1.设置/etc/oratabtestdb2:/opt/oracle/product/9.2.0:Y要把最后一个选项从N改为Y 2.测试dbstart和dbshut命令dbstart 和dbshut会检查/etc/oratab的设置,如果设置为Y,则执行启动或关闭,如果设置成N,则不做任何操作测试方法:su - oracle dbstart or dbshut 我在测试过程中,报错,意思是找不到init文件,进入sqlplus创建一个init文件即可:
sqlplus /nolog
conn /as sysdba
create pfile from spfile; 再次测试则成功 3.创建操作系统启动和关闭时调用的文件
3.1)修改/etc/rc.d/init.d/oracle文件
su - root
要 在开机关机时自动启动和关闭数据库的话,需要修改 Linux 的启动脚本文件,这里要创建/etc/rc.d/init.d/oracle文件,这个文件的脚本会调用 dbshut 及 dbstart,内容如下: # !/bin/sh## /etc/rc.d/init.d/oracle# 解说∶启动及停止 Oracle 数据库和监听程序# 检查如何执行脚本文件case "$1" in start) echo -n "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 -n "Starting Oracle Listeners: " su - oracle -c "lsnrctl 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 -n "Shutting Down Oracle Listeners: " echo "----------------------------------------------------" >> /var/log/oracle date +"! %T %a %D : Shutting Down Oracle Databases as part of system down." >> /var/log/oracle echo "----------------------------------------------------" >> /var/log/oracle su - oracle -c "lsnrctl stop" >> /var/log/oracle echo "Done." rm -f /var/lock/subsys/oracle echo -n "Shutting Down Oracle Databases: " 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 ;; restart) echo -n "Restarting Oracle Databases: " echo "----------------------------------------------------" >> /var/log/oracle date +"! %T %a %D : Restarting Oracle Databases as part of system up." >> /var/log/oracle echo "----------------------------------------------------" >> /var/log/oracle su - oracle -c dbshut >> /var/log/oracle su - oracle -c dbstart >> /var/log/oracle echo "Done." echo -n "Restarting Oracle Listeners: " su - oracle -c "lsnrctl stop" >> /var/log/oracle su - oracle -c "lsnrctl 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 ;; *) echo "Usage: oracle {start|stop|restart}" exit 1esac编辑完这个文件后,要将其改为可执行chmod +x oraclechmod 777 oracle然后测试一下,保证该脚本可以正常执行cd /etc/rc.d/init.d./oracle start./oracle stop./oracle restart 3.2)在相应的runlevel目录里建立符号连接
要在正确的执行等级目录 (runlevel ctories) /etc/rc.d/rcX.d
中建立及删除符号连结 (symbolic links)。
以下指令确保在执行等级 2, 3 及 5 下会启动数据库,级别4没有使用,所以不管。∶
ln -s /etc/rc.d/init.d/oracle /etc/rc.d/rc2.d/S99oracle
ln -s /etc/rc.d/init.d/oracle /etc/rc.d/rc3.d/S99oracle
ln -s /etc/rc.d/init.d/oracle
/etc/rc.d/rc5.d/S99oracle要在重新启动时停止数据库,我们需要以下连结∶ ln -s
/etc/rc.d/init.d/oracle /etc/rc.d/rc0.d/K01oracle
ln -s /etc/rc.d/init.d/oracle /etc/rc.d/rc6.d/K01oracle3.2)修改dbshut文件
因为dbshut命令默认是用shutdown
normal方式关闭数据库,但实际情况下这种方式很难关掉数据库,因此需要更改dbshut脚本,将其中的shutdown命令改为 shutdown
immediate su - oraclecd $ORACLE_HOME/binvi dbshut
