Managing Application Environment Variables

Manually Adding an Application Environment Variable

1. Log in to ServiceStage.
2. Choose Application Management.
3. Click the target application. The Overview page is displayed.

4. In the navigation pane on the left, click Environment Variables.
5. Select a created environment from the drop-down list.
6. Click Add Environment Variable and set Variable Name and Variable/Variable Reference.

   Where,

   • Variable Name is the name of an application environment variable and must be unique.
   • Variable/Variable Reference is the value of the application environment variable.

   For example, set Variable Name to User and Variable/Variable reference to admin. That is, when the program code reads the User environment variable, admin is obtained. For example, you can start subprocesses as the admin user and read files as the admin user. The actual execution effect depends on the code.

7. Click Submit.
