Remote Cloning a PDB
You can use this method only if the on-premises platform is little endian, the on-premises database release is 12.1.0.2 or higher, and the on-premises database and Database Classic Cloud Service database have compatible database character sets and national character sets.
You can use the remote cloning method to copy a PDB from your on-premises Oracle Database 12c database to a PDB in an Oracle Database 12c database on Oracle Database Classic Cloud Service.
To migrate an Oracle Database 12c PDB to a PDB in a Database Classic Cloud Service database deployment using the remote cloning method, you perform these tasks:
-
On the on-premises database host, invoke SQL*Plus and close the on-premises PDB and then reopen it in
READ ONLY
mode. -
On the Database Classic Cloud Service compute node, invoke SQL*Plus and create a database link that enables a connection to the on-premises database.
-
On the Database Classic Cloud Service compute node, execute the
CREATE PLUGGABLE DATABASE
command to clone the on-premises PDB. -
On the Database Classic Cloud Service compute node, open the new PDB by executing the
ALTER PLUGGABLE DATABASE OPEN
command. -
Optionally, on the on-premises database host invoke SQL*Plus and set the on-premises PDB back to
READ WRITE
mode.
