During the creation of a pluggable database (PDB) from an existing PDB on Oracle Managed Files (OMF), users can edit the database location in the Oracle Database Configuration Assistant (DBCA) user interface. This allows users to change the location of the database files during PDB creation, giving an impression that the location can be changed. This behavior is incorrect because the PDB is always created with the database files in the same location as the source PDB, and the database location cannot be modified.

Workaround:

Do not edit the default database location value. Oracle Managed Files (OMF) creates the new PDB with the default database location value only.
