- E. The password file is automatically converted by RMAN.
- F. Databases can be transported between systems with different endian formats.
Answer: A,B,C
Explanation:
Explanation
A: If you do not provide a destination, then the DB_FILE_CREATE_DEST initialization parameter must be set in the target platform. RMAN restores the data files to the location specified by this parameter using new Oracle Managed File (OMF) names. BC: While creating the cross-platform backup to transport a database, you can convert the database either on the source database or the destination database. The benefit of performing the conversion on the destination database is that the processing overhead of the convert operation is offloaded from the source to the destination database.
