To configure a DSS group, you add a DSSGROUP section to the Gateway daemon configuration file. The DSSGROUP section defines the group name, the CICS® servers that belong to the group, and the algorithm that CICS Transaction Gateway uses to select a CICS server within the group.
Each DSSGROUP section within a Gateway daemon configuration must have a unique name, otherwise the configuration is non-valid and the Gateway daemon fails to start.
