4. Clear Index
ALTER TABLE wrh$_enqueue_stat DROP CONSTRAINT wrh$_enqueue_stat_pk;

5. Create a constraint
ALTER TABLE Wrh$_enqueue_stat ADD (
CONSTRAINT WRH$_ENQUEUE_STAT_PK
PRIMARY KEY
(DBID, snap_id, Instance_number, Eq_type, Req_reason)
USING INDEX
Tablespace sysaux);

The next day, the same error, and then look at the beginning of the table WHR, found that the query results are inconsistent, and then all the constraints cleared, and then rebuilt, solved, ora-00600 problem
