Figure 4-74 Example of retrieval processing with RDAREA names specified

[Figure]

Explanation:
This example performs retrieval processing on the row-partitioned table T1 that is stored in RDAREAs RD01, RD02, and RD03. Each of the three UAPs (AP1, AP2, and AP3) issues the SELECT statement specifying an RDAREA to be accessed. This method enables the RDAREAs to be accessed in parallel via the front-end servers FES1, FES2, and FES3, thereby distributing the load among the server machines where the UAP and front-end servers are located.
