After Oracle 11g is successfully installed, use chkconfig to automatically enable settings in Linux.

Note: you must first modify the environment variables of Oracle and root users.
 
Vi ~ /. Bash_profle
 
Add the following content:
 
Umask 022
 
Export ORACLE_BASE =/home/oracle/app
 
Export ORACLE_HOME = $ ORACLE_BASE/oracle/product/11.2.0/dbhome_1
 
Export ORACLE_SID = orcl
 
Export PATH = $ PATH: $ HOME/bin: $ ORACLE_HOME/bin
 
Export LD_LIBRARY_PATH = $ ORACLE_HOME/lib:/usr/lib
 
 
 
1. Use the root user to modify the/etc/oratab file:
$ Vi/etc/oratab
Orcl:/home/oracle/app/oracle/product/11.2.0/dbhome_1: N
Changed:
Orcl:/home/oracle/app/oracle/product/11.2.0/dbhome_1: Y
 
That is, change the last N to Y.
 

2. Use the oracle user to modify the $ ORACLE_HOME/bin/dbstart file:
# Su-oracle
$ Cd $ ORACLE_HOME/bin
$ Vi dbstart
Locate ORACLE_HOME_LISTNER =... and change it
ORACLE_HOME_LISTNER = $ ORACLE_HOME
Modify dbshut as well
 
Vi dbshut
 
ORACLE_HOME_LISTNER = $ ORACLE_HOME
 

Note: It is a modification, not an addition, but the search function of vi is used for searching:
ORACLE_HOME_LISTNER, modify and save the modification.
 

Iii. Test and run dbshut. Check whether dbstart can start the oracle service and listener service:
 
Or an error may be reported during startup, indicating that dbstart or dbshut has insufficient permissions.
1. modify the permissions of dbstart and dbshut log files:
$ Su-root
# Cd $ ORACLE_HOME
# Chown oracle: oinstall $ ORACLE_HOME/startup. log
# Chown oracle: oinstall $ ORACLE_HOME/shutdown. log
# Chown oracle: oinstall $ ORACLE_HOME/listener. log
 

2. Execute the corresponding script for testing (optional)
# Su-oracle
$ Cd $ ORACLE_HOME/bin
$./Dbstart (./dbshut)
$ Ps-efw | grep ora _
$ Lsnrctl status
$ Ps-efw | grep LISTEN | grep-v grep
 

4. Create a service
$ Su-root
# Cd/etc/rc. d/init. d/
# Vi oracle
 
----- Script -----
 

#! /Bin/bash
 

# Chkconfig: 345 99 10
 

# Description: Startup Script for Oracle Databases
 

 
 

#/Etc/rc. d/init. d/oracle
 

Export ORACLE_BASE =/home/oracle/app
 

Export ORACLE_HOME = $ ORACLE_BASE/oracle/product/11.2.0/dbhome_1
 
Export ORACLE_SID = orcl
 
Export PATH = $ PATH: $ HOME/bin: $ ORACLE_HOME/bin
 
ORA_OWNR = "oracle"
 
# If the executables do not exist -- display error
 
If [! -F $ ORACLE_HOME/bin/dbstart-o! -D $ ORACLE_HOME]
 
Then
 
Echo "Oracle startup: cannot start"
 
Exit 1
 
Fi
 
# Depending on parameter -- startup, shutdown, restart
 
# Of the instance and listener or usage display
 
Case "$1" in
 
Start)
 
# Oracle listener and instance startup
 
Echo-n "Starting Oracle :"
 
Su-$ ORA_OWNR-c "$ ORACLE_HOME/bin/dbstart"
 
Su-$ ORA_OWNR-c "$ ORACLE_HOME/bin/lsnrctl start"
 
Touch/var/lock/Oracle
 
Su-$ ORA_OWNR-c "$ ORACLE_HOME/bin/emctl start dbconsole"
 
# Su-$ ORA_OWNR-c "$ ORACLE_HOME/bin/isqlplusctrl start"
 
Echo "OK"
 
;;
 
Stop)
 
# Oracle listener and instance shutdown
 
Echo-n "Shutdown Oracle :"
 
Su-$ ORA_OWNR-c "$ ORACLE_HOME/bin/emctl stop dbconsole"
 
# Su-$ ORA_OWNR-c "$ ORACLE_HOME/bin/isqlplusctrl stop"
 
Su-$ ORA_OWNR-c "$ ORACLE_HOME/bin/dbshut"
 
Su-$ ORA_OWNR-c "$ ORACLE_HOME/bin/lsnrctl stop"
 
Rm-f/var/lock/Oracle
 
Echo "OK"
 
;;
 
Reload | restart)
 
$0 stop
 
$0 start
 
;;
 
*)
 
Echo "Usage: 'basename $ 0' start | stop | restart | reload"
 
Exit 1
 
Esac
 
Exit 0
 
 
 
---- Skip the following steps if the startup is successful ----
 
5. check:

Based on the above running results, when the corresponding running level is on (for example, 5: on), in the corresponding/etc/rc. d/rcN. d (for example, the value corresponding to 5: on is/etc/rc. d/rc5.d) the following will generate a file: S99oradbstart, use vi S99oradbstart to open the file, you can see the content of the file and/etc/rc. d/init. d/oradbstart has the same content, indicating that the configuration is successful. In fact, S99oradbstart is one to/etc/rc. d/init. d/oradbstart link, we can use the file command to view:

$ File/etc/rc. d/rc5.d/S99oradbstart

S99oradbstart: symbolic link to '../init. d/oradbstart

6. One Note:
 
In the script file: # chkconfig: 345 99 10
 
It is pointed out that Level 3 and Level 5 start this service, and 99 is in the corresponding/etc/rc. d/rcN. d (N is the level specified above, here is 345) the serial number of the link file generated under the directory (startup priority level) S99oradbstart, 10. d/rcN. d (N is a level other than 345) the serial number of the link file generated by the Directory (priority of service stop) K10oradbstart.
