MySQL Cluster Manager 8.4 Release Notes
Abstract
This is the User Manual for the MySQL
Cluster Manager, version 8.4.6. It documents
the MySQL Cluster Manager Agent and
MySQL Cluster Manager Client software
applications, which can be used to administer
MySQL NDB Cluster, a version of the
MySQL Database System
(referred to hereafter as “MySQL Server” or simply
“MySQL”) that incorporates the
NDB storage engine for high
availability and data redundancy in a distributed computing
environment.
This manual applies to MySQL Cluster Manager 8.4.6 and contains information that may not apply to older versions of the MySQL Cluster Manager software. For documentation covering previous MySQL Cluster Manager releases, see MySQL Documentation: MySQL NDB Cluster, on the MySQL website.
MySQL Cluster Manager features. This manual describes features that may not be included in every version of MySQL Cluster Manager, and such features may not be included in the version of MySQL Cluster Manager licensed to you. If you have any questions about the features included in your version of MySQL Cluster Manager, refer to your MySQL Cluster Manager license agreement or contact your Oracle sales representative.
MySQL Cluster Manager, MySQL Server, and MySQL NDB Cluster features. This manual contains certain basic information about MySQL Server and MySQL NDB Cluster; however, it is not in any way intended as an exhaustive reference for either of these products.
MySQL Cluster Manager 8.4 supports MySQL NDB Cluster 8.4, MySQL NDB Cluster 8.0, and MySQL NDB Cluster 7.6.
MySQL NDB Cluster functionality varies between MySQL NDB Cluster releases; MySQL Cluster Manager cannot supply or emulate MySQL NDB Cluster features that are not present in the version of the MySQL NDB Cluster software in use.
For complete information about MySQL Server and MySQL NDB Cluster see MySQL NDB Cluster 8.4, MySQL NDB Cluster 8.0, or MySQL NDB Cluster 7.5 and NDB Cluster 7.6.
If you do not have the MySQL Server and MySQL NDB Cluster documentation, you can obtain it free of charge from the MySQL Documentation Library, on the MySQL website.
