My UIM platform is currently deployed and operates from the two Data-centre's. However, a project is under way to set-up high availability which was see one Data-Centre being the primary and the other becoming secondary.
The estate consist of 4500/5000 robots and 35 Hub Servers.
How do you set-up and configure Multiple UIM Discovery Servers in a High-Availability set-up, please? What HA methods are available(hot warm cold) standby set-ups?
this would depend on how you are doing HA to some extent.
If you are using MS active passive cluster for primary then this cluster would take care of the discovery HA as well as the discovery server is on the primary.
If you are using the UIM HA probe setting up the discovery_sever on your HA hub and leaving it deactivated when not in use and then activating it with the HA during Fail-over should accomplish your needs as well.
With discovery_server 8.5 if you have any LUA scripts setup or manual excludes you would need to move these manually if using UIM with the HA probe.
Hope this helps.
