ORA-30392: the checksum analysis for the rewrite equivalence failed
Cause: the given checksum does not match with that generated from the source and destination statements.
Action: Verify the create safe rewrite equivalence statement to see if it has been modified.
ORA-30393: a query block in the statement did not rewrite

Action: Eliminate the redundant JOIN KEY clauses.
ORA-30398: illegal JOIN KEY clause
Cause: A JOIN KEY clause was specified that did not conform to certain requirements. A JOIN KEY clause connecting a child level with its non-immediate ancestor level is allowed only when that child level and its ancestor level satisfy the following conditions:
1. The immediate parent of the child level must be a skip level.

2. The child level cannot be a skip level.

3. The ancestor level must be a non-skip level.

4. The ancestor level must be the nearest non-skip level to the child level in the hierarchy.

Action: Modify the JOIN KEY clause so that it satisfies the conditions mentioned above.
ORA-30399: a skip level must have at least one column that allows NULL values
Cause: A SKIP clause cannot be specified with a level when all of the columns that make up the level have NOT NULL constraints.
Action: Drop the SKIP clause.
ORA-30400: identical JOIN KEY clauses
Cause: Two JOIN KEY clauses with identical child keys and parent levels were specified.
Action: Eliminate the redundant JOIN KEY clause.
