I had a problem when the linear log was set. The log got full and cleaned the log. Not able to issue any MQ commands. So we killed all the MQ process and rebooted the machine and cleaned the semaphores and shared memories. This is the development box.

But still seeing very bad performance when it comapred with performance we had seen before the log got full.

is there anything else need to be cleaned? I hope i did everything but the same performance is not restored? Any help from experts?

Using linear logs did you get any of the linear log maintenance support packs like MS0L ?

You need to keep your linear logs in a separate file space / mount and archive regularly. I suggest you have enough space for 25 hours of logs.

Enjoy

Now it is changed into CIRCULAR log for testing purpose but the performance did not come back to the normal.
