ADMU0111E: NullPointerException adding a node to DeploymentManager cell
 Technote (troubleshooting)
 
Problem(Abstract)
During addnode operation, addnode fails with NullPointerException if there is no server defined on the node.
 
Cause
By default, the server1 application server will be created during the installation process. If server1 is not required in the configuration, then it should be removed only after adding the node to the DMGR cell. Otherwise, the addnode will fail with the exception shown below. If there is another server, in addition to server1 on the node, server1 can be removed prior to federation.

Diagnosing the problem
At least one server is required to add a node to DeploymentManager cell.
 
Resolving the problem
If there is no other server available on the node, follow the steps below to recreate the server on the node, and then run the addNode command.
  1. Connect to base node wsadmin using conntype NONE
    wsadmin -conntype NONE

  2. set node [$AdminConfig getid /Node:mynode/]

  3. $AdminConfig create Server $node {{name myserv} {outputStreamRedirect {{fileName myfile.out}}}}

  4. $AdminConfig save
