Connect as sysdba [message #58455]

Hi,

1. I connect in OS(Unix) as user Tornado, then I can connect on my database as sysdba like this :

$sqlplus /nolog
sqlplus>connect / as sysdba;
Connected

So, if someone get my Tornado password he can connect on database as sysdba. How can I prevent this!

2. I would like to create a script for shutdown and startup database. How can I hide password in script:
sqlplus user/password
shutdown immediate

Where can I get a cold backup script?

Thanks

first,
NO user should be allowed to access oracle directly in OS in the server,  exept ORACLE user in DBA group.
and
if your password is compromised (for ORACLE account or any account!), you cannot help anything.

2. there is already a prewritten script supplied by oracle.
$ORACLE_HOME/bin/dbstart-- will start the databases
$ORACLE_HOME/bin/dbshut-- will stop the databases
to make use of these, just edit your oratab file and make changes accordingly.
by defualt these scripts are executed by os user ORACLE.
therefore, no password is required.

Set up the correct environment before using setting up the cron for your backups, start or stop the database.

An entry in the oratab will help while bringing down the server itself, so that there is clean shutdon and startup.

Make use of the orapasswd file in your scripts.
