12c: Using DBFS

Oracle 12c introduces HTTP/HTTPS, FTP and WebDAV access to DBFS via the "/dbfs" virtual directory in the XML DB repository.

12c: Plugging unplugging Database

1- Unplugging the PDB

To unplug a PDB, you first close it and then generate an XML manifest file. The XML file contains information about the names and the full paths of the tablespaces, as well as data files of the unplugged PDB. The information will be used by the plugging operation.

12c: Working with Oracle Multitenant

Working with Oracle Multitenant
Environment: Oracle Database 12c (12.1.0) Installed on Windows 7

Creating a CDB creates a service whose name is the CDB name. As a side effect of creating a PDB in the CDB, a service is created inside it with a property that identifies it as the initial current container. The service is also started as a side effect of creating the PDB. The service has the same name as the PDB. Although its metadata is recorded inside the PDB, the invariant is maintained so that a service name is unique within the entire CDB.

12c: Configure EM Database Express HTTP port

In case you want to change default port of 12c EM Database Express, you need to configure the port using the dynamic protocol registration method. After the HTTP port is configured, you use it to access Enterprise Manager Express.
