In addition to differences in features, each edition also sets different system limits. As shown in Table 1-6 on page 17, each edition has different CPU or PVU limits in addition to memory utilization limits set for DB2 operation. Therefore, when planning the DB2 server deployment, the planner must gather information regarding the potential workload.

Generalized workload capabilities of DB2 server products are shown in Figure 1-1.
