Accessing Multiple Database Servers

Figure 20 shows a configuration with two database servers on host river. When more than one database server is active on one computer, it is known as multiple residency. (For more information about multiple residency, see Multiple Residency.)

For the configuration in Figure 20, you must prepare two ONCONFIG configuration files, one for database server A and the other for database server B. The sqlhosts file includes the connectivity information for both database servers.

The ONCONFIG configuration file for database server A includes the following line:

DBSERVERNAME            riverA_shm

The ONCONFIG configuration file for database server B includes the following line:

DBSERVERNAME            riverB_soc
