SQL Server Tips by Burleson |
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.
