Hi all,

I have a doubt regarding recovering database.


I have a rman backup in disk and archive logs in separate disk.
when a datafile is missing or some problem with database, at that time from where the data is used to recover the ? either from backup disk or from archive logs disk?

PLease clear my doubt.


Mohan

It could depend on what you are recovering from.

Check Backup and Recovery Basics for more information regarding restore & recovery.

if u have datafile missing then copy back the specific datafile from the backup location to the original location
then if u startup put
RECOVER DATABASE command,
then it will ask for archive logs to apply something like this
ORA-00279: change 655683 generated at 05/21/2009 11:26:58 needed for thread 1
ORA-00289: suggestion :
D:\ORACLE\PRODUCT\10.2.0\FLASH_RECOVERY_AREA\ARC00010_0686254531.001
ORA-00280: change 655683 for thread 1 is in sequence #10

here ARC00010_0686254531.001 is the archive file it is asking paste the path including filename after this and press ENTER
now sme times it will b enough otherwise it will ask for next archive file after everything is finished
it will say
Log applied.
Media recovery complete.
now issue
SQL> alter database open;
Database altered.

the database is open u can shutdown and startup again to check if it is working.Always do this to verify

This is too generic of a response. How will this help the OP with "some problem with database" ?

In addition, the OP is talking about restore & recovery with RMAN.
