You can install multiple, separately operating HiRDB systems on one server machine. Such a system configuration is called a multi-HiRDB configuration. A multi-HiRDB configuration would be appropriate under the following circumstances:

• Running an operational system and a test system on the same server machine
• Running systems for different applications on the same server machine

Note, however, that you cannot combine HiRDB/Single Servers and HiRDB Parallel Servers in a multi-HiRDB system.

Figure 1-7 shows an example of a multi-HiRDB configuration implemented on a HiRDB/Single Server.

Figure 1-7 Multi-HiRDB configuration using HiRDB/Single Servers

Explanation

This is a multi-HiRDB configuration implemented on a HiRDB/Single Server.

HiRDB/Single Server 1 is designated as the operational system, and HiRDB/Single Server 2 serves as a test system.
