A cold backup method is the fastest way of duplicating any oracle database and creating its replica. Here I am going to create a new database with separate DB NAME using a source database.
Also, the source database is a CDB with 1 PDB attached but it won't make that much of difference for non-cdb databases as well. It's just few less actions for non-cdb.
Prerequisites:
- pfile backup of source database
- controlfile backup as trace from source database
- source datafiles copy when database is in mount/shutdown state. Do not copy a source database when it's running.
