How to start sap on linux while booting?

Question

Hi all,
I want to start and stop SAP automatically when the system starts or is stopped.
In earlier Suse (SLES 9) releases there was a script sapr3 in /etc/init.d which could be used for it, when the file /etc/sysconfig/sapr3 was filled correctly.
In newer releases (SLES 10) there is no such script (besides boot.sapconf, which is uesd to set the sap parameters).
Does anybody know how to start and stop sap systems using the init.d mechanism?
Thank you for you help.
Best regards
Christian

I do understand, that the function does no longer exist. But how to "create your own".
If I were to create one I'd use something along the following lines...
#! /bin/sh
# SAP startup script - sapstart
# chkconfig sapstart on - to enable on startup
# Replace SAPEXE,ADMUSR and SLOG below with correct values
### BEGIN INIT INFO
# Provides: sapstart
# Required-Start: $network $syslog $remote_fs $time
# X-UnitedLinux-Should-Start:
# Required-Stop:
# Default-Start: 3 5
# Default-Stop: 0 1 2 6
# Short-Description: Start SAP
# Description: Startup of SAP
### END INIT INFO
. /etc/rc.status
PATH=/sbin:/bin:/usr/sbin:/usr/bin; export PATH
SAPEXE=/sapmnt/DEV/exe
ADMUSR=devadm
SLOG=/var/log/saplog
SHELL=/bin/csh
# Reset status of this service
rc_reset
case "$1" in
    start)
     echo -n "Starting SAP.. "
     su -s $SHELL -l $ADMUSR -c $SAPEXE/startsap >> $SLOG &
     # Remember status and be verbose
     rc_status -v
    stop)
     echo -n "Please ensure SAP is cleanly shutdown before rebooting!.. "
     # Remember status and be verbose
     rc_status -v
     echo "Usage: $0 {start|stop}"
     exit 1
esac
rc_exit
I deliberately left out 'stop' for obvious reasons, don't forget to create the log file.
Untested so use at your own risk !
