This is a how to autostart the Oracle 11g R2 Database Server on CentOS 6.2. I assume you have done the following:
So, it's time to run the three installed components as Linux daemons. These components are: listener, database and enterprise manager. The main programs concerning the start and stop tasks for these components can be found at $ORACLE_HOME/bin, and they are:
- Install an Oracle-ready CentOS 6.2 Linux box
- Install the Oracle 11g R2 Database Server on the CentOS 6.2 Linux box
- Configure a network listener for Oracle 11g R2 Database Server on the CentOS 6.2 Linux box
- Create a fresh Oracle 11g R2 database on the CentOS 6.2 Linux box
So, it's time to run the three installed components as Linux daemons. These components are: listener, database and enterprise manager. The main programs concerning the start and stop tasks for these components can be found at $ORACLE_HOME/bin, and they are:
- listener: lsnrctl {start|stop|...}
- database: dbstart / dbshut
- ent. manager: emctl {start|stop|...}
- Login as the bozz user (a sudoer) in the server and create the archive /etc/init.d/oracle with the following content:
- First, ensure that the init.d script can be executed manually:
- Use chkconfig to register the init.d script on runlevels 3, 4 and 5:
then verify if is marked as on in the runleves 3, 4 and 5:$ sudo chkconfig --add oracle
$ chkconfig --list oracle
oracle 0:off 1:off 2:off 3:on 4:on 5:on 6:off - Reboot and enjoy!

if so, then stop it:$ sudo chmod +x /etc/init.d/oracle

$ sudo /etc/init.d/oracle stop
