Kernel Params for Multithread Processes

KPS — Tue, 09 Dec 2003 09:41:59 GMT

Hi,

I have a N-4000 running an Oracle DB on it. We seem to be having a most recent issue with multithreaded processes running and then dying within the Database.

Is there any certain Kernel Params I can look at that cover Multithreaded Processes, to try to bump up to attempt to fix this issue?

Thx,
-Ken

Check "max_thread_proc" and "nkthread"

Thanks

max_thread_proc comes to mind. It controls the maximum # of threads a process may create

Take a look at this process management Kernel parameters and compare your values (max_thread_proc, nkthread etc):

This is a good document about Kernel parameters:
