Forecasting

Does the average DBA know how much more storage space will be needed in six months on a particular SQL Server or SAN that serves database servers? Can that DBA easily tell if a certain production server is going to hit its RAM wall next month? These answers can only be gained through the use of intelligent forecasting. Forecasting, of course, is impossible to do without historically gathered data, so this step relies completely on the previous step of Analysis being carried out.

According to Gartner, only 10% of database professionals are actually engaged in the process of forecasting, which means few are really being responsible in their attempts to understand the future needs of their critical database systems.

Tuning

Monitoring and Tuning are likely the two most practiced disciplines in the performance lifecycle. This can be unfortunate for the health of the database, as tuning often relies on understanding stress tests as well as historically gathered performance data. Although there are certainly many items that can be tuned on a database server, the three most frequently visited areas are:

  • Configuration.

  • SQL Code.

  • Physical Design.
