2.6.4.1 Bug 27217146

During the creation of a pluggable database (PDB) from an existing PDB on Oracle Managed Files (OMF), you can edit the database location in the Oracle Database Configuration Assistant (DBCA) user interface. This enables you to change the location of the database files during PDB creation, implying that the location can be changed. This is incorrect because the PDB is always created with the database files in the same location as the source PDB, and you cannot modify the database location.
Workaround:
Do not edit the default database location value. OMF creates the new PDB with the default database location value only.
