RedHat（Linux） Oracle資料庫設定開機自啟動

標籤：ted   oracle資料庫   while   red   /etc/   entry   ora   multiple   directory   

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




關於/etc/oratab檔案解釋如下：
# 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
上面三個參數的意義分別為，執行個體名、ORACLE HOME、是否允許使用dbstart啟動資料庫


2 修改檔案/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"


關於rc.local解釋如下：
#!/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做為初始化指令碼中,的最後一個隨開機啟動。
