Filed under: RMAN — yasinsaygili @ 5:42 pm

Today DBA use backup solution ,it is very important that but sometimes this backup will be problem.This situation will be chaos for DBA ,We understand  about backup situations.DBA should check backup, so DBA need “LOGICAL CHECK“.RMAN is consist of logical check system.If system check up corraption for backup , result is in V$DATABASE_BLOCK_CORRUPTION.

I have example for this problem

run

{

SET MAXCORRUPT FOR DATAFILE 4 TO 3 ;

BACKUP CHECK LOGİCAL

DATAFILE 4;

}

P.S. : Datafile 4 ,no more than three with corruption, this is border with constant value,this is datafile 4.
