Answer 1

Make sure your NodeManager uses the same setting as you set in the AdminServer. I set my NodeManager to use plain socket in the AdminServer but the actual NodeManager started in secured socket by default. Check you NodeManager log to confirm. For example, this is in my log

<Nov 3, 2016 9:22:45 PM EDT> <INFO> <Secure socket listener started on port 5556, host /192.168.2.3>

and I got the unreachable error. After I changed the parameter SecureListener=false in nodemanager.properties, I could start the server just fine.

Answer 2

I was facing this issues. After trying several methods, I realised that I was not running Node Manager service.

For starting Node Manager service, you need to go to

1. C:\Oracle\Middleware\Oracle_Home\user_projects\domains\base_domain\bin\startNodeManager.cmd (Specific to my PC)

2. Run with admin privileges.

It solved my problem.
