Remote Cloning Non-CDB
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 service database have compatible database character sets and national character sets.
You can use the remote cloning method to copy an Oracle Database 12c non-CDB on-premises database to a PDB in an Oracle Database 12c database on the Databaseservice.
Migration Tasks
To migrate an Oracle Database 12c non-CDB database to a Database service database deployment using the remote cloning method, you perform these tasks:
-
On the on-premises database host, invoke SQL*Plus and set the on-premises database to
READ ONLY
mode. -
On the Database service compute node, invoke SQL*Plus and create a database link that enables a connection to the on-premises database.
-
On the Database service compute node, execute the
CREATE PLUGGABLE DATABASE
command to clone the on-premises non-CDB database. -
On the Database service compute node, execute the
$ORACLE_HOME/rdbms/admin/noncdb_to_pdb.sql
script. -
On the Database 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 database back to
READ WRITE
mode.
