Issue/Introduction

Are the I/O rates on the BUFRDWRS panel actually DASD I/O or SQL SELECT/UPDATE/etc?

Environment

Release:
Component: CIDB

Resolution

The “I/O Per Second” field is only for read I/Os, but it is only for physical i/o to dasd (including prefetch). So it is partially what you want. Write I/O would be needed to get a complete I/O rate.
