When disaster recovery is switched , Need to put PR Terminal crontab To DR Terminal crontab;

take DR Terminal crontab To PR Terminal crontab;

Return to the original after failback crontab

Be careful ：

（1） When dr Of mrp The process didn't start , But the database plays （tnsname through ）,pr The archiving of will be done by pr Of lns Normal transmission to dr, here dr The archive deletion script of cannot delete an archive that is not applied , An error is as follows ：

RMAN-08137: warning: archived log not deleted, needed for standby or upstream capture process

therefore dr The archive directory of is easy to fill , once dr The archive directory of is full , It will lead to pr Unable to continue transferring archives , Which leads to pr The archive on the end cannot be deleted normally , When deleting, it will also report RMAN-08137: warning: archived log not deleted, needed for standby or upstream capture process, Finally lead to pr Archive full , Cause trouble ;

（2） If dr Monitoring exception of ,pr Cannot transfer archive to dr,pr Cannot backup and delete normally
