Data Pump Export
Here are some examples of how to use the exclude
option:
EXCLUDE=CONSTRAINT
will exclude all (non-referential) constraints except for NOT NULL
constraints.
EXCLUDE=GRANT
will exclude object grants on all object types and system privilege
grants.
EXCLUDE=USER
will exclude only the definitions of users, not the objects
contained within the user’s schemas.
EXCLUDE=SCHEMA:”=’HR’”
will exclude a specific user HR and all of the HR schema’s objects.
EXCLUDE=PACKAGE, FUNCTION, PROCEDURE
will exclude all packages, functions, and procedures associated with
this export.
flashback_scn
– This specifies the system change number (SCN) that the export uses
to enable the Flashback utility. The export operation is performed
with data that is consistent as of this SCN.
flashback_time – This will use a SCN that is
most closely matched to the specified time to enable the Flashback
utility. The export operation is performed with data that is
consistent as of this SCN.
include – This allows the fine-grained
specification of objects and object types that are to be included in
the export operation. The include and exclude parameter are
mutually exclusive.
You can use
either INCLUDE or EXCLUDE if you use CONTENT=DATA_ONLY, which
implies access to table rows only.
Here is an example of a parameter file for an
export operation that only includes views and procedures for schemas
HR and OE:
SCHEMAS=HR, OE
INCLUDE=VIEWS
INCLUDE=PROCEDURE
