MQIBindType=FASTPATH
But I still see the primary logs as only 3 under /var/mqm/log/<qmgrname>/active.
When I tried to create a new qmgr called TESTQMGR, it is creating with the logfile size of 4MB each. In version 7.0.1, it should be 16MB.
Is anything different on Solaris 10 x86?.
Thanks |

LogPrimaryFiles
The value is examined when the queue manager is created or started. You can change it after the queue manager has been created. However, a change in the value is not effective until the queue manager is restarted, and the effect might not be immediate. |
Regarding the Log File size, what does your mqs.ini file say?

You are right Peter. When we change the # of logs in qm.ini file and restart the qmgr, the effect is not immediate and the extra (increased logs) are created as needed basis. It is not similar to crtmqm -lp 10 -ls 5 QM1. I was expecting this behavior when I bumped up the # of logs in qm.ini file.
Regarding the log file size:
This queue manager was created when we were at version 6 and later migrated/ upgraded to version 7.0.1.
In this case the mqs.ini file shows:
| Quote: |
LogDefaults:
LogPrimaryFiles=3
LogSecondaryFiles=2
LogFilePages=1024
LogType=CIRCULAR
LogBufferPages=0
LogDefaultPath=/var/mqm/log
QueueManager: |
When we have this in mqs.ini file, even we create a new queue manager it is creating the queue manager logs with 4 MB as log file pages set to 1024 in mqs.ini file.
Where as on a server which is installed with version 7 directly (not upgraded from version 6), its mqs.ini file doesn't contain the primary| secondar logs info and log file pages info.
It is as shown below:

LogDefaults:
LogDefaultPath=/var/mqm/log
QueueManager: |
I was looking into the version 7.0.1 documentation and it is saying that version 7 queue manager creates 16MB of each log file. This is not entirely true when you upgrade from version 6. If you can adjust the mqs.ini file to match the version 7 of MQ's mqs.ini, then YES.
Thanks for the info. |
