MySQL 5.6 Reference Manual Including MySQL NDB Cluster 7.3-7.4 Reference Guide
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 18.3.3.9, “NDB Cluster TCP/IP Connections”, or
Section 18.3.3.11, “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.
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.
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.
