Troubleshooting Issues with vFabric GemFire Licenses

This section provides some basic troubleshooting on vFabric license installation.

Basic Troubleshooting Steps

If you install an invalid serial number or if GemFire is unable to obtain a dynamic license from the vFabric License Server, GemFire will fail to start and will throw an exception. In this case, depending on your licensing configuration, you may need to perform one of the following fixes:
  1. Replace the invalid serial number or serial numbers specified either in gemfire.properties or in serial number files with valid (non-expired) serial licenses, and restart the server.
  2. Completely remove the invalid serial number or serial numbers from gemfire.properties, and restart the server. When the server restarts, it will use the default evaluation license.
  3. Remove the keyword "dynamic" from gemfire.properties, and restart the server. When the server restarts, it will use the default evaluation license
  4. Increase the amount of time specified in license-server-timeout. This option is only applicable if you are running GemFire on a vSphere virtual machine and using the vFabric License Server to acquire licenses dynamically.
