写了个小脚本，用在DG备端开机自启动: ~~~ #!/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' ~~~ 写到一个sh文件中，给x权限，然后把脚本放到rc.local里，就可以了！！
