18.3.3.4 Defining Computers in an NDB Cluster

The [computer] section has no real significance other than serving as a way to avoid the need of defining host names for each node in the system. All parameters mentioned here are required.

• Id

  Table 18.6 This table provides type and value information for the Id computer configuration parameter

  Property	Value
  Version (or later)	NDB 7.3.1
  Type or units	string
  Default	[none]
  Range	...
  Restart Type	IS

  
  

  This is a unique identifier, used to refer to the host computer elsewhere in the configuration file.

  Important

  The computer ID is not the same as the node ID used for a management, API, or data node. Unlike the case with node IDs, you cannot use NodeId in place of Id in the [computer] section of the config.ini file.

• HostName

  Table 18.7 This table provides type and value information for the HostName computer configuration parameter

  Property	Value
  Version (or later)	NDB 7.3.1
  Type or units	name or IP address
  Default	[none]
  Range	...
  Restart Type	N

  
  

  This is the computer's hostname or IP address.
