Step 1: The below command just gives the report of backups that are used to do the restore and recover :
RMAN> run
{
set until time "to_date('2016-24-10:9:00:00','yyyy-dd-mm:hh24:mi:ss')";
restore database preview;
}
Step 2: Check the backup pieces
The below command will read the backup pieces/Copies which has datafiles and if finds any error it will report at the RMAN prompt.
run
{
allocate channel c1 type disk;
set until time "to_date('2016-02-10:9:00:00','yyyy-dd-mm:hh24:mi:ss')";
restore database validate;
}
