创建控制文件快照

如果备库控制文件损坏，adg需要继续保持同步，那么如何修复
应该从主库拿最新的控制文件，然后配置一下

sqlplus / as sysdba
alter database create standby controlfile as '/tmp/prod_for_standby.ctl';

rman target /
backup format='/tmp/prod_standby.ctl' current controlfile for standby;


backup format='/tmp/prod_standby.ctl' as copy current controlfile for standby;


run {
allocate channel d1 device type disk format '/backup/%U';
allocate channel d2 device type disk format '/backup/%U';
sql 'alter system archive log current'
backup database include current controlfile for standby;
sql 'alter system archive log current';
backup archivelog all;
}
