ORA-14279: index mismatch for tables in ALTER TABLE EXCHANGE SUBPARTITION
Cause: The two tables specified in the ALTER TABLE EXCHANGE SUBPARTITION have indexes which are not equivalent
Action: Ensure that the indexes for the two tables have indexes which follow this rule For every non partitioned index for the non partitioned table, there has to be an identical LOCAL index on the partitioned table and vice versa. By identical, the column position, type and size have to be the same.
