Hi,

1) Edit the .cshrc file and insert the parameter for oracle environment (sid,base,home ...)

2) Create a file in /etc/rc0.d called KA0dbora
and in that file specify the Oracle startup script :
su - $ORA_OWNER -c "$ORA_HOME/bin/dbstart"
su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrstart"

Create a file in /etc/rc2.d called S99dbora and in that file specify the Oralce shutdown script :
su - $ORA_OWNER -c "$ORA_HOME/bin/dbshut"
su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrshut"
