Chapter 1. Introduction to DB2 deployment 13
Client/server relationship
If DB2 servers are taking part in workload balancing, then determining the correct
number of client requests and workload would be essential to allocating sufficient
resource for a given environment.
When deploying an application that interacts with the DB2 database, one of the
key decisions that have to be made is whether or not it should reside locally with
the DB2 server. As with any decision, there are pros and cons that must be
weighed for each specific scenario.
Hardware and software considerations
Each DB2 version and product has specific minimal hardware and software
requirements. It is important to review current system specifications in a given
deployment setting to ensure that it meets DB2 requirements.
Table 1-4 lists the DB2 9.5 hardware requirements for various platforms.
