How to add bcvmap_size_factor as kernel parameters?

[Ricky_4]

Hi Everyone,

We compared kernel parameters of development and production server. And found out production server has no "bcvmap_size_factor" entry on its kernel parameters. That's why we could not put a value in that kernel parameter name. How can we add this kernel parameter name in prod server? What is the purpose of this?

Both servers is HPUX version 11.11.

Your assitance is a big help for us.

Thanks.

Ricky

This kernel parameter doesn't seem familiar to me. Isn't it provided by a loadable module ? In that case, could you verify that the two servers are running the same modules ?

Fred

Hi Fred,

Thanks for the reply.

How could I verify the modules from the two servers?

Ricky,

Check the patch levels on the two machines. The one that does have bcvmap_size_factor probably has PHKL_29527 or PHKL_30516 applied. The bcvmap_size_factor tunable was introduced via one or the other of these patches and applying one or the other to the machine that doesn't show this tunable will add it.

use kmtune to compare....for an individual parm:

kmtune -q bcvmap_size_factor
