MySQL Cluster Manager 8.0.42 User Manual
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.
