ORA-19602: cannot backup or copy active file in NOARCHIVELOG mode

I got ” ORA-19602: cannot backup or copy active file in NOARCHIVELOG mode ”  error in Oracle database.

 

ORA-19602: cannot backup or copy active file in NOARCHIVELOG mode

 

Details of error are as follows.

database is running in NOARCHIVELOG mode. We need to check for corruptions so the database was brought down and mounted but RMAN validate failed with the below errors:

 

$ rman target /

cannot backup or copy active file in NOARCHIVELOG mode

This ORA-19602 is related to the NOARCHIVELOG mode and does not allow full database backups.

 

In 10g and below, when operating in NOARCHIVELOG mode, RMAN validate can only be executed against a MOUNTED database and datafiles that are not in need of recovery. RMAN validate cannot be executed against fuzzy datafiles when in noarchivelog, mounted mode.

To confirm the database and datafiles’ current status:

SQL> select dbid, name dbname, open_mode, database_role,
  2  to_char(created,'dd-Mon-YYYY hh24:mi:ss') created,
  3  to_char(resetlogs_time,'dd-Mon-YYYY hh24:mi:ss') resetlogs_time
  4  from v$database;

Recover the database first to ensure that all files are nolonger in need of recovery. Then run the RMAN validate.

 

RMAN> recover database;

RMAN> backup validate check logical database;

RMAN> alter database open;

SQL> select * from v$database_block_corruption.

 

 

Note: These restrictions are lifted in 11g. That is, as of 11g you will be able to run RMAN validate against an OPEN database when regardless of its ARCHIVELOG mode and datafiles’ status (FUZZY or NOT).

 

 

Sample Output in 10g:

 

RMAN> recover database;
