RDBPROD: What are optimal sorted index node sizes based on page size (Doc ID 875975.1)

Last updated on FEBRUARY 01, 2018

Applies to:

Oracle Rdb Server on OpenVMS - Version 7.0 and later
HP OpenVMS Alpha
HP OpenVMS Itanium
HP OpenVMS VAX


Goal

The goal of this document is to determine the optimal node size for a sorted index that is unique and/or sorted ranked. If it is not unique and not sorted ranked, the article only partly applies. It gives only the numbers for an optimal use of the space on a page.

Locking problems and the maximum index depth are a different issue.

This document does not apply to hashed indexes.
