Our customer wants us to implement Clustering with High Availability in Clarity.
Earlier, we had implemented High Availability using OS Level Active-Passive Cluster, so that if one server goes down for some reason, the other one takes over. The document store mount point gets attached to the active server automaticaly.
However, it does not switch over to the other server, if for some reason the clarity app service goes down on one server (as the OS of the server still reports it as active server). What do we need to do to achieve High Availability of application and not OS. Also, the customer wants to have both servers in active active configuration. Are both the requirements achievable at the same time? If yes, how will the two servers access document store at the same time?
