HostName: Host name or IP address of this computer.

Id: Unique identifier for this computer.

AllowUnresolvedHostNames: When false (default), failure by management node to resolve host name results in fatal error; when true, unresolved host names are reported as warnings only.

Checksum: If checksum is enabled, all signals between nodes are checked for errors.

Group: Used for group proximity; smaller value is interpreted as being closer.

HostName1: Name or IP address of first of two computers joined by TCP connection.

HostName2: Name or IP address of second of two computers joined by TCP connection.

NodeId1: ID of node (data node, API node, or management node) on one side of connection.

NodeId2: ID of node (data node, API node, or management node) on one side of connection.

NodeIdServer: Set server side of TCP connection.

OverloadLimit: When more than this many unsent bytes are in send buffer, connection is considered overloaded.

PreferIPVersion: Indicate DNS resolver preference for IP version 4 or 6.

PreSendChecksum: If this parameter and Checksum are both enabled, perform pre-send checksum checks, and check all TCP signals between nodes for errors.

Proxy: ....

ReceiveBufferMemory: Bytes of buffer for signals received by this node.

SendBufferMemory: Bytes of TCP buffer for signals sent from this node.

SendSignalId: Sends ID in each signal. Used in trace files. Defaults to true in debug builds.

TcpSpinTime: Time to spin before going to sleep when receiving.

TCP_MAXSEG_SIZE: Value used for TCP_MAXSEG.

TCP_RCV_BUF_SIZE: Value used for SO_RCVBUF.

TCP_SND_BUF_SIZE: Value used for SO_SNDBUF.

TcpBind_INADDR_ANY: Bind InAddrAny instead of host name for server part of connection.

Checksum: If checksum is enabled, all signals between nodes are checked for errors.

Group: Used for group proximity; smaller value is interpreted as being closer.

HostName1: Name or IP address of first of two computers joined by SHM connection.

HostName2: Name or IP address of second of two computers joined by SHM connection.

NodeId1: ID of node (data node, API node, or management node) on one side of connection.

NodeId2: ID of node (data node, API node, or management node) on one side of connection.

NodeIdServer: Set server side of SHM connection.

OverloadLimit: When more than this many unsent bytes are in send buffer, connection is considered overloaded.

PreSendChecksum: If this parameter and Checksum are both enabled, perform pre-send checksum checks, and check all SHM signals between nodes for errors.

SendBufferMemory: Bytes in shared memory buffer for signals sent from this node.

SendSignalId: Sends ID in each signal. Used in trace files.

ShmKey: Shared memory key; when set to 1, this is calculated by NDB.

ShmSpinTime: When receiving, number of microseconds to spin before sleeping.

ShmSize: Size of shared memory segment.

Signum: Signal number to be used for signalling.
