Your Thoughts on MQ Series Kernel Param Requirements

[Alzhy]

These are the kernel params being requested:

a) msqmnb – increase to 65,535
b) maxfiles - increase to 10,000
c) maxfiles_lim - increase to 10,000

Anyone have MQ Series installed on 11.11 machines and have these kernel params set the same?

[John Kittel]

For MQ 5.3, my settings for these params already met or exceeded the recommendations. The recommendations were:

msgmnb = 4096, maxfiles = 1024, maxfiles_lim - no recommended setting.

I guess you are looking at installing a later version of MQ, and the recommendations have changed.

Nelson,

If you are to install an application and they have requested the kernel params. in the installation guide, then I would have to assume that they are needed. I recently queried with the same kind of reservations, but was assured that if requested then probably needed. No need to worry.

I set msgmnb to the same value... because DB/2 demands that (msgmax is 65535 accordingly).
The recommended value is 4096.
maxfiles and maxfiles_lim depend on your application load.
The recommended value is 1024.

If you don't want to waste resources set the maxfiles* parameters to, lets say, the half (5000) and monitor the usage.

My 2 cents,
Armin
