Compaq Tru64 'process' kernel parameters explained.

GOAL:

What are the Compaq Tru64 'process' kernel parameters?

FACT(s) (Environment):

Compaq Tru64 UNIX

FIX:

Maximum Number of Processes (NPROC)

The task_max keyword is based on the maxusers keyword and sets a limit on the number of processes that can be running on the system. Normally, you should modify the maxusers keyword, rather than the task_max keyword. Initially, task_max is set to the following:

1+ (20 + (8 * maxusers))

This value is not absolute. It is used to determine the size of a data structure that controls the number of user processes that can run simultaneously. Increasing the value of task_max allows more user processes to be active at the
same time. Decreasing this value limits the number of user processes.

The system displays the following message if it reaches the task_max limit:

pid: table is full

You can find the previous message in the /var/adm/messages file and in the kernel event-logging file.

The task_max kernel parameter in the param.c file is equivalent to the task_max keyword in the configuration file.

Maximum Number of User Processes (MAXPROC or MAXUP)

The maxuprc keyword defines the maximum number of processes one user can run simultaneously. A task running with superuser (SU) privilege can exceed the maxuprc limit.
