Resolution:
Each GridServer Manager requires a valid license to function. Licenses are limited by date, hostname, and number of Engines. By default, a demo license for four Engines is included with each Manager, but for further evaluation or production use, you must obtain a license by contacting DataSynapse Support.

You can view your Manager's license information in the GridServer Administration Tool, by going to the Admin tab and selecting the License Information page.

A Manager license consists of a single XML file, and is typically sent by DataSynapse Support via email as an attached file. They can also be downloaded at any time from the http://customer.datasynapse.com customer support site. You can inspect the license with a text editor to determine its capacity, but you should not make changes to the file.

To install the license:

   1. In the GridServer Administration tool, on the Admin tab, go to the License Information page.
   2. Copy the .ser file that was an attachment in your email message from DataSynapse or from a download from the DataSynapse customer support site to a location accessible with your web browser (either a local directory or a shared directory.)
   3. Click Browse.
   4. Find the license file and click Open.
   5. Click Upload New License.

If the license file is valid, it will overwrite the existing license and changes will take place immediately. If it is expired, corrupt, or otherwise not valid, an error message will appear and your existing license will remain in place.
