Use this page to define the name and value of a WebSphere Application Server substitution variable.

Configuration tab

Name
Specifies the symbolic name for a WebSphere Application Server variable. For example, a variable name might represent a physical path or URL root that is used by WebSphere Application Server.

WebSphere variables are used for:

  • Configuring WebSphere Application Server path names, such as JAVA_HOME, and APP_INSTALL_ROOT.
  • Configuring certain cell-wide customization values.

WebSphere Application Server substitutes the symbolic name wherever its value appears in the system.

For example, "JAVA_HOME" is the symbolic name representing the file system path to the installation directory for the Java Virtual Machine (JVM). For example, the value is /opt/IBM/WebSphere/AppServer/java for the WebSphere Application Server product on a Linux machine.

You can create new variables for use in WebSphere Application Server components that support the use of variables.

The WebSphere Application Server security component supports variables when establishing global security, but only the following:

  • APP_INSTALL_ROOT
  • WAS_INSTALL_ROOT
  • USER_INSTALL_ROOT
  • WAS_TEMP_DIR
  • WAS_PROPS_DIR
  • WAS_ETC_DIR
The security component uses these variables as security defaults when making substitutions that identify a path to the security configuration settings.

Data type String
Value
Specifies the value that the symbolic name represents, such as absolute file path.

For example, the value might be the absolute file path, C:\WebSphere\AppServer\config, in the base WebSphere Application Server product on a Windows system. The corresponding symbolic name might be "CONFIG_ROOT."
