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.

Why don't you try it? There is this phenomenal Unix IDE called "vi"

Here's another idea.  Expand on it and modify as needed.

   COUNT=1
   while [ $COUNT -le 8 ]; do
  ## The first jobs command is to clear out any "jobs completed"
messages.
  jobs > /dev/null
  if [ -z "`jobs`" ]; then break; fi
  sleep 30
  COUNT=$(( $COUNT + 1 ))
   done
   jobs > /dev/null
   echo "SLEPT $COUNT times" >> "$LOG_FILE"

   ## Kill any remaining jobs.
   for JOB_NUMBER in `jobs | sed 's/\([^0-9]*\)\([1-9][0-9]*\)\(.*\)/\2/'`;
do
  kill %${JOB_NUMBER}
  echo "killed job number $JOB_NUMBER" >> "$LOG_FILE"
   done

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?

I know that bash has "wait" built in. It works like this:
GODOT=`ps -fu $LOGNAME|grep sqlplus|grep -v PID|perl -e 'while (<>)
[EMAIL PROTECTED] /\s+/; print "$A[1] "}'`
wait $GODOT

wait/notify syntax for unix help please

2003-10-27 Thread ryan_oracle 
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?
