Bjvrn,
That would be what I'd do, sort of.
Usually I set up a script in /etc/init.d to start and stop unidata cleanly,
and then I link to it from the appropriate /etc/rc?.d directories, and for
good measure put a script in /usr/local/bin which I whack higher in the PATH
than $UDTBIN which intercepts any startud or stopud commands and pushes them
through my /etc/init.d/unidata script.
By doing this, I make a decent fist of driving any normal mechanism for
starting or stopping unidata through a single spot so I can do other useful
stuff at the same time - like write a message to syslog, or more
importantly, make sure that the current RFS archive log file has been copied
to the DR server.
If someone knows what they are doing they can always get direct access to
stopud or startud via $UDTBIN/st...ud, but it isn't often that you'd want to
do that.
The decision then is whether to put the startup for you phantoms into the
same script as the one that starts unidata, or whether to put it in a
separate /etc/init.d script and maybe link to it from a higher run level
/etc/rc?.d.
UniData commands not providing any reliable exit status is very annoying,
but it has always been that way I'm afraid. What I usually do is add an
extra capability to my /etc/init.d/unidata so that it understand not just
the start and stop commands, but also a 'status' command which will use
showud and look for a complete daemon set running to determine if it really
believes that UniData is running. I then make it exit with a known status
so in other scripts I can do:
if /etc/init.d/unidata status
then
# stuff that relies on UniData being up
else
echo "better start UniData first!"
exit 2
fi
I'd wrap something this around your phantom initiation commands, and think
hard about whether you need some way to shut your phantoms down neatly or is
it OK simply to have stopud -f kill them?
Cheers,
Ken
