This section provides information about creating a new PDB by cloning an existing PDB from a remote CDB using EM Express.
Note:
Before you create a new PDB by cloning an existing PDB from a remote CDB:
The source PDB (the PDB that you want to clone) must exist, and EM Express must be configured to access the PDB.
The source PDB must be open.
The target CDB (the CDB into which you want to plug in the cloned PDB) must exist, and EM Express must be configured to access the CDB.
The target CDB must be in read/write mode.
The target host user must be the owner of the Oracle home that the CDB belongs to.
To create a new PDB by cloning an existing PDB from a remote CDB:
In EM Express, navigate to the Containers page for the CDB in which you want to create the PDB.
For more information, see "Accessing the Containers Page."
In the Containers section of the Containers page, Remote Clone from the Actions menu. The Clone a Remote PDB wizard appears.
On the General page of the Clone wizard, supply values for these fields:
PDB Name: Enter the name you want to use for the PDB that will be created by the clone operation.
Source PDB Name: Enter the name of the PDB that you want to clone in the remote CDB.
DB Link: Enter the name of the database link for the remote CDB that contains the PDB to be cloned.
Click the right arrow button to go to the Storage page.
On the Storage page, select the type of location where you want to store the datafiles for the PDB:
If the target CDB (in which you are creating the PDB) is enabled with Oracle Managed Files and you want to use the same, then select Use Oracle Managed Files (OMF).
If the target CDB does not use OMF, then specify a datafile location or accept the default specified in the Datafile Location field.
Also on the Storage page, choose whether or not to enable unlimited storage for the datafiles.
If you do not enable unlimited storage, then you must specify values for these fields:
Max Size: The amount of storage that can be used by all tablespaces that belong to the PDB.
Max Shared Temp Size: The amount of storage in the default temporary tablespace shared by all PDBs that can be used by sessions connected to the PDB.
If no values are specified for these fields, then their values will be set to unlimited when the PDB is created.
If the target CDB to which you are cloning the remote PDB has a current active resource plan, the Resource Limits page appears.
Supply values for these fields, or keep the default values for the PDB you are creating:
Shares: Assign a new share value for this PDB, or keep the current value.
CPU Utilization Limit (%): Assign a new CPU utilization percentage value for this PDB, or keep the current value.
Parallel Server Limit (%): Assign a new parallel server utilization percentage value for this PDB, or keep the current value.
Click OK.
The PDB is created and opened in read/write mode. EM Express adds the PDB to the list of containers that appears in the Containers section on the Containers page.
