21.3.3.4 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

    Version (or later) NDB 7.5.0
    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

    Version (or later) NDB 7.5.0
    Type or units name or IP address
    Default [none]
    Range ...
    Restart Type N

    This is the computer's hostname or IP address.

Restart types.  Information about the restart types used by the parameter descriptions in this section is shown in the following table:

Table 21.7 NDB Cluster restart types

Symbol Restart Type Description
