GAS Configuration File Overview

The Genero Application Server is configured through a configuration file. The default configuration file is the as.xcf file, located in the $FGLASDIR/etc directory. You can create a separate Genero Application Server configuration file by creating a copy of the as.xcf file and making your modifications to the copy. You can specify which configuration file to use when starting the Genero Application Server by using the "-f" option. For more information about starting the Genero Application Server, refer to the Genero Application Server Overview section in this manual.

The configuration file is written using XML. The document consists of elements, the boundaries of which are either delimited by start-tags and end-tags, or, for empty elements, by an empty-element tag. Each element has a type, identified by name, sometimes called its "generic identifier" (GI), and may have a set of attributes. Each attribute specification has a name and a value.

The top-most element in the Application Server configuration file is the CONFIGURATION element. The CONFIGURATION element is the root element for all Genero configuration files. A configuration file will have one CONFIGURATION element which serves as the global configuration element. There are no attributes available for the CONFIGURATION element.

The CONFIGURATION element contains a single child element, the APPLICATION_SERVER element. The Application Server configuration starts with this element.

Syntax:

<CONFIGURATION>
  <APPLICATION_SERVER>
    <RESOURCE_LIST>
      ...
    </RESOURCE_LIST>
    <COMPONENT_LIST>
      ...
    </COMPONENT_LIST>
    <INTERFACE_TO_CONNECTOR>
      ...
    </INTERFACE_TO_CONNECTOR>
    <INTERFACE_TO_DVM>
      ...
    </INTERFACE_TO_DVM>
    <LOG>
      ...
    </LOG>
    <FILE_TRANSFER>
      ...
    </FILE_TRANSFER>
    <AUTHENTICATION>
      ...
    </AUTHENTICATION>
    <APPLICATION_LIST>
      ...
    </APPLICATION_LIST> 
    <SERVICE_LIST>
      ...
    </SERVICE_LIST>
  </APPLICATION_SERVER>
</CONFIGURATION>

Notes:

The APPLICATION_SERVER element contains the following child elements:

  1. One RESOURCE_LIST element, containing a list of resources.
  2. One COMPONENT_LIST element, containing a list of components.
  3. One INTERFACE_TO_CONNECTOR element, specifying the interface between the Genero Application Server (GAS) and the GAS Connector. The connector is either the CGI connector (fglccgi), the ISAPI filter (fglcisapi), or the user agent through direct connection.
  4. One INTERFACE_TO_DVM element, specifying the interface to the Dynamic Virtual Machine.
  5. Zero or more LOG elements, specifying the type of information that is logged and where it is logged to.
  6. Zero or more FILE_TRANSFER elements, specifying the directory where files are stored while being transferred between the front-end machine and the DVM.
  7. Zero or one AUTHENTICATION element, specifying authentication parameters.
  8. Zero or one APPLICATION_LIST element, containing a list of applications.
  9. Zero or one SERVICE_LIST element, containing a list of Web Services.
