oracle数据库开机自启

登录系统后，切换到oracle用户，查看oracle_home是否设置

1 2	[oracle@localhost ~]$ echo $ORACLE_HOME /u01/app/oracle

如果查询的结果是空的话，需要编辑/home/oracle/.bash_profile

[oracle@localhost ~]$ vim /home/oracle/.bash_profile

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

# User specific environment and startup programs
ORACLE_BASE=/u01/app
ORACLE_HOME=$ORACLE_BASE/oracle
ORACLE_SID=hfdpc; export ORACLE_SID
PATH=$ORACLE_HOME/bin:$PATH:$HOME/bin

LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib
export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH LD_LIBRARY_PATH LANG

oracle_home的路径可以在 /etc/oratab下面看

修改好oracle_home的设置后，需要使脚本生效，

1	[oracle@localhost ~]$ source /home/oracle/.bash_profile

2.修改/etc/oratab 的配置，需要切换到root用户

1 2	[iyunv@localhost ~]$ cat /etc/oratab hfdpc:/u01/app/oracle:N

把上面的"N"修改成"Y"

1 2	[iyunv@localhost ~]$ cat /etc/oratab hfdpc:/u01/app/oracle:Y

3.编辑启动脚本/etc/rc.d/rc.local，添加数据库启动脚本dbstart和监听启动脚本，需要切换到root用户进行操作

[iyunv@localhost ~]$ cat /etc/rc.d/rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local

在脚本里面加上oracle自带的启动脚本dbstart和监听启动脚本，编辑好后保存

touch /var/lock/subsys/local
su oracle -lc "/u01/app/oracle/bin/lsnrctl start"
su oracle -lc /u01/app/oracle/bin/dbstart

4.切换到oracle用户，在$ORACLE_HOME/bin路径下，执行dbstart

[iyunv@localhost ~]# su - oracle
[oracle@localhost ~]$ cd /u01/app/oracle/bin/
[oracle@localhost bin]$ dbstart

*在$ORACLE_HOME/bin下执行dbstart，报错“Failed to auto-start Oracle Net Listene using /ade/vikrkuma_new/oracle/bin/tnslsnr“。原因是dbstart调用的tnslsnr脚本位置有错。
解决的方法是：编辑$ORACLE_HOME/bin/dbstart,
查找“ORACLE_HOME_LISTENER”变量的定义处，
修改“ORACLE_HOME_LISTENER＝/ade/vikrkuma_new/oracle”为“ORACLE_HOME_LISTENER＝$ORACLE_HOME”
