tuning message queue parameters in linux

[huskers]

hi,

I have a script which puts messages on message queue. On AIX I had the max. size of queue set to 4MB. Just wondering what is the maximum size the queue can be set to on Linux?. The defaults as as follows:

max queues system wide = 1024
max size of message (bytes) = 8192
default max size of queue (bytes) = 16384

Can anyone tell me what can be the maximum setting of the above parameters without affecting the performance of the box as I also have DB2 on it.

Thanks

Take a look at the following -

This should be in line with optimizing DB2 but I would recommend doing some follow up analysis on the system performance after you set the parameters to see if they need to be modified in your enivoment.


Cheers,
