# High Availability Identity Management Install (10gAS)

The installation guides tell you that you must have your load balancer resolve via dns or in the host file. The guides don't mention that if you have a metadata repository on a separate box, then the load balancer must resolve from that box as well. If it doesn't, you will get the following error in InstallActions.log:
