Chapter 17: Maintenance Activities and Performance

This chapter explains both how maintenance activities can affect the performance of other Adaptive Server activities, and how to improve the performance of maintenance tasks.

Maintenance activities include such tasks as dropping and re-creating indexes, performing dbcc checks, and updating index statistics. All of these activities can compete with other processing work on the server.

Whenever possible,perform maintenance tasks when your Adaptive Server usage is low. This chapter can help you determine what kind of performance impacts these maintenance activities have on applications and on overall Adaptive Server performance.
