I have two machines: A, B I want to create a weblogic cluster and I have installed software, and node manager.
I don´t understand what is exactly the purpose of nmenroll. Please can you explain it for me?. I have created a cluster in machine A , and export the structure into machine B, and everything is correct, for what I need nmenroll?
"nmEnroll" is required to register your weblogic domain with the nodemanager running on that machine, so that nodemanager can monitor resources associated with the enrolled domain.
In your case suppose you have 2 managed servers each on domain A & B and all on same machine M1. Now you start a nodemanager on machine M1 and enroll domain A & B with nodemanager on M1. Post that you can configure managed server on both domain to be monitored by nodemanager, so nodemanager will start/stop that server, auto-restart on failure, perform a crash recovery, etc.
