Single point of failure

asked on June 16, 2014

A client of ours found one of the key benefits of going to Rio to be the ability to have a live secondary server online in the event the primary server went down. While I realize the server only checks in with the license manager every so often I'd rather not bank on luck that we just checked in. According to the documentation "You should install only one License Manager Server for your Laserfiche Rio installation" This means we still have a single point of failure and loosing the license manager can take the whole system offline. Unless I'm missing something shouldn't there be a way to maintain a licensed backup so we aren't putting all our eggs in once basket?

Missing one check in will not cause your Server to go down - it will allow missed checks for a period of time, to account for temporary glitches, weekend downtime, that sort of thing. So you don't need to worry about it happening the check the moment when the failover is happening.

I'm aware it will allow for a missed check in or two by my concern is if the License Manager requires checkins every X days and the LM happens to fail X days minus an hour since the last check in the servers wont be validated for very long and finding a LM replacement even if it is backed up may not happen soon enough. Being this clients primary concern was having a secondary server available should the one fail I was just playing out every scenario that could stop all servers from being available. Can there be a fail over License Manager?

Was there ever an answer to this? I'm currently dealing with this same issue. The other concern I have is that if you have all windows users and the LFDS is offline won't they not be able to log in?

Yes, if the LM is down for the entire duration and the Server cannot reach it, it may experience issues. That's the point of the checkin in the first place - it needs to be able to communicate with it during the time period. The duration should be plenty of time to deal with issues though if something comes up.

Logging in through windows users is not an issue, as that information is passed along to the Laserfiche Server. The Laserfiche Server does not route every login attempt through LFDS.
