Lotus Traveler in cluster? new feature request
Vladislav Tatarincev 9 May 2011 12:36:44
Officially Lotus Traveler does not support cluster, but there are big organization who use Traveler, and need high availability.I wish there could be two servers configured in Traveler client, if one server is not responding, Traveler client tries another server.
I have read in documentation, that this could be cause high resource usage, since there will be sync refresh.
I would prefer to have a CPU peak for a while, but server availability, than stressed admin and users manually reconfiguring they device (APPLE I believe should create new profile).
May be this can be done in 8.5.4 Traveler?

Clustering and failover
The IBM® Lotus Notes® Traveler server task itself cannot be clustered to support a high-availability environment. The Lotus Notes Traveler service does recognize that a user's remote mail file is clustered or has additional replicas defined otherwise, and it switches over to synchronize mail from alternate replicas if the user's primary mail server is down.
It is possible to set up multiple Lotus Notes Traveler servers and each could have the same access to all of a user's mail files on remote servers. If a user's Lotus Notes Traveler server is not responsive, the user can manually reconfigure the device's client settings to point to another Lotus Notes Traveler server. However, with the current architecture, once a device switches to a new server, the synchronization anchors will not match between the server and device, and the protocol will initiate a synchronization refresh, where all of the data on the device is replaced by a fresh copy of the data from your mail database. Internally the Lotus Notes Traveler server is keeping track of each piece of data that is on a device. If a device switches to another server, then this history is lost because these tracking databases are not on the network or shared between Lotus Notes Traveler servers.
