自动启动和关闭Oracle 脚本

   配置完ASM实例后，每次启动oracle数据库服务器的时候要先启动ASM实例，然后启动数据库实例；关闭的时候，需要先关闭oracle数据库实例，然后关闭ASM实例；敲起命来来麻烦的很，因而改进了原来的shell脚本来更好的实现自动化，为了加快启动和关闭的速度，该脚本不包含dbconsole的启动和关闭，脚本同样适用于非ASM环境。

一：总脚本调用/usr/bin/startdb和/usr/bin/stopdb脚本，使用chkconfig命令创建相关的符号链接后就可以使用service命令调用

[root@ora10g ~]# cat /etc/init.d/oracle
#!/bin/sh
#chkconfig: 35 85 15
#description:oracle
#function: start .. stop the oracle and asm instance on 10g R2 64bit
#author:lw.yang
#version: V.2.0

# Source function library.
. /etc/rc.d/init.d/functions

case "$1" in
           start)
           /usr/bin/startdb
            ;;

        stop)
            /usr/bin/stopdb
            ;;

        *)
            echo $"Usage: $0 {start|stop}"
            exit 1

esac

二：/usr/bin/startdb脚本用来启动ASM实例和ORACLE数据库实例和监听器，启动前会进行判断是否配置了ASM以及实例是否已经启动，ASM实例需要ocssd.bin后台进程启动才可以运行

[root@ora10g ~]# cat /usr/bin/startdb
#!/bin/sh

#define variables

ASM_PID=$(pidof ocssd.bin)
ASM_PROC=$(ps -ef |grep asm_ |grep -v 'grep' |wc -l)

D_SID=$(su - oracle -c "env |grep ORACLE_SID|cut -d "=" -f 2")
DB_PROC=$(ps -ef |grep ora_ |grep -E 'smon|pmon|ckpt|lgwr' |wc -l)

#startup asm instance

if [ -z $ASM_PID ];then
   echo "Not configure use ASM"
   continue
   elif [ $ASM_PROC -gt "7" ];then
   echo "ASM instance already running"
   else
   su - oracle  -c "export ORACLE_SID=+ASM && sqlplus /nolog<<EOF
   conn /as sysdba
   startup
   exit
   EOF"
fi

#startup database instance

    if [ $DB_PROC -eq "4" ];then
        echo "Database instance already running,shutdown it firtst"
        else
        su - oracle -c "lsnrctl start"
        su - oracle -c "export ORACLE_SID=$D_SID && sqlplus /nolog<<EOF
        conn /as sysdba
        startup
        exit
        EOF"
        touch /var/lock/subsys/oracle
    fi

三：/usr/bin/stopdb脚本用来关闭监听器，oracle数据库实例和ASM实例，关闭之前会先进行判断是否使用ASM以及相关实例是否已经关闭
 

#!/bin/sh

#define variables

ASM_PID=$(pidof ocssd.bin)
ASM_PROC=$(ps -ef |grep asm_ |grep -v 'grep' |wc -l)

D_SID=$(su - oracle -c "env |grep ORACLE_SID|cut -d "=" -f 2")
DB_PROC=$(ps -ef |grep ora_ |grep -E 'smon|pmon|ckpt|lgwr' |wc -l)

#stop database instance

    if [ $DB_PROC -eq "0" ];then
        echo "Database instance already shutdown"
        else
    su - oracle -c "lsnrctl stop"
    su - oracle -c "export ORACLE_SID=$D_SID && sqlplus /nolog<<EOF
    conn /as sysdba
    shutdown immediate
    exit
    EOF"
        rm -f /var/lock/subsys/oracle
    fi

#stop asm instance

if [ -z $ASM_PID ];then
   echo "Not configure use ASM"
   elif [ $ASM_PROC -eq "0" ];then
   echo "ASM instance already shutdown"
   exit
   else
   su - oracle  -c "export ORACLE_SID=+ASM && sqlplus /nolog<<EOF
   conn /as sysdba
   shutdown immediate
   exit
   EOF"
fi

四:测试

非ASM环境下，数据库实例已经启动下测试：
[root@ora10g ~]# service oracle start
Not configure use ASM
Database instance already running,shutdown it firtst


[root@ora10g ~]# service oracle stop

五：设置操作系统环境变量

设置NLS_DATE_FORMAT和NLS_LANG环境变量，这两个变量需要同时设定，否则执行select sysdate from dual的时候，输出格式DD-MON-YY

SQL> select sysdate from dual;

SYSDATE
---------
02-JUN-11

[oracle@ora10g ~]$ env |grep NLS
NLS_LANG=american_america.UTF8
NLS_DATE_FORMAT=YYYY-MM-DD HH24:MI:SS

SQL> select sysdate from dual;

SYSDATE
-------------------
2011-06-02 10:04:49

设置默认编辑器为vim，若不设置该变量，在sqlplus中将无法使用ed命令

SQL> ed
Wrote file afiedt.buf
27

[oracle@ora10g ~]$ env |grep EDITOR
EDITOR=vim
