Automating Shutdown and Startup Oracle10g Database

October 31, 2009 3 comments

To automate database startup and shutdown by using the dbstart and dbshut scripts:

1. Log in as the root user.

2. Edit the oratab file for your platform.

once the instance is created, edit the “/etc/oratab” file setting the restart flag for each instance to ‘Y’.

To open the file, use one of the following commands:

$ vi /etc/oratab

3. Create a file called dbora in /etc/init.d .

$vi /etc/init.d/dbora
!/bin/bash

The lines to start and stop the listener can be removed under Oracle 10g release 2, as the dbstart command includes an automatic start of the listener.

4. Change the group of the dbora file to the OSDBA group (typically dba), and set the permissions to 750:

$ chgrp dba dbora
$ chmod 750 dbora

5. Add dbora in checkcofig:

    $ chkconfig  --add dbora
    $ chkconfig  --level 345 dbora on
