ClauseQuestionYesNo
STORAGE

Do you want to limit the amount of storage that the PDB can use?
Specify a 
STORAGE
 clause with the appropriate limits.
Omit the 
STORAGE
 clause, or specify unlimited storage using the 
STORAGE
clause.
DEFAULT
 
TABLESPACE

Do you want to specify a default permanent tablespace for the PDB?
Specify a 
DEFAULT
 
TABLESPACE
clause
with the appropriate limits.

Oracle Database creates a smallfile tablespace and subsequently will assign to this tablespace any non-
SYSTEM
 users
for whom you do not specify a different permanent tablespace.
Omit the 
DEFAULT
 
TABLESPACE
clause.

If you do not specify this clause, then the 
SYSTEM
 tablespace is the default
permanent tablespace for non-
SYSTEM
 users. Using the 
SYSTEM
 tablespace
for non-
SYSTEM
users is not recommended.
PATH_PREFIX

Do you want to use a 
PATH_PREFIX
 clause to ensure that all relative directory
object paths associated with the PDB are treated as relative to the specified directory or its subdirectories?

The 
PATH_PREFIX
 clause is ignored when absolute paths are used for directory
objects.

The 
PATH_PREFIX
 clause does not affect files created by Oracle Managed Files.
Include a 
PATH_PREFIX
 clause that specifies an absolute path.
Set the 
PATH_PREFIX
 clause to 
NONE
 or
omit it.
FILE_NAME_CONVERT

Do you want to use a 
FILE_NAME_CONVERT
 clause to specify the target locations
of the files?

The source files are the files associated with the seed.
Include a 
FILE_NAME_CONVERT
clause that specifies the target locations of
the files based on the names of the source files.
Omit the 
FILE_NAME_CONVERT
clause.

Use one of these techniques to specify the target locations of the files:

CREATE_FILE_DEST
 clause

Enable Oracle Managed Files for the CDB for it to determine the target locations.

Specify the target locations in the 
PDB_FILE_NAME_CONVERT
initialization parameter.

See "File
Location of the New PDB".
CREATE_FILE_DEST

Do you want to use a 
CREATE_FILE_DEST
 clause to specify the Oracle Managed
Files default location for the PDB's files?

The source files are the files associated with the seed.
Include a 
CREATE_FILE_DEST
clause that specifies the default file system directory
or Oracle ASM disk group for the PDB's files.
Omit the 
CREATE_FILE_DEST
clause.

Use one of these techniques to specify the target locations of the files:

FILE_NAME_CONVERT
 clause

Enable Oracle Managed Files for the CDB for it to determine the target locations.

Specify the target locations in the 
PDB_FILE_NAME_CONVERT
initialization parameter.

See "File
Location of the New PDB".
TEMPFILE REUSE

Do you want to reuse the temp file if a temp file exists in the target location?
Include the 
TEMPFILE REUSE
clause.
Omit the 
TEMPFILE REUSE
 clause.

Ensure that there is no file with the same name as the new temp file in the target location.
USER_TABLESPACES

Do you want to specify which tablespaces are included in the new PDB and which tablespaces are excluded from the new PDB?

This feature is available starting with Oracle Database 12c Release 1 (12.1.0.2).
Include the 
USER_TABLESPACES
clause and specify the tablespaces that are included
in the new PDB.
Omit the 
USER_TABLESPACES
clause.
logging_clause
Do you want to specify the logging attribute of the tablespaces in the new PDB?

This feature is available starting with Oracle Database 12c Release 1 (12.1.0.2).
Include the logging_clause.
Omit the logging_clause.
ROLES

Do you want to grant predefined Oracle roles to the 
PDB_DBA
 role locally
in the PDB?

The new administrator for the PDB is granted the 
PDB_DBA
 common role locally
in the PDB. By default, the 
CREATE
 
PLUGGABLE
 
DATABASE
statement
does not grant the administrator or the role any privileges.
Include the 
ROLES
 clause and specify the predefined Oracle roles to grant
to the 
PDB_DBA
 role. The specified roles are granted to the 
PDB_DBA
 role
locally in the PDB. The user who runs the 
CREATE
PLUGGABLE
 
DATABASE
 statement
does not need to be granted the specified roles. See Oracle
Database Security Guide for information about predefined Oracle roles.
Omit the 
ROLES
 clause.
