Linux配置Oracle 11g自动启动
Linux配置Oracle 11g自动启动
安装完毕Oracle 11g每次都得手动启动 | 停止数据库（dbstart | dbshut）、监听器（lsnrctl）、控制台（emtcl）。
设置一下，若手动启动数据库的同时监听器没有启动（即启动数据库时自动启动监听器，停止数据库时停止监听器），则需要修改dbstart脚本文件：
|
1
2
|
[oracle@localhost ~]$ cd /u01/app/oracle/product/11.1.0/db_1/bin/
[oracle@localhost ~]$ vi dbstart
|
找到下面的代码段：

# First argument is used to bring up Oracle Net Listener
ORACLE_HOME_LISTNER=$1
### 需要将此处的 ORACLE_HOME_LISTNER=$1 修改为 ORACLE_HOME_LISTNER=$ORACLE_HOME
if [ ! $ORACLE_HOME_LISTNER ] ; then
echo "ORACLE_HOME_LISTNER is not SET, unable to auto-start Oracle Net Listener"
echo "Usage: $0 ORACLE_HOME"
else
LOG=$ORACLE_HOME_LISTNER/listener.log
|
同样，修改dbshut：

[oracle@localhost ~]$ vi dbshut
# The this to bring down Oracle Net Listener
ORACLE_HOME_LISTNER=$1
### 需要将此处的 ORACLE_HOME_LISTNER=$1 修改为 ORACLE_HOME_LISTNER=$ORACLE_HOME
if [ ! $ORACLE_HOME_LISTNER ] ; then
echo "ORACLE_HOME_LISTNER is not SET, unable to auto-stop Oracle Net Listener"
echo "Usage: $0 ORACLE_HOME"
else
LOG=$ORACLE_HOME_LISTNER/listener.log
|
完成后配置Linux启动脚本oracle，内容如下：
|

2
|
[oracle@localhost bin]$ cd /etc/init.d/
[oracle@localhost init.d]$ vi oracle

$0 stop
$0 start
;;

echo $"Usage: `basename $0` {start|stop|reload|reload}"
exit 1
esac
exit 0
|
赋予脚本可执行权限：
|
1
|
[oracle@localhost init.d]$ chmod 750 /etc/init.d/oracle
|
建立链接：
|
1
2
|
[oracle@localhost init.d]$ ln -s /etc/init.d/oracle /etc/rc1.d/K61oracle
[oracle@localhost init.d]$ ln -s /etc/init.d/oracle /etc/rc3.d/S61oracle
|
启用脚本并添加到服务：
|
1
2
|
[oracle@localhost init.d]$ chkconfig --level 345 oracle on
[oracle@localhost init.d]$ chkconfig --add oracle
|
注意：
这样的脚本一般不会启动实例，如果想让实例也随脚本一起启动的话，就需要修改文件/etc/oratab
如果这个文件不存在，就要运行脚本文件产生它。

# This file is used by ORACLE utilities. It is created by root.sh
# and updated by the Database Configuration Assistant when creating
# a database.
# A colon, ':', is used as the field terminator. A new line terminates
# the entry. Lines beginning with a pound sign, '#', are comments.
#
# Entries are of the form:
# $ORACLE_SID:$ORACLE_HOME:<
N
|Y>:
#
# The first and second fields are the system identifier and home
# directory of the database respectively. The third filed indicates
# to the dbstart utility that the database should , "Y", or should not,
# "N", be brought up at system boot time.
#
# Multiple entries with the same $ORACLE_SID are not allowed.

orcl:/u01/app/oracle/product/11.1.0/db_1:Y
|
可以看出，实例orcl是自动启动的（标识为Y），只要在这里配置好，再配合上面的脚本，即可实现自动启动。
