Hi:
Oracle 8173 on Sun Box.
SQL> select count(*) from user_tables;
COUNT(*)

SQL> select count(*) from user_segments where segment_type='TABLE';
COUNT(*)

SQL> select segment_name from user_segments
2 where segment_type='TABLE'
3 and segment_name like 'DR$%'
4 order by segment_name;
SEGMENT_NAME

DR$ABSTRACT_TEXT$I
DR$ABSTRACT_TEXT$R
DR$COREREF_ABSTRACT$I
DR$COREREF_ABSTRACT$R

DR$COREREF_TITLE$R
DR$TEST_CONTEXT$I
DR$TEST_CONTEXT$R

SQL> select table_name from user_tables

TABLE_NAME

DR$ABSTRACT_TEXT$I
DR$ABSTRACT_TEXT$K
DR$ABSTRACT_TEXT$N
DR$ABSTRACT_TEXT$R
DR$COREREF_ABSTRACT$I
DR$COREREF_ABSTRACT$K
DR$COREREF_ABSTRACT$N
DR$COREREF_ABSTRACT$R

TABLE_NAME
------------------------------
DR$COREREF_TITLE$R
DR$TEST_CONTEXT$I
DR$TEST_CONTEXT$K
DR$TEST_CONTEXT$N
DR$TEST_CONTEXT$R
16 rows selected.
Why tables like DR$ABSTRACT_TEXT$K, DR$ABSTRACT_TEXT$N do not have their
corresponding segments? What are they and their functions?
TIA.
