Adding Processors to a Machine

The first thing to be done is to ensure that you have installed one or more additional processors in your machine. To allow the DB2 database manager to take advantage of the new processors, there are configuration parameters that should be reviewed and perhaps updated. (Some operating systems, like Solaris, can dynamically vary processors on- and off-line.) The parameters that are used to determine the number of processors used and may need to be updated include:

You should also consider the parameters associated with applications that may need to be updated. Refer to "Parallel Processing of Applications" for more information.

Utilities in DB2 such as load, backup, and restore can take advantage of the additional processors. Refer to Chapter 6. "Utilities for Moving Data" and Chapter 7. "Recovering a Database" for information on these utilities.
