Detailed Description

Cluster Configuration (corresponds to initial configuration file).

Contains all cluster configuration parameters.

The information includes all configurable parameters for a NDB cluster:

  • DB, API and MGM nodes with all their properties,
  • Connections between nodes and computers the nodes will execute on.

The following categories (sections) of configuration parameters exists:

  • COMPUTER, DB, MGM, API, TCP, SCI, SHM, OSE
