2.4.2 Replicating Server Groups in the Production Application

This section describes how the Production sample application replicates server groups. For an introduction to this feature, see Replicating Server Groups.

The following figure shows the Production sample application groups replicated on another machine, as specified in the application’s UBBCONFIG file, as ORA_GRP2 and APP_GRP2.

Figure 2-2 Replicating Server Groups Across Machines

In following figure, the only difference between the content of the groups on Production Machines 1 and 2 is the database:

• The database on Production Machine 1 contains student and account information for students with IDs between 100001 and 100005.
• The database on Production Machine 2 contains student and account information for students with IDs between 100006 and 100010.

Note:

The course information table in both databases is identical.

The student information in a given database may be completely unrelated to the account information in the same database.

For more information about how the Production sample application uses factory-based routing to distribute the application’s processing load across multiple machines, see Scaling with Factory-based Routing.
