Linux下Oracle 10g自动启动与关闭的实现

 

环境：RHEL 5.5 + Oracle 10g + VMWare 5.5

 

尝试在linux下进行oracle的自动启动与关闭，经过多次摸索，完整实现如下：

1、修改oratab文件，使数据库自动启动

#vi /etc/oratab

sid:/opt/app/ora10g/oracle/product/10.2.0/db_1:Y   -----即把原来的N修改为Y。

 

2、修改dbstart、dbshut脚本，使之能够自动启动、关闭LISTENER

将dbstart与dbshut两个脚本中的ORACLE_HOME_LISTNER=$1改为

ORACLE_HOME_LISTNER=$ORACLE_HOME即可（我这个版本好像只修改dbstart,dbshut中没有什么要修改）

 

3、编写启动脚本/etc/rc.d/init.d/oracle

#!/bin/bash # #################FUNCTION############# # # AutoStart Oracle and listener # AutoStop Oracle and listener # ##################################### # # Created by ZhouYS 2003-11-26 # Modified by XiaoFengBin 2010-09-13 # # chkconfig: 2345 99 01 # description: oracledb starts/stops the Oracle server case "$1" in start) 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 - oracle -c "dbstart" >> /var/log/oracle echo "Done." 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 - oracle -c "lsnrctl start" >> /var/log/oracle echo "Done." echo "Starting EM ... " echo "-------------------------------------------------" >> /var/log/oracle date +" %T %a %D : Starting EM as part of system up." >> /var/log/oracle echo "-------------------------------------------------" >> /var/log/oracle su - oracle -c "emctl start dbconsole" >> /var/log/oracle echo "Done." echo "Starting isqlplus ... " echo "-------------------------------------------------" >> /var/log/oracle date +" %T %a %D : Starting isqlplus as part of system up." >> /var/log/oracle echo "-------------------------------------------------" >> /var/log/oracle su - oracle -c "isqlplusctl start" >> /var/log/oracle echo "Done." echo "" echo "-------------------------------------------------" >> /var/log/oracle date +" %T %a %D : Finished." >> /var/log/oracle echo "-------------------------------------------------" >> /var/log/oracle touch /var/lock/subsys/oracle ;; stop) echo "Stoping EM ... " echo "-------------------------------------------------" >> /var/log/oracle date +" %T %a %D : Stoping EM as part of system down." >> /var/log/oracle echo "-------------------------------------------------" >> /var/log/oracle su - oracle -c "emctl stop dbconsole" >>/var/log/oracle echo "Done." echo "Stoping isqlplus ... " echo "-------------------------------------------------" >> /var/log/oracle date +" %T %a %D : Stoping isqlplus as part of system down." >> /var/log/oracle echo "-------------------------------------------------" >> /var/log/oracle su - oracle -c "isqlplusctl stop" >>/var/log/oracle echo "Done." 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 - oracle -c "lsnrctl stop" >> /var/log/oracle echo "Done." 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 - oracle -c "dbshut" >>/var/log/oracle echo "Done." echo "" echo "-------------------------------------------------" >> /var/log/oracle date +" %T %a %D : Finished." >> /var/log/oracle echo "-------------------------------------------------" >> /var/log/oracle rm -f /var/lock/subsys/oracle ;; restart) $0 stop $0 start ;; *) echo "Usage: oracle {start|stop|restart}" exit 1 esac exit 0

 

4、添加服务
[root@by init.d]# chmod 755 oracle
[root@by init.d]# chmod +x /etc/rc.d/init.d/oracle
[root@by init.d]# chkconfig --add oracle
[root@by init.d]# chkconfig --list oracle
oracle          0:关闭  1:关闭  2:启用  3:启用  4:启用  5:启用  6:关闭

 

如果出现：bash: chkconfig: command not found，那么一般是chkconfig包没装或者装了路径没设置对。

[root@by init.d]# PATH="$PATH":/sbin
[root@by init.d]# echo $PATH
/sbin:/usr/kerberos/sbin:/opt/oracle/product/10.2.0/db_1/bin:/usr/sbin:/usr/lib/qt-3.3/bin:/usr/kerberos/bin:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/home/oracle/bin:/sbin

 

5、测试服务

[root@by init.d]# service oracle stop

 

如果出现如下错误：
Stoping EM ...
/home/oracle/.bash_profile: line 23: ulimit: open files: cannot modify limit: 不允许的操作
Done.

 

可在

[root@by init.d]# vi /etc/security/limits.conf
添加如下内容：
oracle              soft    nproc   2047
oracle              hard    nproc   16384
oracle              soft    nofile  1024
oracle              hard    nofile  65536

Ok，一切完成。关闭系统，重启，最后验证，都自动启动了。
