3.3.1 About the UBBCONFIG File in Distributed Applications

The UBBCONFIG file contains a description of either data-dependent routing (Oracle Tuxedo) or factory-based routing (Oracle Tuxedo CORBA), as follows:

• The GROUPS section is populated with as many server groups as are required for distributing the system. This allows the system to route a request to a server in a specific group. These groups can all reside on the same site (SHM mode) or, if there is networking, the groups can reside on different sites (MP mode).
• For data-dependent routing in Oracle Tuxedo, the SERVICES section must list the routing criteria for each service that uses the ROUTING parameter.

Note:

If a service has multiple entries, each with a different SRVGRP parameter, all such entries must set ROUTING the same way to ensure consistency for that service. A service can route only on one field, which must be the same for all the same services.

• For factory-based routing in Oracle Tuxedo CORBA, the INTERFACES section must list the name of the routing criteria for each CORBA interface that uses the FACTORYROUTING parameter. This parameter is set to the name of a routing criteria defined in the ROUTING section.
• Add a ROUTING section to the configuration file to show mappings between data ranges and groups so that the system can send the request to a server in a specific group. Each ROUTING section item contains an identifier that is used in the INTERFACES section (for Oracle Tuxedo ATMI) or in the SERVICES section (for Oracle Tuxedo).
