The customer's Oracle11gR2ActiveDataGuard environment, the master database's standby_file_managementAUTO, the Standby database's standby_file_managementMA

The customer's Oracle 11gR2 Active Data Guard environment, master database standby_file_management = AUTO, slave database standby_file_management = MA

The customer's Oracle 11gR2 Active Data Guard environment, master database standby_file_management = AUTO, standby database standby_file_management = MANUAL ,, as a result, the operations on the data files added to the tablespace in the primary database are not synchronized to the backup database. The UNNAMED00003 file is not created in the $ ORACLE_HOME/dbs directory. The backup database has the following alarm logs:

File #3 added to control file as 'unnamed00003 'because
The parameter STANDBY_FILE_MANAGEMENT is set to MANUAL
The file shoshould be manually created to continue.

Completed: alter database recover managed standby database using current logfile disconnect from session

The key to solving this problem is to manually create a new data file. refer to the following content to solve the problem:

How to resolve MRP stuck issues on a physical standby database? (Documentation ID 1221163.1)

......

Solution 10 Add the new datafiles to the standby database manually.

1) Please take a hot backup of new datafiles from the primary database.

2) Create a new standby controlfile from the primary database

SQL> alter database create standby controlfile as '/tmp/controlf. ctl ';

If datafiles are on ASM, please follow the note below and you coshould ignore the rest of steps:

Note 734862.1 Step By Step Guide On How To Recreate Standby Control File
When Datafiles Are On ASM And Using Oracle Managed Files

Or you cocould modify the wrong datafile name in the standby controlfile by alter database rename command. For example,

SQL> ALTER DATABASE RENAME FILE' 'To' ';

3) If the new datafile location on the primary is different from the standby, please make sure
Db_file_name_convert init parameter is set on the standby database.

Note 47325.1 Init. ora Parameter "DB_FILE_NAME_CONVERT" Reference Note

If db_file_name_convert init parameter has already been set, then you cocould ignore this step.

4) Cancel the managed recovery

SQL> alter database recover managed standby database cancel;

5) set standby_file_management = manual on the standby database and shutdown the standby database.

SQL> alter system set standby_file_management = manual sid = '*';
SQL> shutdown immediate;
