22 -- Definition: This function verifies Schema based XMLType tables that are
23 -- part of the transport set are self contained. i.e. the out of
24 -- line pieces that the table points to are also part of the
25 -- transport set. This will ensure that the SB XMLType table is
26 -- self contained.

44 -- Description: Verifies that all token manager tables for XML tables and columns
45 -- with binary storage (CSX) are also contained in the transported
46 -- tablespaces. This is needed so that data at the import site can be
47 -- decoded without a full remapping.

49 -- To be combined with verify_XMLSchema.

52 -- fromExp - being called by export?

68 -- Definition: This function verifies secondary objects that are associated
69 -- with an extensible index are contained in the list of
70 -- tablespaces or fully outside the list. This guarantees self
71 -- containment of all or none of the secondary objects
72 -- associated with the extensible index. For simple types like
73 -- tables and indexes it is clear why this check works. What may
74 -- not be so obvious is that this works even for objects like
75 -- partitions, lobs etc. For e.g. if Table T1 is partitioned
76 -- two ways P1 and P2, has a lob object L1 and Table T2 is an
77 -- IOT, and extensible index E1 is associated with L1 and T2
78 -- then it is sufficient just check that tablespace(L1) and
79 -- tablespace(T2) are either fully contained or fully out of
80 -- the tts set. Self Containment of T1 and T2 is guaranteed by
81 -- the straddling_rs_objects function
82 --
83 -- Inputs: fromexp - stop after first violation found
84 --
85 -- Outputs: None

88 -- for all other cases (even if violations have been found).

94 --++
95 -- Definition : This function verifies that:
96 -- 1. Materialized view logs stored as tables and the
97 -- corresponding master tables are self contained. The
98 -- containment check is similar to tables and its indexes:
99 -- If full_check is TRUE, then BOTH the MV log and the
100 -- master table must be in or both must be out of the
101 -- transportable set. If full_check is FALSE, then it is ok
102 -- for the MV log to be out of the transportable set but it
103 -- is NOT ok for the MV log to be in and its master table to
104 -- be out of the set.
105 -- 2. Updateable Materialized view tables and their
106 -- corresponding logs are fully contained in the
107 -- transportable set.
108 --
109 -- If fromExp is false, populate the violation table with the
110 -- offending violation object information for each violation.
111 --
112 -- Note that it is ok to transport just the MVs and not their
113 -- masters or vice versa. It is also ok to just transport
114 -- master tables without the mv logs, but NOT vice versa.
