TM1 High Availability or Load Balancing

Just a quick post on what I know about configuring High Availability (HA) or Load Balancing for TM1 at the moment. Copying this link will save me some keystrokes along the way ;)

TM1 Web and Applications server can be fully load-balanced / HA if configured as per (from 10.2 upwards) using this IBM Guide.

TM1 Admin server and TM1 server itself cannot be load-balanced or configured for HA, there will have to be some downtime / lost connections if one of the servers goes down.

The usual configurations for TM1 Server ‘high availability’ / fast restore are (2 TM1 servers, A & B):

Overall, TM1 is not an OLTP / line-of-business system and users are quite tolerant for down-time of a few minutes / hours, so I’d rather not go the hard yards to set it up unless it’s really vital.
