Evaluate the following command:
SQL>ALTER SYSTEM SET db_securefile = ‘IGNORE’;
What is the impact of this setting on the usage of SecureFiles?
A.
It forces BasicFiles to be created even if the SECUREFILE option is specified to create the
LOB.
B.
It forces SecureFiles to be created even if the BASICFILE option is specified to create the LOB.
C.
It does not allow the creation of SecureFiles and generates an error if the SECUREFILE option
is specified to create the LOB.
D.
It ignores the SECUREFILE option only if a Manual Segment Space Management tablespace is
used and creates a BasicFile.
DB_SECUREFILE specifies whether or not to treat LOB files as SecureFiles.
Values:
NEVER
Any LOBs that are specified as SecureFiles are created as BasicFile LOBs. All SecureFile-specific storage options and features (for example, compress, encrypt, deduplicate) will cause an exception. The BasicFile LOB defaults will be used for storage options not specified.
PERMITTED
LOBs are allowed to be created as SecureFiles.
ALWAYS
All LOBs created in the system are created as SecureFile LOBs. If the LOB is not created in an Automatic Segment Space Managed tablespace, then an error will occur. Any BasicFile LOB storage options are ignored. The SecureFile defaults will be used for all storage options not specified.
IGNORE
The SECUREFILE keyword and all SecureFile options are ignored.
