kctune -v nproc

They are kernel parameters.

nproc is the maximum number of process on the system.

As are the others, and to change these settings you need to know how to 'tune' a system.

Hi,
All these are kernel parameters.
These parameters can be tuned, with particular formula, they are having interdependence.

To check and tune these parameters u can use command line and SAM
#kctune | grep -i kernel_parameters

Refer below links which will explain in brief

Hi,

#man nproc

will tell you everything, what to do, how to do , who can do , when to do ...

#kctune nproc=value is the command to change that.

NPROC & KCTUNE:

NPROC = NPROC is the kernel parameter, which controlling maximum number of simultaneous processes for all users.

nproc - limits the number of processes allowed to exist simultaneously

To check and tune these parameters we can use below command:
# kctune | grep -i kernel_parameters

kctune - manage kernel tunable parameters

# kctune

When we get below message in syslog:

kthread: table is full

 Then we are not able to telnet or SSH, and unable to  access from console.

To set a value use below command:

# kctune nproc=Any value
