■ SQL*Plus▪ SQL> CREATE PLUGGABLE DATABASE…FROM

■ DBCA▪ dbca –createPluggableDatabase

■ Third-party tools▪ Delphix

Cloning using SQL Commands

■ Source database should be in READ ONLY mode

▪ Downtime (Clone from Standby Database)

— Thanks Franck

■ Create PDB from Source

■ Create Thin Clone from Source

▪ CREATE PLUGGABLE DATABASE PDB2 FROM PDB1 SNAPSHOT COPY

▪ Near Instantaneous space efficient copies

▪ ACFS, ZFS, CLONEDB, Third party storage

Clone local PDB from source PDB

Cloning using SQL Commands

■ CREATE PLUGGABLE DATABASE <CLONE> FROM <SOURCE>

▪ FILE_NAME_CONVERT

▪ CREATE_FILE_DEST

▪ DB_CREATE_FILE_DEST

▪ PDB_FILE_NAME_CONVERT

▪ STORAGE

▪ TEMP_FILE_REUSE

Clone local PDB from source PDB

Cloning using SQL Commands

■ Other Options

■ EXCLUDE TABLESPACES

■ METADATA ONLY

Clone PDB from source PDB

Cloning using SQL Commands

SQL> CREATE PLUGGABLE DATABASE SOECDB2 FROM SOE@CDB2TOCDB1

2 create_file_dest='/opt/oracle/oradata';

SQL> alter pluggable database SOECDB2 open;

Warning: PDB altered with errors.

Clone PDB from remote source PDB

Cloning using SQL Commands

SQL> select con_id,name,open_mode

2 from v$pdbs;
