Original question.

I have max-proc-per-user set to default 64.... I want to change this to 512,
others in my area do not want me to use dxkerneltuner (they have never used
it and don't know if it will force a reboot) they want me to edit the
sysconfigtab... I convinced them that its safer to use sysconfigdb, now here
is my predicament... I don't know syntax even after reading the man page I am
more confused... what is the name in the sysconfigtab of
max-proc-per-user... or does anyone have this memorised? Sorry if this
seems basic but I just converted from being Sun admin to a Tru64 admin on Jan
10th...

the numbers were incredible.

The common approach is what I wanted to do originally run dxkerneltuner.
There were other helpful examples of how to use sysconfigdb. Below is one
such example.


put the following in a file:

proc:
         max-proc-per-user = 512

Say the file is called XXX. Then type

# sysconfigdb -f XXX -a proc

- or, if "proc" already exists, and you wish to overwrite:

# sysconfigdb -f XXX -u proc

- or, if "proc" already exists, and you wish to merge:

# sysconfigdb -f XXX -m proc


Note that "sysconfigdb -f XXX -u proc" will remove old values from the proc
section of sysconfigdb, "sysconfigdb -f XXX -m proc" merges them - but the
"proc" section must already exists. If it doesn't exist, you need to use
the "-a" option. To check first, try:

# sysconfigdb -l proc

I plan to stick to my guns and run dxkerneltuner and then on Sunday when the
system is rebooted the changes will take.

If I run into too much opposition I will use the example above given by
Gavin.


Thanks again to everyone who replied once again this list has proven its
usefulness!
