AIX

Pederabo
Just clarifying-

So you are agreeing with Shockneck and saying that using the SRC would handle this problem better than an /etc/inittab entry, which is what I did at first?

You agree with the solution I gave below using mkssys as as a safe alternative?

I already had runaway processes blow up on this box to the danger of livelihood and limb, would like to hear a few ayes from the crew on this new different approach before proceeding.

thanx!

I don't know AIX, SRC, or mkssys well enough to comment on that.

Does anyone else agree with my mkssys solution?

I don't know the app but the mkssys definition looks good. Give it a try.

Okay I created the dprdaemon subsystem with this command:

mkssys -p /dplogs/dpr_daemon -s dprdaemon -u 0 -a "-D" -e /dev/null -i /dev/null -o /dev/null -R -S -Q -f 9 -n 15

I specifically put in '-Q' to state that multiple instances of this program are not allowed, although it is the default anyway.

It responded that it had created the subsystem.

When I do a

lssrc -a | grep dpr

I see it as 'inoperative'.
dprdaemon inoperative


When I:

startsrc -s dprdaemon

I get:
0513-059 The dprdaemon Subsystem has been started. Subsystem PID is 831714.

All good.


BUT........
I immediately have 3 instances/processes running on the box, not 1:


# ps -ef | grep dpr
root 454674 1 0 15:42:04 - 0:00 /usr/bin/perl /dplogs/dpr/dpr_daemon -D
root 831720 1 0 15:42:04 - 0:00 /usr/bin/perl /dplogs/dpr/dpr_daemon -D
root 839896 1 0 15:42:04 - 0:00 /usr/bin/perl /dplogs/dpr/dpr_daemon -D


Also, when I do:

# lssrc -a | grep dpr

I see:

dprdaemon inoperative


Very strange!
Registering the subsystem seems to have worked. But why would activating the subsystem create 3 instances, and then the subsystem show as 'inoperative' ?

Puzzling.

What does
# odmget -q subsysname=dprdaemon SRCsubsys
return?
