RE: RE: wait/notify syntax for unix help please
There's no problem with waiting after the process has already finished,
you'll just get a non-zero return code the wait but evrything will still
work fine.

if you attemp to wait after the process is complete, will it cause a
problem? say the PID no longer exists when you issue wait?

I don't know about Solaris but on HP-UX and AIX you can do:
run_sql_1
run_sql_2
wait
This will wait until both have finished.
Re a specific PID $! will return you PID of the last child process and
then
you can wait on that PID. Looks something like:
run_sql_1
run_sql_2
PID_WAIT=$!
wait ${PID_WAIT}

I need to parallelize some sql operations and Im running them from unix
scripts.
I want to spawn off a few in the background from a master script, then
have
the master script 'wait' for them to finish. Ive done this in Java and
with
dbms_alert, but I cant dig up the syntax to do this with korn shell on
solaris.
Also, if I want to wait for a specific PID, how do I get the PID of the
thread I want to wait for?
so I have
nohup run_sql
wait(on previous nohup)
then to use notify, I just use 'notify()' inside the script right?
