Ops Center Gurus, I recently installed 12c to test in parallel with our 11gR3 installation.
Installation and proxy configuration was clean. I unmanaged a system in the 11g setup, and did /var/scn/install/uninstall -a to remove the 11g proxy software as well as removing the /var/opt/sun/xvm directory structure to avoid persistence issues.
This system is on the same subnet as the EC. The first 3 octets of the IPs are the same as well as the subnet mask.
I wotk through the BUI to find this asset, and it discovers and verifies 4 service tags. When I tell it to manage the asset, I can see it copy the agent bundle and install it. However when it tries to configure, I get the message:
AgentProvConfigure - Unable to find a proxy controller network interface that can be reached from agent IP Address /###.###.###.124 (80273) (IP hidden for security)
If I run agentadm configure -x <IP of EC>... it configures properly and shows up as a managed asset.
Do I need to configure anything in the Networks section of the navigation pane?
I know I haven't provided a lot of information, but I was wondering if anyone has seen/overcome this problem before.
As strange as this sounds, I've found that if I choose the option to manage the client without an agent, it works. Then I go into the OS asset in the asset tab, and in the actions menu, there is an option to Switch Management Access. This then goes out and install and successfully configures the agent. I guess somehow setting up the SSH stream of information magically allows it to see the proxy interface it couldn't before.
Thanks, tried as suggested and it worked for me. I was however not able to do a manual installation of the agent software but had to go through the EC with these two steps. First agentless, then enabling the agent.
I lodged a ticket with oracle support about this and they finally came back saying it's a bug (7200811) and that a workaround is to edit /var/opt/sun/xvm/persistence/scn-proxy/allowInterfaces on each on your proxy and add a list of proxy IP addresses, one per line. This did fix the issue for me.
