Sigma Web Framework Parms tab

The Sigma Framework Parms screen allows an administrator to configure various parameters for the Sigma Framework. This includes a standard list of parameter values, as well as possibly other parameters added by users. This screen is accessed after login by clicking on the System tab, and then clicking the Parms tab (as needed.) The Parms screen is available ONLY to users who have been given admin rights to the system. Otherwise, attempting to access this screen will result in a Permission Denied screen.

The Parms screen is depicted below.

The Parms screen is a standard Sigma dialog. To edit parameter entries, the user clicks the Edit button, modifies the parameter, and then clicks the Commit button on the edit screen. The user can restore the preset default configuration by clicking on the Default button on the edit screen. If the Default button is accidentally clicked, the user can inspect the previous settings by clicking the Back button of the browser.

The following parameters are supported. (Other parameters may also exist, depending upon the Framework applications that are supported.)

• CGI Timeout Seconds. This is the maximum time, in seconds, which the system will wait when generating a screen before displaying a Timeout indication. This setting is useful in preventing errant applications from permanently hanging on the system.
• Nav Tab On Color. This is a standard HTML color, or hexadecimal code, indicating the color of navigation tabs that are currently selected on the system. The value can be a standard color (such as blue) or a hexadecimal value in standard RRGGBB format.
• Nav Tab On Text. This is a standard HTML color, or hexadecimal code, indicating the color of selected navigation tab text, which should be selected to contrast with the Nav Tab On Color, described above.
• Nav Tab Off Color. This is a standard HTML color, or hexadecimal code, indicating the color of navigation tabs that are not selected on the system. The value can be a standard color (such as blue) or a hexadecimal value in standard RRGGBB format.
• Nav Tab Off Text. This is a standard HTML color, or hexadecimal code, indicating the color of selected navigation tab text, which should be selected to contrast with the Nav Tab Off Color, described above.
• Default User Access. This is the access for any user that is defined by the HTTP server, but not by the Sigma framework. This permits the administrator to implement IIS Windows Directory authentication, and disable any user who is not authorized to use the Sigma system. Or, the administrator can set the default user to Guest, and permit any user (registered with IIS or Apache) to access the system with a Guest access. In this situation, any user login that is specifically Disabled will still be denied access.
• System Email Contact. This is the system contact for the Sigma administrator or work group. The value can be used in framework screens, but is not required or used by the core Sigma Framework system.

Note that the above parameters affect the performance of the entire screen, and apply to all users of the Sigma Framework system.
