How To: Switch license servers for ArcIMS ArcMap Server
The ArcIMS ArcMap Server requires a license administered by a license server. The license server can be on a Windows or UNIX machine and can reside on the local machine or on a network. A registry key must exist that points to a functional license server. Instructions provided describe how to update the license registry key if license servers are switched.
Note: ArcMap Server looks for the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\ESRI\ARCIMS\LICENSE_SERVER = "@<license_server>"; for example, @myserver. This key is removed when the local license manager is uninstalled. If using a remote license manager and wish to install a local license manager, the installation procedure updates this key and points to the local machine automatically. Both the key and the value may be changed at any time.
Edit the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\ESRI\ARCIMS\LICENSE_SERVER
Determine if the key exists in the registry: A. Click Start > Run, type "regedit", and click OK to open the registry. B. On the left side of the registry window, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\ESRI\ARCIMS. C. Check in the right panel to see if a key named LICENSE_SERVER exists.
If the key does not exist, complete this step. Otherwise, skip to step 3. A. From the Edit menu select New and select String Value. B. Right-click New Value #1 and click Rename. Rename this key LICENSE_SERVER.
Edit the value of the registry key and set it equal to the name of the new license server: A. In the registry window, double-click the name license_ server to open the edit string dialog box. B. In the value data field, type the name of the new license server using the following format: @<server name>; for example, @myserver. C. Click OK and exit the registry editor. D.
