Configuration Variables

Setting Tango Options With Configuration Variables

Configuration variables set options controlling the operation of Tango Server. This chapter describes the configuration variables and also lists their default values and the scopes in which they are valid.

Configuration variables with scope other than system can be set just like any other variable: use the <@ASSIGN> meta tag with the SCOPE attribute set in HTML or in the Assign action when building an application file. See "Working With Variables" in Chapter 7 of the User's Guide for details of variable assignment.

To change system configuration variables, you must first set configPasswd with scope=USER to match the system configuration variable configPasswd, or you can use the config.taf application file to set system configuration variables more easily. See the chapter "Using Tango Server" in the User's Guide, and the Getting Started Guide for details.

Tango Server switches (for example, fileReadSwitch, javaSwitch) are special configuration variables that enable or disable certain Tango features. Documentation on Tango Server switches is provided in the User's Guide: see "Feature Switches" in the chapter "Using Tango Server" for details on these configuration variables.

Configuration variables are saved in the configuration file (t3server.ini on Windows and UNIX and Tango 3 Server Preferences under Mac OS). See the chapter "Using Tango Server" in the User's Guide for more details about this file.
