Objective: Setup High Availability for the Live Maps Portal.
This setup will work for Live Maps Version 10.0 and above. If you are currently on an earlier version of Live Maps, then you will need to upgrade first.
A common request is for Live Maps to be setup for High Availability. This is typically setup by installing two or more Live Maps Portals. Also using a common URL that is processed through a Load Balancer of some type, like an F5.
Above is the basic setup. Here are the rules of the road.
- Setup two or more Live Maps Portals. These can be setup with Forms or Windows authentication.
- Sticky sessions (Affinity) should be setup when connecting to a portal on a set server. Meaning once you authenticate with one server, you need to stay on that server until the session is over.
- Each Live Maps server should point to a specific SCOM server. Now Live Maps can be installed on a SCOM server, and if that is the case it should point to itself.
- On this same note – it could be possible to point this to a resource pool for SCOM, but only if you can make sure that once a user has authenticated with one particular SCOM server, they stay on that server and do not try to switch between several SCOM servers.
- On that same note part 2 – If you do try to use connect to a resource pool and you are using Windows Authentication, you need to make sure that each Live Maps server can authenticate to each SCOM server.
- Generally we recommend that it targets a set SCOM server or is installed on a SCOM server.
- On each server, go into the IIS Manager, and then navigate to the Live Maps portal website (or child application). From there, double click on Application Settings. Be sure that the following settings are added or set.
- Janus:DefaultManagementServer – Setting should be set to your SCOM server that the portal is targeting.
- Janus:AlwaysUseDefaultServer – true
One last thing on this. If you are setting up Forms Authentication, then there should not be any issues. In fact it may be a good idea to test the setup with Forms first. If you are setting it up with Windows Authentication AND Live Maps is on a separate server other than a SCOM server, you may run into authentication issues. This is especially true with using a different URL other than the server name. In those cases it will be helpful to use this KB article to troubleshoot. https://savision.com/knowledge-base/troubleshooting/live-maps-portal-windows-authentication-troubleshooting/
