About Table-Controlled Partitioning and Using Indexes
It is recommended that you use table-controlled partitioning with Siebel database tables.
In the current Siebel release, partitioned tables use table-controlled partitioning by default. If you use table-controlled partitioning, partitioning is defined at the table level so you do not require a partitioning index. Maintaining indexes that are used for partitioning purposes only is no longer necessary, which reduces storage requirements and allows you to select a secondary index as the clustering index.
