I've upgraded from vCenter 5.5U2 to vCenter6. Everything works (including the Windows Client), but in the Web Client I get the message "empty inventory" when clicking on various tabs (datastores, hosts, vcenters, networking etc).
If I click on Inventory Lists I can find most elements. If I click on a datastore there, I can see the VMs running on that datastore etc.
I also see tasks going on in vCenter (migrations etc). I have checked permissions, and all seems OK. I have tried both domain and "SSO" (firstname.lastname@example.org) logins, and the problem is the same.
I did the upgrade "offline", where vCenter only had access to the domain controller, in case of a upgrade failure the hosts agent would not be upgraded. All seemed good, so I let that happen. But then I noticed this problem after starting up vCenter connected to the network.
Any idea what could be the problem?
Works now. I increased Inventory Service Java Heap size in "C:\Program Files\VMware\vCenter Server\invsvc\wrapper\conf\wrapper.conf".
I found no wrapper.java.maxmemory line, so I added it (guessed it would work after reading some equal lines in older versions).
I have restarted several times before this without any luck, so I think this was the thing fixing the problem.
I set the max to 2048
I tried changing this in the config-file in this folder first, but that did not help.
