How to start Oracle database automatically when after SunSolaris is being re-booted?
TIA,
Greg

This works on one of the servers running Oracle - you may have to change it to suit your needs.

#!/bin/sh
ORA_HOME=/u01/app/oracle/product/8.0.5
if [ ! -f $ORA_HOME/bin/dbstart -o ! -d $ORA_HOME ]
then
echo "Oracle startup: annot start"
exit
fi
case "$1" in
  'start')
# start Oracle databases
su - oracle -c $ORA_HOME/bin/dbstart
su - oracle -c "$ORA_HOME/bin/lsnrctl start "
;;
'stop')
# stop Oracle databases
su - oracle -c "$ORA_HOME/bin/lsnrctl stop "
su - oracle -c $ORA_HOME/bin/dbshut
;;
esac

And if you want to start and stop the other services such as the SNMP agent, OEM, and the web services:

# Start the Intelligent Agent
if [ -f $ORA_HOME/bin/agentctl ]; then           
    su - $ORA_OWNER -c "$ORA_HOME/bin/agentctl start"
else
    su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl dbsnmp_start"
fi

# Start Management Server
if [ -f $ORA_HOME/bin/oemctl ]; then
    su - $ORA_OWNER -c "$ORA_HOME/bin/oemctl start oms"
fi

# Start HTTP Server
if [ -f $ORA_HOME/Apache/Apache/bin/apachectl ]; then
    su - $ORA_OWNER -c "$ORA_HOME/Apache/Apache/bin/apachectl start"
fi

# Stop HTTP Server
if [ -f $ORA_HOME/Apache/Apache/bin/apachectl ]; then
    su - $ORA_OWNER -c "$ORA_HOME/Apache/Apache/bin/apachectl stop"
fi
# Stop Management Server
if [ -f $ORA_HOME/bin/oemctl ]; then
    su - $ORA_OWNER -c "$ORA_HOME/bin/oemctl stop oms sysman/<password>"
fi
# Stop the Intelligent Agent
if [ -f $ORA_HOME/bin/agentctl ]; then
    su - $ORA_OWNER -c "$ORA_HOME/bin/agentctl stop"
else
    su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl dbsnmp_stop"
fi

Tested on Sun Solaris:

#!/bin/sh

  if [ -d /export/home/oracle/OracleStartScripts ] ; then
        :
  else
        mkdir /export/home/oracle/OracleStartScripts
        chown oracle:oinstall /export/home/oracle/OracleStartScripts
  fi
