The "correct" way to update inittab is to use the mkitab, chitab, and rmita=
b commands.
If an entry in inittab is set to run once, then rereading inittab will not =
restart the entry. You need to change the action field to respawn, save in=
ittab, and then kill the process. I think init actually rescans inittab co=
ntinually, so it should restart automatically.

As root,
nohup /usr/bin/topas -R 2>&1 >/dev/null &
works nicely for processes like this one that do not have any environment v=
ariable dependencies, but I've been watching this thread hoping for an answ=
er for how to properly update inittab and start a process that has environm=
ent variable dependencies.
For example, process schedulers like UC4 should have a consistent environme=
nt setup every time it starts up. It should not depend on /.profile or $EN=
V (usually $HOME/.kshrc or $HOME/.env) that may override settings in /etc/e=
nvironment also getty, login, and sh/ksh set environment variable. For exa=
mple, I had a COBOL runtime environment work fine until it was restarted wi=
th a missing or unknown TERM variable. It worked fine because the script w=
as started with sudo -H -b su - -c "/path/to/script start" but failed at re=
boot when init ran the script because TERM was not set. It was especially =
difficult to track down because it recognized xterm, but not vt220, so rest=
arting it from the command line had mixed results depending on which user r=
estarted it and what term type they were using. Another time a script depe=
nded on setting LOGNAME. Although this is bad practice to set LOGNAME, it =
worked fine when the script was started from a bash command line, but faile=
d at re-IPL since init used sh which called /etc/profile which has the comm=
and "readonly LOGNAME". I could also get into issues with ulimits when thi=
ngs are not started consistently by the same user.
I was wondering what the correct way to add something to inittab and/or SRC=
is. Is it appropriate to have SRC start a wrapper script? Or is there ad=
ditional overhead involved in programming something to be under SRC control=
? I'm looking at these tools because they always start processes the same =
way and do not depend on the current user's environment which is often slig=
htly different between test and production machines. I'm trying to minimiz=
e surprises when promoting code from dev, test, and prod and also at re-IPL=
time.
Also is "init q" the same as "kill -HUP 1"
Although Grace's original question seems to have been answered, it got me t=
hinking about a similar problem I have been wanting to solve.

Hi, Even,
The change I made in /etc/inittab is
change code:
xmdaily:2:once:/usr/bin/xmwlm -L 2>&1 >/dev/null # Start xmwlm daily
recording
to code:
:xmdaily:2:once:/usr/bin/xmwlm -L 2>&1 >/dev/null # Start xmwlm daily
recording topasrec:2:once:/usr/bin/topas -R 2>&1 >/dev/null # Start
topas recording
I expect run "init q" should start "topas -R", but it doesnt.
I have to reboot the system to get "topas -R" run.
This is just a test system, I need to apply it in our production system
which cant aford to be down even for a short time.
Is there anyway the new added process can run without reboot the
machine?
Thanks.
Grace
