Hi
MQ 6.0.2.x had a list of LogDefaults in the mqsi.ini file as shown below. The MQ 7.1 mqsi.ini file has much fewer LogDefaults.
Do I need to add to the MQ 7.1 mqsi.ini LogDefaults so the log size will be produced as expected? I cannot find any info on this change - my logs in 7.1 are now 4 times the size they were in 6.0.2.x and TOO Big!
MQ 6.0.2.x
LogDefaults:
LogPrimaryFiles=3
LogSecondaryFiles=2
LogFilePages=1024
LogType=CIRCULAR
LogBufferPages=0
LogDefaultPath=/var/mqm/log
MQ 7.1
LogDefaults:
LogDefaultPath=/var/mqm/log
thanks |

Please post the ini log values from a 7.1 qmgr. I don't have access to 7.1 yet.

I see the LogFilePages to be 4096 on my newly created V7.1 Qmgrs.
when you change the default in the explorer, it is added to the mqs.ini

Hi,
Thank you all for your replies. (mqs.ini files from MQ 7.1 and 6.x are shown below.)
I do not see where the log file page size is set in MQ 7.1, or most of the other mqs.ini defaults. In MQ 6.x it was set in the mqs.ini file (default 1024), in MQ 7.1 there is no default log file page size value in the mqs.ini file. So, where is it set PRIOR to creating the queue manager?
The MQ 7.1 mqs.ini file is shown below, along with an mqs.ini file from MQ 6.x. Also, the logs created from each of the MQ versions are shown below. Again, the default for MQ 6.x is 1024 page size, and the default for MQ 7.1 is set in an unknown location and is much larger so that the logs are 4 times the size of those created in MQ 6.x.
Background: We are doing a server upgrade - going from Solaris and MQ 6.0.2.10 (live) to Linux (not currently live). We started with MQ 7.0.1 on Linux for a couple of weeks in EXP and then went to 7.1 after it came out in November. So, I do not have any 7.0.1 info to compare with MQ 7.1.

The V6.0 Info Centre states: "...In WebSphere MQ for UNIX systems, the default number of log file pages is 1024, giving a log file size of 4 MB...".
The V7.0.1 Info Centre states: "...In WebSphere MQ for UNIX systems, the default number of log file pages is 4096, giving a log file size of 16 MB...".
The V7.1 Info Centre states: "...In WebSphere MQ for UNIX and Linux systems, the default number of log file pages is 4096, giving a log file size of 16 MB...".
So, no change between V7.x but by a factor of four between V6.0 and V7.x. I suspect that is for good reason, but would need Hursley to provide what that is.

Hi,
Thank you exerk for compiling the information.
Perhaps Hursley could have somone update the info on the "Changes from Websphere MQ version 6.0 to Websphere MQ version 7.1" in the MQ 7 InfoCenter. The change in the default log file size is not included in this listing.
Thank you all! |

Fasted way to get the info center updated is to click on the little 'feedback' button.
it's interesting to note that this change is not documented in the migration section of the 7.1 info center, nor in the migration section of the 7.0 info center either.... |
