NDB Cluster Configuration Files S (NDB 8.0.13) Restart Type This refers to the  Id  set for one of the computers (hosts) defined in a  [computer]  section of the configuration file. This parameter is deprecated, and is subject to removal in a future release. Use the  HostName  parameter instead. The node ID for this node can be given out only to connections that explicitly request it. A management server that requests “any”  node ID cannot use this one. This parameter can be used when running multiple management servers on the same host, and  HostName  is not sufficient for distinguishing among processes. Intended for use in testing. • Important Version (or later) NDB 8.0.13 Type or units name or IP address Default [...] Range ... Restart Type N (NDB 8.0.13) Specifying this parameter defines the hostname of the computer on which the SQL node (API node) is to reside. To specify a hostname, either this parameter or  ExecuteOnComputer  is required. If no  HostName  or  ExecuteOnComputer  is specified in a given  [mysql]  or  [api]  section of the config.ini  file, then an SQL or API node may connect using the corresponding “slot”  from any host which can establish a network connection to the management server host machine.  This differs from the default behavior for data nodes, where  localhost  is assumed for  HostName  unless otherwise specified . • LocationDomainId • HostName Version (or later) NDB 8.0.13 Type or units integer Default 0 Range 0 - 16 Restart Type S (NDB 8.0.13) Assigns an SQL or other API node to a specific availability domain (also known as an availability zone) within a cloud. By informing  NDB  which nodes are in which availability domains, performance can be improved in a cloud environment in the following ways: •If requested data is not found on the same node, reads can be directed to another node in the same availability domain. •Communication between nodes in different availability domains are guaranteed to use  NDB transporters’ WAN support without any further manual intervention. 4153
