How to start Oracle database in solaris Machine

Question

I installed Oracle database in my solaris machine. Everything went fine .. I was able to install it and test the database if it's working or not.
Something happened that made me shut down and restart the solaris machine, the problem is that Oracle is not running, so I have to start it manually, and I'm not sure how to do that ... Is there a way to start Oracle automatically once the solaris machine is started ...
I'm using the SSH Secure Shell Client to configure and install everything into the solaris machine ..

Here is the work around for starting oracle instance automatically.
1) logon the system as root user.
2) under /etc/init.d/ directory, create a file name oraclestart(name the file to what you feel comfortable). eg: /etc/init.d/oraclestart.
with the following content:
#!/bin/sh
# Created by Henry Nguyen
# Date 10/11/2005
# Script to automatic start and stop oracle instances on server
ORACLE_HOME=/export/home/oracle/product/9.2.0.1.0 (diffrent on your system)
if [ ! -f $ORACLE_HOME/bin/dbstart || ! -f $ORACLE_HOME/bin/dbshut ]; then
echo missing oracle start/stop script
exit 1
fi
case "$1" in
'start')
su - oracle -c '$ORACLE_HOME/bin/dbstart'
su - oracle -c '$ORACLE_HOME/bin/lsnrctl start'
'stop')
su - oracle -c '$ORACLE_HOME/bin/lsnrctl stop'
su - oracle -c '$ORACLE_HOME/bin/dbshut'
esac
3) create 2 soft link as following:
ln -s /etc/init.d/oraclestart /etc/rc2.d/S99oraclestart
ln -s /etc/init.d/oraclestart /etc/rc0.d/K10oraclestart
Note the S99 and K10: that are Solaris priorities to when start and stop an oracle instance and those letter must be capitalized.
Hope this will help you
