Hi to all,

Wanted to know if it's possible to increase performance during insertion, deletion or update in a table that contain indexes. If yes then how?

Thanks,

You may use the NOLOGGING Clause while inserting data into a table. Also you may like to disable constraints while doing Bulk loads.

The NOLOGGING clause also specifies that subsequent direct loads using SQL*Loader and direct load INSERT (ie +APPEND ) operations are not logged. Subsequent DML statements (UPDATE, DELETE, and conventional path insert) are unaffected by the NOLOGGING attribute of the table and generate redo.
