linux系统启动时自动启用oracle standby备库日志

1.创建shell文件， 内容参考如下

  [oracle@localhost ~]$ cat /home/oracle/dgstart.sh

#!/bin/sh

export ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1

export ORACLE_SID=实例名

export PATH=$PATH:$ORACLE_HOME/bin

sqlplus / as sysdba @/home/oracle/standby_log_apply.sql

[oracle@localhost ~]$ cat /home/oracle/standby_log_apply.sql

startup;

alter database recover managed standby database using current logfile disconnect;

2. 使用root用户将oracle下的启动脚本加入/etc/rc.local

  [root@localhost ~]$ cat /etc/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

su - oracle -lc "/u01/app/oracle/product/11.2.0/db_1/bin/lsnrctl start"

su - oracle -lc "/home/oracle/dgstart.sh"
