Name
DBMS_SNAPSHOT.REFRESH
Synopsis
Call the REFRESH procedure to force a snapshot refresh. The specifications for the Oracle7 and Oracle8 versions of the REFRESH procedure differ. Note that the Version 8.0 implementation adds parameters that support parallelism and drops the execute_as_user parameter. Both versions are overloaded, allowing you to specify the list of snapshots as a comma-delimited string in the list parameter or as a PL/SQL table in the tab parameter. The other parameters are identical for the two versions.
Oracle7 specification:

(list IN VARCHAR2,
method IN VARCHAR2 DEFAULT NULL,
rollback_seg IN VARCHAR2 DEFAULT NULL,
push_deferred_rpc IN BOOLEAN DEFAULT TRUE,
refresh_after_errors IN BOOLEAN DEFAULT FALSE,
execute_as_user IN BOOLEAN DEFAULT FALSE );
PROCEDURE DBMS_SNAPSHOT.REFRESH
(tab IN OUT dbms_utility.uncl_array,
method IN VARCHAR2 DEFAULT NULL,
rollback_seg IN VARCHAR2 DEFAULT NULL,
push_deferred_rpc IN BOOLEAN DEFAULT TRUE,
refresh_after_errors IN BOOLEAN DEFAULT FALSE,
execute_as_user IN BOOLEAN DEFAULT FALSE );Oracle8 specification:
