22.3.3.8 Defining the System

The [system] section is used for parameters applying to the cluster as a whole. The Name system parameter is used with MySQL Enterprise Monitor; ConfigGenerationNumber and PrimaryMGMNode are not used in production environments. Except when using NDB Cluster with MySQL Enterprise Monitor, is not necessary to have a [system] section in the config.ini file.

More information about these parameters can be found in the following list:

• ConfigGenerationNumber

  Table 22.209 This table provides type and value information for the ConfigGenerationNumber system configuration parameter

  Property	Value
  Version (or later)	NDB 8.0.13
  Type or units	unsigned
  Default	0
  Range	0 - 4294967039 (0xFFFFFEFF)
  Restart Type	N

  
  

  Configuration generation number. This parameter is currently unused.

  Property	Value

  Set a name for the cluster. This parameter is required for deployments with MySQL Enterprise Monitor; it is otherwise unused.

  You can obtain the value of this parameter by checking the Ndb_system_name status variable. In NDB API applications, you can also retrieve it using get_system_name().

  Property	Value
