Oracle 10.2.0.4:
I have function based index something like
CREATE INDEX IDX_SENDER_EMAIL ON SENDER (UPPER(SENDER_EMAIL))
ASH is reporting high db file sequential read on this index, so I am trying to create a hash partition on this index. When I do that I get error.
ORA-30555: global index partitioning key is an expression
Is there a way to create hash partition using function based index? What options do I have?
