In the event your Produce DATABASE assertion fails, and if you didn't comprehensive Phase 7, then guarantee that there is not a pre-current server parameter file (SPFILE) for this instance that's environment initialization parameters in an unpredicted way. As an example, an SPFILE contains a setting for the entire route to all Handle documents, and the Generate DATABASE statement fails if All those Management files usually do not exist.
The next example results in a server parameter file from textual content initialization parameter file /u01/oracle/dbs/init.ora. In this instance no SPFILE identify is specified, Therefore the file is established Together with the System-certain default title and site proven in Desk two-3.

This segment describes the methods necessary to generate just one CloneDB database and uses these sample databases and directories:
Utilize the Generate TABLE statement: This command defines the structure within your desk, specifying its title along with the columns it will contain.
It's also possible to offer the file title and route for equally the PFILE and SPFILE if You aren't using default names and destinations.
