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;

PROMPT STEP 6: POST-RESETLOGS SANITY (TEMPFILES, MISSING FILES, TABLESPACES)
PROMPT ==============================================================
PROMPT -- TEMP tablespace presence check
COLUMN tablespace_name FORMAT A20

SELECT tablespace_name, status, contents

PROMPT -- Existing tempfiles
SELECT file#, SUBSTR(name,1,80) AS name, status, enabled
FROM v$tempfile

PROMPT ACTION: If no tempfiles, add per your standards:
PROMPT Example:
PROMPT ALTER TABLESPACE TEMP ADD TEMPFILE '/<path>/temp01.dbf' SIZE 10M;
PROMPT -- Detect MISSING000xx placeholders created in controlfile
SELECT file#,
status,
enabled,
SUBSTR(name,1,60) AS name
FROM v$datafile
WHERE name LIKE '%MISSING%'
ORDER BY file#;
PROMPT ACTION: If original files exist, rename placeholders:
PROMPT Example:
PROMPT ALTER DATABASE RENAME FILE 'MISSING00004' TO '/<path>/users01.dbf';
PROMPT -- Cross-check file/tablespace alignment for anomalies seen in alert.log

PROMPT COMMON ACTIONS:
PROMPT - Bring intended tablespaces ONLINE:
PROMPT ALTER TABLESPACE <ts_name> ONLINE;
PROMPT - If ORA-01190 after RESETLOGS for a file:
PROMPT RECOVER DATAFILE <file#>;
PROMPT ALTER DATABASE DATAFILE <file#> ONLINE;
PROMPT ==============================================================
PROMPT FINAL NOTES
PROMPT ==============================================================
PROMPT - PASS when: all intended datafiles are consistent (no FUZZY), at intended checkpoint,
PROMPT required archivelogs identified, and no unintended OFFLINE/DISABLED files.
PROMPT - Review alert.log during and after OPEN RESETLOGS for dictionary messages and errors.
PROMPT - For SYSTEM/UNDO inconsistencies or lost logs, consult Oracle Support before proceeding.
