The name of the DataService.
The value for data-service must be a valid name from the DataService list registered to this NameServer, as defined by your appServiceName List entry in the broker properties file. If a default DataService has been defined for your broker instance, you can omit this parameter and connect using the default service.
This parameter must be used in conjunction with the DataServer Logging (-dslog) startup parameter.
Note: Using the -DirectConnect parameter on the CONNECT statement will override the -DataService parameter.
For more information on the CONNECT statement, see OpenEdge Development: ABL Reference.
