Hi Mike,

If you really must run this script as different user instead of as oraweb, then I would recommended saving:

#!/bin/sh
owsctl stop
owsctl stop -nodemgr
exit 0

and:

#!/bin/sh
owsctl start -nodemgr &
owsctl start
exit 0

as scripts, say /scripts/a.sh and /scripts/b.sh.

You may then run these scripts like this:

#!/bin/sh
su - oraweb -c "/scripts/a.sh"
kill -9 `pgrep oraweb`
su - oraweb -c "/scripts/b.sh"
exit 0

The general syntax is su - userid -c "command"

or in this case su - oraweb -c "owsctl stop"

consider making the series of commands a script and calling the script via the su command.

... and I would beat someone over the head with a baseball bat for using a kill -9 routinely.

kill -9 `pgrep oraweb`

The correct procedure is to kill -15 ${PID}, kill -1 ${PID}, kill -2 ${PID}, kill -3 ${PID}, kill -11 ${PID}, and finally and only if necessary, kill -9 ${PID} ---- in that order and doing a kill -0 ${PID} between each command and then testing the result; if 0, the process still exists. Doing a kill -9 can leave temporary files, shared memory, and other resources dangling because no cleanup is possible.

Also, pgrep is not a standard command so you may need to craft a substitute.
