NodeId  is the preferred parameter name to use when identifying management nodes. Although the older Id  continues to be supported for backward compatibility, it is now deprecated and generates a warning when used; it is also subject to removal in a future NDB Cluster release. 

• ExecuteOnComputer

This refers to the Id  set for one of the computers defined in a [computer]  section of the config.ini file.

• PortNumber 

## Important 

This parameter is deprecated, and is subject to removal in a future release. Use the HostName  parameter instead.

This is the port number on which the management server listens for configuration requests and management commands. 

• 

The node ID for this node can be given out only to connections that explicitly request it. A management server that requests “any”  node ID cannot use this one. This parameter can be used when running multiple management servers on the same host, and HostName  is not sufficient for distinguishing among processes. Intended for use in testing. 

• HostName

Specifying this parameter defines the hostname of the computer on which the management node is to reside. To specify a hostname other than localhost , either this parameter or ExecuteOnComputer  is required.
