RHEL5开启和关闭Oracle数据库实例,分为两步:第一步,启动监听;第二步,启动数据库实例。

一、如何启动数据库实例

1.进入到sqlplus启动实例
[oracle@RedHat ~]$ su - oracle                                 --“切换到oracle用户”
Password:
[oracle@redhat ~]$ lsnrctl start                               --“打开监听”
[oracle@redhat ~]$ sqlplus /nolog                                --“进入到sqlplus”
SQL*Plus: Release 10.2.0.1.0 - Production on Wed Oct 14 19:06:45 2009
Copyright (c) 1982, 2005, Oracle. All rights reserved.
SQL> conn /as sysdba                                              --“连接到sysdba”
Connected to an idle instance.
SQL> startup                                                     --“启动数据库实例
SQL> shutdown immediate                                         --“关闭数据库实例”

[oracle@redhat ~]$ lsnrctl stop                                 --“关闭监听”

2.用dbstart和dbshut启动和关闭数据库实例
先启动监听 lsnrctl start
启动实例   dbstart
使用dbstart命令启动数据库比较方便,但是在linux上安装好oracle之后,第一次使用dbstart命令可能会报如下错误:
Failed to auto-start Oracle Net Listene using /ade/vikrkuma_new/oracle/bin/tnslsnr
看起来貌似是监听没有起来,可是实际上,监听可以成功启动。
我们来看一下dbstart脚本,该脚本放在$ORACLE_HOME/bin下面。
搜索dbstart里面的tnslsnr:
grep tnslsnr dbstart
返回结果:
if [ -f $ORACLE_HOME_LISTNER/bin/tnslsnr ] ; then
    echo "Failed to auto-start Oracle Net Listene using $ORACLE_HOME_LISTNER/bin/tnslsnr"

返回结果中发现有$ORACLE_HOME_LISTNER变量,有可能是该变量的路径不对,我们继续搜索ORACLE_HOME_LISTNER
grep ORACLE_HOME_LISTNER dbstart

返回结果:

# 3) Set ORACLE_HOME_LISTNER
ORACLE_HOME_LISTNER=/ade/vikrkuma_new/oracle
if [ ! $ORACLE_HOME_LISTNER ] ; then
echo "ORACLE_HOME_LISTNER is not SET, unable to auto-start Oracle Net Listener"
LOG=$ORACLE_HOME_LISTNER/listener.log
if [ -f $ORACLE_HOME_LISTNER/bin/tnslsnr ] ; then
    $ORACLE_HOME_LISTNER/bin/lsnrctl start >> $LOG 2>&1 &
    export VER10LIST=`$ORACLE_HOME_LISTNER/bin/lsnrctl version | grep "LSNRCTL for " | cut -d' ' -f5 | cut -d'.' -f1`
    echo "Failed to auto-start Oracle Net Listene using $ORACLE_HOME_LISTNER/bin/tnslsnr"
        $LOGMSG "Restart Oracle Net Listener using an alternate ORACLE_HOME_LISTNER: lsnrctl start"

我们发现ORACLE_HOME_LISTNER=/ade/vikrkuma_new/oracle中,指定的路径不对,,需要对这一行重新编辑,使其路径制定到$ORACLE_HOME

用vi编辑dbstart,将ORACLE_HOME_LISTNER=/ade/vikrkuma_new/oracle更改为
export ORACLE_HOME_LISTNER=$ORACLE_HOME
然后保存退出,此时再运行dbstart,已经不报错了,但是没有任何反应,ps一下进程,没有oracle的进程,说明oracle实例没有正常启动。
此时的原因是在/etc/oratab的设置问题,我们cat一下,发现
zgz:/home/oracle/product/10g:N
最后设置的是"N"(我的环境中只有一个实例,因此只有一行配置语句),我们需要把“N”修改为“Y”。
以上的工作做好之后,dbstart就可以正常使用了:
[oracle@redhat bin]$ lsnrctl start                                  --“启动监听”
[oracle@redhat bin]$ dbstart                                   --“启动数据库实例”
[oracle@redhat bin]$ dbshut                                    --“关闭数据库实例”
[oracle@redhat bin]$ lsnrctl stop                              --“关闭监听”

二、如何使数据库实例和linux系统一起启动
在/etc/rc.d/rc.local中加入如下语句即可实现同系统启动实例:
su - oracle -c "lsnrctl start"
