Redundant Sentinel License Manager unable to distribute commuter licenses if Primary server is not active. Network client commuter utility unable to start or presents error(s).

Technote (troubleshooting)


Problem(Abstract)


When the Primary server of a multi-server Sentinel License Manager redundancy is not active (on line), the redundancy cannot distribute commuter licenses.

Symptom

The network client Commuter Utility exhibits a number of different behaviors depending upon the product version including the Utility not opening and 'Initialization failed. Unable to connect Server.' error message.


Cause


Sentinel Network License Manager in a redundant configuration is only able to distribute commuter licenses from the 'Primary' server, which also acts as the Lead server when everything is working as expected.

This means that if the Primary Server in a redundant configuration goes down, the Secondary server will act as the Lead Server, but will not assume the role of the Primary server. Commute license information will only be retained by the Primary server and cannot be transferred.


Diagnosing the problem

Restoring the Primary server to active status corrects the behavior.


Resolving the problem

This behavior of Sentinel Network License Manager redundant server configurations has been reported to IBM SPSS Development. An enhancement request has been submitted to allow the distribution of commuter licences by the 'lead' server in a redundant server configuration (rather than just the Primary server).
