MySQL 5.5 Reference Manual Including MySQL NDB Cluster 7.2 Reference Guide

18.3.3.12 SCI Transport Connections in NDB Cluster

[sci] sections in the config.ini file explicitly define SCI (Scalable Coherent Interface) connections between cluster nodes. Using SCI transporters in NDB Cluster requires specialized hardware as well as specially-built MySQL binaries; compiling such binaries is not supported using an NDB 7.2 or later distribution.

Restart types.  Information about the restart types used by the parameter descriptions in this section is shown in the following table:

Table 18.269 NDB Cluster restart types

Symbol Restart Type Description
N Node The parameter can be updated using a rolling restart (see Section 18.5.5, “Performing a Rolling Restart of an NDB Cluster”)
S System All cluster nodes must be shut down completely, then restarted, to effect a change in this parameter
I Initial Data nodes must be restarted using the --initial option

The following parameters are present in NDB source code as well as the output of ndb_config and other NDB programs, but are nonfunctional in NDB 7.2 and later.
