Hi,

I am getting the following errors:
------------------
AMQ7469: Transactions rolled back to release log space.

EXPLANATION:
The log space for the queue manager is becoming full. One or more long-running
transactions have been rolled back to release log space so that the queue
manager can continue to process requests.
ACTION:
Try to ensure that the duration of your transactions is not excessive. Consider
increasing the size of the log to allow transactions to last longer before the
log starts to become full.\
--------
AMQ9511: Messages cannot be put to a queue

EXPLANATION:
The attempt to put messages to queue 'EDIPITS01.DEAD.LETTER.Q' on queue manager
'EDIPITS01' failed with reason code 2003.
ACTION:
Ensure that the required queue is available and operational. ------------

when I created the Queue manager I haven't specified # log files it took default # log files...later i updated qmgrs qm.ini file..still I am getting these errors...do I need to restart the Qmgr..or is there any other way...

Thanks in advance,
Chandra.

I think a restart is necessary.

If you change the # of primary or secondary logs, the QM must be restarted and even then the effect may not be immediate.

If you change the Log Buffer pages, the QM must be restarted.

You cannot change Log File size (LogPageSize) or type of logging (circular vs linear). These are set only at crtmqm time.

I am currently struggling with a similar issue. My log files seem to be at the default of 4m each. I am currently running 55 primary and 8 secondary (the limit). How large can I make each log file?. I know I would need to recreate the qmgr. I am currently running WMQ 5.3 on AIX 4.3.3.

You can make each log file up to 16,384. So that would be 16364 x 4096 = 67,108,864 bytes.

But you can only do this if you delete your queue manager, and then when you are recreating it, specify the larger size.

crtmqm –lc –lf 16384 –lp 55 –ls 8 QMNAME

This will take quite a while (plus 5 minutes), as the system allocates all this log space (55 x 67,108,864 = about 3.5 GIG).

Peter,

Thanks...


Do i have to specify it during the crtmqm or will it use mqs.ini ?

Also, does this seem feasible to build my log system this size (to me this is huge) to accomodate long running transactions or have the application folks figure out how to do intermediate commits to relieve log space.

you have to do it at crtmqm, since that is when MQ allocates the space on the hard drive. Changing the ini file will make it LOOK like you have made bigger logs, but I am sure if you go a nd check your logs after making this type of change, you will find the size is still the same as when you created the QM.

I would do both. There is no reason an app should need that much log space under normal conditions, in 99.999999% of the the cases. And as such it should be coded to insure that it never does.

On the other hand, 3.5 gig is not really that big nowadays. I would be surprised if you were dealing with a server without that much space available just for MQ logs (don't forget to add in the space needed for the secondaries). Go ahead and create the log files as big as possible. It cant hurt.
