At IU, how do I configure ArcGIS for license service failover?

At Indiana University, UITS manages a two-server Unix system to provide automated failover licensing support for Esri software. The primary and secondary UITS-managed Esri license servers are esri1 and esri2, respectively. To ensure uninterrupted access to the license service, UITS recommends that you configure your computer for license server failover by creating a system environment variable specifying the names and port numbers of the Esri license servers.

You must have administrative rights to make the following changes to your computer; log in as an administrator if necessary.

Indiana University policy Security of Information Technology Resources (IT-12) requires that you normally refrain from running your Windows computer as an administrator. For more, see About the principle of least privilege.

  2. Click the Advanced tab, and then Environment Variables.

  4. In the "Variable name" field, enter:
  5. In the "Variable value" field, enter:;;

To verify the license server variable is set correctly:
