Maximum number of processes kernel parameter
Hi,

Is there a maximum number of processes kernel parameter in AIX.

Solaris has max_nprocs,
HP-UX has nproc,

I can only find max user process (maxuproc) for AIX.

Thanks,

Wilson.

Sorry.

If it's not in:
Code:
smitty chgsys

Or:
Code:
lsattr -E -l sys0

I don't think it's possible. At all

Yes It's not available within AIX
MAXUPRCDefines the maximum number of user processes.

Issue this command to determine the current setting for the number of processes
Code:
# lsattr -E -l sys0 | grep maxuproc

This command to increase MAXUPRC to 100
Code:
# chdev -l sys0 -a maxuproc=100

actually the equivalent on AIX is ncargs

the default on AIX 5.3 is 6 4k pages what usually is too small, on AIX 6.1 the default changed to 256 which is twice as much as the max value was on AIX 5.3

Hope that helps
