RedHat（Linux） Oracle数据库设置开机自启动

1 首先修改/etc/oratab文件添加如下行：
ycr:/u01/app/oracle/product/12.1.0/dbhome_1:Y

关于/etc/oratab文件解释如下：
# This file is used by ORACLE utilities. It is created by root.sh
# and updated by either Database Configuration Assistant while creating
# a database or ASM Configuration Assistant while creating ASM instance.

# 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 field 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.
#
#
ycr:/u01/app/oracle/product/12.1.0/dbhome_1:Y
上面三个参数的意义分别为，实例名、ORACLE HOME、是否允许使用dbstart启动数据库

2 修改文件/etc/rc.d/rc.local，添加如下行：
su oracle -lc "/u01/app/oracle/product/12.1.0/dbhome_1/bin/lsnrctl start"
su oracle -lc "/u01/app/oracle/product/12.1.0/dbhome_1/bin/dbstart"

关于rc.local解释如下：
#!/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
su oracle -lc "/u01/app/oracle/product/12.1.0/dbhome_1/bin/lsnrctl start"
su oracle -lc "/u01/app/oracle/product/12.1.0/dbhome_1/bin/dbstart"

/etc/rc.d/rc.local做为初始化脚本中,的最后一个随开机启动。
