Chapter 2 What Is New in MySQL Cluster Manager 8.4

MySQL Cluster Manager 8.4 marks the start of a new series of LTS (Long Term Support) releases. MySQL Cluster Manager 8.4 is recommended for use on production systems.

The 8.4.X LTS releases will focus on security and bug fixes while the next Innovation series will include new features.

Here is a summary of the major changes for MySQL Cluster Manager going from series 8.0 to series 8.4:

• MySQL Cluster Manager now supports TLS Link Encryption for NDB Cluster. See Section 4.11, “Using TLS Connections for NDB Clusters” for details.

• Encrypted connections for agents and clients are now supported by MySQL Cluster Manager. See Section 4.10, “Using Encrypted Connections for MySQL Cluster Manager Agents and Clients” for details.

• The /etc/init.d/mcmd script has been removed from delivery packages for the Solaris platform.

• The --background option for the mcm client commands have been removed.

• The command-line format of the following options has been deprecated since release 8.0.30, and it can no longer be used now:

  • --bind-port

  • --copy-port

  • --xcom-port

  • --mcmd-user

  Use the --mcmd.[option] format instead, or specify the options in the configuration file.

• The show status command can now be used without any options, in which case the runtime information of the mcmd agent the client connected to is returned.
