shut_db () {
ssh ${USER}@${SERVER} ${DBCOMM} << EOF
shutdown abort
startup restrict
shutdown immediate
EOF"

return $?
}

What is the error that you are getting? No way to suggest fixes unless we get that detail. Also, can you feed input to 'ssh' that way? Perhaps you should copy over a script that does what you are doing into /tmp on the remote system and then just execute the script through ssh.
