寫了個小腳本，用在DG備端開機自啟動:
~~~
#!/bin/sh
#db auto be mount status when os restart
#20151224
su - oracle -c 'sqlplus / as sysdba'<<EOF
startup nomount;
alter database mount standby database;
alter database recover managed standby database using current logfile disconnect from session;
EOF
su - oracle -c 'lsnrctl start'
~~~
寫到一個sh文件中，給x權限，然后把腳本放到rc.local里，就可以了！！
