CREATE INDEX statementUse the CREATE INDEX statement to create an index for one or more columns in a table, or on values returned by a UDR that uses column values as arguments.
FRAGMENT BY Clause for IndexesUse the FRAGMENT BY clause to create a detached index and to define its fragmentation strategy across dbspaces or partitions.
Fragmentation of Unique Indexes

Fragmentation of Unique Indexes

You can fragment unique indexes on a table that uses a round-robin or an expression-based distribution scheme, but any columns referenced in the fragment expression must be indexed columns. If your index fragmentation strategy violates this restriction, the CREATE INDEX statement fails, and work is rolled back.
