Name

Symbolic name for a WAS variable. For example, a variable name might represent a physical path or URL root that is used by WAS. WAS variables are used for:

  • Configure WAS path names, such as JAVA_HOME, and APP_INSTALL_ROOT.

  • Configure certain cell-wide customization values.

WAS substitutes the symbolic name wherever its value displays in the system.

[Linux] For example, JAVA_HOME is the symbolic name representing the file system path to the installation directory for the JVM. For example, the value is...

/opt/IBM/WAS/AppServer/java

...for the WAS product on a Linux machine.

You can create new variables for use in WAS components that support the use of variables.

When establishing administrative security, the security component only supports the following variables:

  • 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

Specify the value that the symbolic name represents. For example, the value might be an absolute path value for a file or URL root.

[Linux] For example, /opt/IBM/WAS/AppServer/java is the value on a Linux machine for a variable named JAVA_HOME.
