三、小结

1.ALTER DATABASE ... CREATE DATAFILE
--官方说明
Creates a new empty data file in place of an old one--useful to re-create a data file that was lost with no backup.

2.StandbyFileManagement 需要参数设置为auto
DGMGRL> edit database orcl set property StandbyFileManagement=auto;
Property "standbyfilemanagement" updated
DGMGRL> edit database orcldg set property StandbyFileManagement=auto;
Property "standbyfilemanagement" updated
