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 1-4lists the DB2 9.5 hardware requirements for various platforms.
