Listing 3-8 shows how the INTERFACES section extends the Bankapp sample application to use factory-based routing. The sample included with the BEA Tuxedo software does not contain these parameter settings.

Bankapp Sample INTERFACES Section

*INTERFACES
        "IDL:BankApp/Teller:1.0"
         FACTORYROUTING=atmID
*ROUTING
     atmID
            TYPE = FACTORY
            FIELD = "atmID"
            FIELDTYPE = LONG
            RANGES = "1-5:BANK_GROUP1,
                      6-10: BANK_GROUP2,
                      *:BANK_GROUP1
*GROUPS
      SYS_GRP
             LMID        = SITE1
                  GRPNO       = 1
      BANK_GROUP1
                  LMID        = SITE1
                  GRPNO       = 2
      BANK_GROUP2
                  LMID        = SITE1
                  GRPNO       = 3

In this example, the IDL:Bankapp/Teller interface employs a factory-based routing scheme called atmID, as defined in the ROUTING section. The example indicates that the processing will be distributed across the following two server groups:

BANK_GROUP1 processes interfaces used by the application when the atmID field is between 1 and 5 (inclusive), or greater than 10.
BANK_GROUP2 processes interfaces used by the application when the atmID is between 6 and 10, inclusive.
