The listings in this section provide information about
parameters used in the [computer],
[tcp], and [shm] sections
of a config.ini file for configuring NDB
Cluster. For detailed descriptions and additional information
about individual parameters, see
Section 4.3.9, “NDB Cluster TCP/IP Connections”, or
Section 4.3.11, “NDB Cluster Shared-Memory Connections”, as appropriate.
The following parameters apply to the
config.ini file's
[computer] section:
The following parameters apply to the
config.ini file's
[tcp] section:
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.PortNumber: Port used for TCP transporter.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.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.
The following parameters apply to the
config.ini file's
[shm] section:
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.PortNumber: Port used for SHM transporter.SendSignalId: Sends ID in each signal. Used in trace files.ShmKey: Shared memory key; when set to 1, this is calculated by NDB.ShmSize: Size of shared memory segment.Signum: Signal number to be used for signalling.
