Symptoms

Adding a Tablepace / Datafile in Primary Database causes the MRP in Physical Standby Database to terminate with the Error below. STANDBY_FILE_MANAGEMENT = MANUAL is set on the Standby Database.

In Unix Environment you will get the below Message when try to restart the MRP

Cause

This Error occurs if we add a Datafile OR Tablespace in PRIMARY Database and that could not be translated to the Standby Database due to these Reasons:

* Standy_file_management is set to MANUAL
* Primary & Physical Standby are having different file structures and DB_FILE_NAME_CONVERT is not set according to the Directory Structures in Primary and Standby

The Redo Log generated from Primary will have Information about the Tablespace / Datafile added however it could not be created successfully in Physical Standby Database due to the standby_file_management = MANUAL
or is not able to find the specified Folder due to a missing / incorrect Filename Conversion.
The File Entry is added to Standby Controlfile as "UNNAMED0000n" in /dbs or /database
folder depends on the Operating System and eventually the MRP terminates.



Alert Log in Standby Shows MRP is terminated with below error
=================================================================
File #5 added to control file as 'UNNAMED00005' because
the parameter STANDBY_FILE_MANAGEMENT is set to MANUAL
The file should be manually created to continue.
