A DB2 database environment can consist of a single installation of DB2 on one computer, or multiple installations of DB2 on multiple computers, all of which work collectively in a partitioned database environment.

Choose a non-partitioned database environment if you are installing DB2 on a single computer or if you do not have the appropriate license to install a partitioned environment.

In a partitioned database environment, the first partition is created when DB2 is installed on the first computer. This partition becomes the instance-owning partition. All subsequent partitions are added to the instance when DB2 is installed on them. As you install DB2 on other machines to create new partitions, these partitions are added to the instance.

In a partitioned database environment, partitions work collectively to manage data and handle client requests. The fact that databases are partitioned is transparent to users and applications. Typically, each partition is located on a different computer. Another possible configuration is one in which more than one partition runs on the same computer and participates in the same instance. This is known as running multiple logical partitions. For more information, see the DB2 Quick Beginnings for DB2 Servers book.
