ARCHIVED: Configure ArcGIS for license service failover at IU

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.

Note:

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.

To configure ArcGIS for license service failover:

From either the desktop or the Start menu, right-click My Computer, and then select Properties.
Click the Advanced tab, and then Environment Variables.
To add a variable, under "System variables", click New. The "New System Variable" window will appear:
In the "Variable name" field, enter:
```
  ARCGIS_LICENSE_FILE
```
In the "Variable value" field, enter:
```
  27004@esri1.uits.indiana.edu;27004@esri2.uits.indiana.edu;
```
Note:

The semicolon (;) at the end of the variable value is essential.
To close each of the open windows, click OK.

To verify the license server variable is set correctly:

From the Start menu, select All Programs or Programs, then Accessories, and then Command Prompt.
In the window that opens, at the prompt, enter:
```
  set ARCGIS_LICENSE_FILE
```
If the variable is set correctly, you should see the following statement in return:
```
  ARCGIS_LICENSE_FILE=27004@esri1.uits.indiana.edu;27004@esri2.uits.indiana.edu;
```
