转：oracle随系统启动的脚本

原贴地址： http://space.itpub.net/26162300/viewspace-704722

添加oracle随系统启动的脚本
启动脚本已随安装的软件安装到系统 不需要自己编写

脚本位置:

  $ORACLE_HOME/bin/dbstart
  $ORACLE_HOME/bin/dbshut

启动脚本中有一个路径变量值设置错误 要手动修正

 [oracle@dba ~]$ sed -n '78p' $ORACLE_HOME/bin/dbstart
 ORACLE_HOME_LISTNER=/ade/vikrkuma_new/oracle
 [oracle@dba ~]$ sed -i 's!/ade/vikrkuma_new/oracle!$ORACLE_HOME!' $ORACLE_HOME/bin/dbstart
 [oracle@dba ~]$ sed -n '78p' $ORACLE_HOME/bin/dbstart
 ORACLE_HOME_LISTNER=$ORACLE_HOME
 [oracle@dba ~]$

要想使dbstart命令生效 还需要修改/etc/oratab里的内容

 [oracle@dba ~]$ grep $ORACLE_SID /etc/oratab
 ora10g:/u01/oracle/product/10.2.0:N
 [oracle@dba ~]$

改成

 ora10g:/u01/oracle/product/10.2.0:Y

之后就可以使用dbstart和dbshut来启停数据库了

 [oracle@dba ~]$ ps -ef | grep ora_ | grep -v grep
 [oracle@dba ~]$ dbstart
 Processing Database instance "ora10g": log file /u01/oracle/product/10.2.0/startup.log
 [oracle@dba ~]$ ps -ef | grep ora_ | grep -v grep

 oracle   12394     1 12 07:24 ?        00:00:00 ora_j000_ora10g
 [oracle@dba ~]$ dbshut
 [oracle@dba ~]$ ps -ef | grep ora_ | grep -v grep
 [oracle@dba ~]$

借助这两个命令结合shell_script写个自己的脚本

[oracle@dba ~]$ cat /etc/rc.d/init.d/dbora
#!/bin/bash
# chkconfig: 35 85 90
# description: Oracle auto start-stop script.
# AUTH:seker

start(){
 if ps aux | grep ora_ | grep -v grep &>/dev/null
 then
  echo -n $"cannot start database: database is already running."
  failure $"cannot start database: database is already running."
  echo
  exit 1
 else
  echo -n $"Starting Database: "
  daemon su - $ORA_OWNER -c "dbstart" && touch /var/lock/subsys/`basename $0`
  echo
 fi
 
}
stop(){
 if ps aux | grep ora_ | grep -v grep &>/dev/null
 then
  echo -n $"Stoping Database: "
  daemon su - $ORA_OWNER -c "dbshut" && rm -f /var/lock/subsys/`basename $0`
  echo
 else
  echo -n $"cannot stop database:Database is not already running."
  failure $"cannot stop database:Database is not already running."
  echo
  exit 1
 fi
}

[oracle@dba ~]$

添加到启动脚本目录

 [root@dba ~]# chmod +x /etc/rc.d/init.d/dbora
 [root@dba ~]# chkconfig --add dbora

也可以使用service调用

 [root@dba ~]# service dbora stop
 [root@dba ~]# service dbora start
