RDF and Curve provide a number of hooks for running customized computation at certain points of the batch process.
Generate is an RDF utility that runs the RDF batch, such as generating profiles, generating source level forecasts, and approving forecasts. Often, some customized computation is needed during the running of generate. For instance, after the generation of forecast and prior to the forecast approval, you may want to run some rules to compute the value of the approval alerts.
Curvebatch is a Curve utility that runs profile generation batch, such as range data source, generate source level profiles, and merge profiles.
This appendix details these topics:
There are several hooks provided in the RDF Generate and Curvebatch utilities so that custom expressions can be run at various predefined phases of the batch.
The hooks listed in the following tables are defined in the appcust.xml file.
Each phase of the batch cycle begins and ends with a hook that links to the next phase. Table F-1 lists and describes the RDF batch phases along with its hooks. These hooks are provided in the RDF Generate utility and defined in the appcust.xml file as shown in Figure F-1.

Each phase of the batch cycle begins and ends with a hook that links to the next phase. Table F-2 lists and describes the Curve batch phases along with its hooks. These hooks are provided in the Curvebatch utility and defined in the appcust.xml file as shown in Figure F-2.

The hooks listed in "Hooks" are defined in the appcust.xml file. For the setup directory of each domain, appcust.xml must be included.
The format of the RDF appcust.xml file is shown in Figure F-1.
The format of the Curve appcust.xml file is shown in Figure F-2.
