Oracle Service Start & Stop script and auto start

After Oracle10gR2 is installed in CentOS6.3 and you reactivate it, you will find that Oracle is not started on your own. this is normal because Oracle installation in Linux does not start on your own, you must set relevant parameters. First, we will introduce how to start oracle. 1. start Oracle in Linux and log on to CentOS. switch to oracle User permissions # su? Oracle

After installing Oracle 10g R2 in CentOS 6.3 and restarting it, you will find that Oracle is not started on your own. this is normal because Oracle installation in Linux does not start on your own, you must set relevant parameters. First, we will introduce how to start oracle.

1. start Oracle in Linux

Log on to CentOS and switch to oracle User permissions.

# Su? Oracle

Enter:

$ Sqlplus "/as sysdba"

The original image will become
SQL>

Enter
SQL> startup

You can start the database normally.

In addition, the command to stop the database is as follows:
SQL> shutdown immediate

2. check whether the Oracle DB listener is normal

Return to terminal mode and enter:

$ Lsnrctl status

Check to see if the listener is started

If it is not started, enter:

$ Lsnrctl start

Start listener

SQL> conn sys @ orcl as sysdba

Then enter the password and sys will log on to the database as sysdba.

III. start emctl

In addition, we can also find that http://localhost.localdomain: 1158/em is currently no response, here to start another, the startup command is as follows:

$ Emctl start dbconsole

The command runs for a long time. the execution result is as follows:

After you manually start the Oracle database, create a script for the system to start Oracle.

4. Oracle startup and stop scripts

1. modify the Oracle system configuration file:/etc/oratab. Only in this way can dbstart and dbshut of Oracle be used.

# Vi/etc/oratab
Orcl:/opt/oracle/102: Y

# Entries are of the form:
# $ ORACLE_SID: $ ORACLE_HOME: :

2. create the file oracle under/etc/init. d/. the content is as follows:

#!/bin/sh # chkconfig: 35 80 10 # description: Oracle auto start-stop script.## Set ORA_HOME to be equivalent to the $ORACLE_HOME# from which you wish to execute dbstart and dbshut;## Set ORA_OWNER to the user id of the owner of the# Oracle database in ORA_HOME.ORA_HOME=/opt/oracle/102 ORA_OWNER=oracle if [ ! -f $ORA_HOME/bin/dbstart ] then echo "Oracle startup: cannot start" exit fi case "$1" in 'start')# Start the Oracle databases: echo "Starting Oracle Databases ... " echo "-------------------------------------------------" >> /var/log/oracle date +" %T %a %D : Starting Oracle Databases as part of system up." >> /var/log/oracle echo "-------------------------------------------------" >> /var/log/oracle su - $ORA_OWNER -c "$ORA_HOME/bin/dbstart" >>/var/log/oracle echo "Done" # Start the Listener: echo "Starting Oracle Listeners ... " echo "-------------------------------------------------" >> /var/log/oracle date +" %T %a %D : Starting Oracle Listeners as part of system up." >> /var/log/oracle echo "-------------------------------------------------" >> /var/log/oracle su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl start" >>/var/log/oracle echo "Done." echo "-------------------------------------------------" >> /var/log/oracle date +" %T %a %D : Finished." >> /var/log/oracle echo "-------------------------------------------------" >> /var/log/oracle touch /var/lock/subsys/oracle;; 'stop')# Stop the Oracle Listener: echo "Stoping Oracle Listeners ... " echo "-------------------------------------------------" >> /var/log/oracle date +" %T %a %D : Stoping Oracle Listener as part of system down." >> /var/log/oracle echo "-------------------------------------------------" >> /var/log/oracle su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl stop" >>/var/log/oracle echo "Done." rm -f /var/lock/subsys/oracle# Stop the Oracle Database: echo "Stoping Oracle Databases ... " echo "-------------------------------------------------" >> /var/log/oracle date +" %T %a %D : Stoping Oracle Databases as part of system down." >> /var/log/oracle echo "-------------------------------------------------" >> /var/log/oracle su - $ORA_OWNER -c "$ORA_HOME/bin/dbshut" >>/var/log/oracle echo "Done." echo "" echo "-------------------------------------------------" >> /var/log/oracle date +" %T %a %D : Finished." >> /var/log/oracle echo "-------------------------------------------------" >> /var/log/oracle;; 'restart')$0 stop$0 start;; esac

3. change file permissions
# Chmod 755/etc/init. d/oracle

4. add a service
# Chkconfig -- level 35 oracle on

5. You need to stop the database before shutting down or restarting the machine.
# Ln-s/etc/init. d/oracle/etc/rc0.d/K01oracle // shutdown
# Ln-s/etc/init. d/oracle/etc/rc6.d/K01oracle // restart

6. usage
# Service oracle start // start oracle
# Service oracle stop // close oracle
# Service oracle restart // restart oracle

7. test

A. Auto Start
