The STATUS is 0 when the recovery is sufficient and it is safe to OPEN the database.
The fhsta can have one of the below values:
0 – DB is consistent. No more recovery required.
1 – DB needs more recovery. It’s time to apply more archives.
4 – DB is in a FUZZY state. Was the backup good?

In this case the next_change# SCN in thread 1 sequence 25 is lower than sequence 13 thread 2. In a RAC environment, we use the lower to ensure we have the redo required from BOTH threads. In other words, we use the lower (thread# 1) to ensure that ALL scn (s) in thread #1 exist in the available sequence for thread #2.
So we will set sequence 26 for thread 1 for RMAN 'until sequence' recovery, because RMAN stops the recovery before applying the indicated sequence. Log sequence for recovery needs always be sequence+1 to end at +1 after applying the prior sequence. I.e.:
SET UNTIL SEQUENCE 26 THREAD 1;
