Important FAQ's on RMAN asked by Interviewers.
I have few questions on RMAN. Please guide.
1.1 IF I DO RESTORE second time, WILL IT SKIP already backed up datafile and archivelog file FILE AND skip RESTORE them AGAIN?
1.2 Is that because of backup optimization on?
2 ) CAN I SCHEDULE FULL BACKUP like basically same cron same time FROM BOTH THE NODES.? Does it start backing up twice or its one process logically. How does this work, if possible.
3) What is the difference between active clone and dbrefresh?
4) In order to find SCN for PITR. How can I find what was SCN earlier when human error happened?
Thanks In advance!!
