>> i want shutdown and startup scripts. because i want to do it automated.
It is already done for you via dbstart and dbshut scripts supplied by oracle along with oracle installation.
Those are available in $ORACLE_HOME/bin.
Edit the oratab file and add appropriate entries.
All these are also said in documentation.
>> i find some scripts but i am unable to understand.
Post those here. Someone would be happy to explain them.

Again, search the board for startup/shutdown/oratab.
There are many many examples.

Hi i got this script in the net.

#!/sbin/sh
# Start/stop Oracle database(s) found in /var/opt/oracle/oratab
# NOTE that tns listener must start AFTER this script (S98tns start)
# and stop BEFORE (K20tns stop) this script.

case "$1" in
'start')
su oracle -c "/oracle/app/oracle/product/8.1.6/bin/dbstart"
;;
'stop')
su oracle -c "/oracle/app/oracle/product/8.1.6/bin/dbshut"
;;
*)
echo "Usage: $0 { start | stop }"
exit 1
;;
esac
exit 0

can any one explain me above block

i wrote one script file like this

vi shutdown.sql
set echo off
set feed off
spool shutdown.sh
select 'sqlplus "/ as sysdba"' from dual;
select 'shut immediate' from dual;
spool off;

then i got shutdown.sh file
at $sh shutdown.sh
when i tried to execute this one two things are happening
1) i am connectiong to as sysdba
2) database is not shutting down.

why? can any one explain this concept.

First bunch of code just calls the dbshut/dbstart i was talking earlier.

>> i wrote one script file like this ....
These scripts seems to be an overkill and makes less sense.
You are selecting the (sql)commands,spooling them and running
against shell.
Instead you can directly do it a shell script

oracle@mutation#somescript
Connected.
Database closed.
Database dismounted.
ORACLE instance shut down.
--
-- these are the contents. By default 
-- oracle database identified by ORACLE_SID will be shutdown.
--
oracle@mutation#cat somescript
sqlplus -s /nolog <<EOF
connect / as sysdba
shutdown immediate
exit;
EOF

As said before, you DO NOT NEED all this.
dbstart/dbshut scripts will do that for you.

yes
>>mutation ---------database name
My servername
>>somescript---------my script
just a script. you can call it anything.
>>where i have to run this statement oracle@mutation#somescript.
This is not a statement.
I just wrote an script called 'somescript' and executed it.
>>plese could you please send me sample script
The one i posted is the sample script.
Understand the concepts and Write your own. Else, you will end up
in above state. Totally confused Smile

.
Again, there is NO NEED for a seperated script.
The scripts dbstart and dbshut are already available in $ORACLE_HOME/bin.
Just edit your oratab file to add entries.
