RMAN-05001: Auxiliary Filename Conflicts with a File Used by the Target Database Tips

Expert Oracle Database Tips by Donald BurlesonMarch 21, 2015

 

Question:  I am trying to clone a database using RMAN and I get the following RMAN-05001 error:  

RMAN-05001: auxiliary filename /xxx/xxx/xx.dbf conflicts with a file used by the target database tips

How do I fix the RMAN-05001 error?

Answer:  See here, how to clone a database with RMAN.

First, ALWAYS start by looking-up the RMAN-05001error message.  

Start by using the oerr utility to look-up the RMAN-05001 error:  

RMAN-05001 auxiliary filename string conflicts with a file used by the target database  

Cause: RMAN is attempting to use the specified file name as a restore destination in the auxiliary database, but this name is already in use by the target database.  

Action: Use the SET AUXNAME command to specify a name for the datafile that does not conflict with a file name in use by the target database

 The RMAN-00501 error is common if you are duplicating to a server with the same file directory structure.   As we see in the RMAN-00501 action, the recommended solution for the RMAN-05001 error is to use the configure auxname command:

configure auxname for datafile '/xxx/xxx.dbf' to '/yyy/xxx.dbf';

This RMAN-05001 error may also be a bug, and the workaround is to add the NOFILENAMECHECK option to the duplicate command.

duplicate target database for standby dorecover NOFILENAMECHECK;  

or  

duplicate target database to nofilenamecheck;

It is also important that you have set your init.ora parameter db_file_name_convert.  There should be an appropriate mapping between the primary's and standby's disk mount points using the parameter db_file_name_convert.  

The db_file_name_convert parameter is used to convert the filename on the primary database to a filename on the standby database.  

The value of this parameter should be set in a pair of strings. The first string should correspond to the filename pattern on the primary database and the next string to the filename pattern on the standby database.  

More than one pair can be specified if there is a need to accommodate more than one pattern in filename changes between the primary and the standby database.
