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.
