MariaDB Database Administration

This MariaDB Database Administration course is designed for MariaDB 10 Database Administrators who have a basic understanding of a MariaDB database and a good working knowledge of SQL commands.

The course provides an understanding of MariaDB Architecture and practical experience in setting up, configuring and maintaining a MariaDB server, and backing up and recovering data. This MariaDB Database Administration course also covers MySQL replication and its role in high availability and scalability.

Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.

Versions supported 10.4, 10.3, 10.2 and 10.1.

The delegate will learn and acquire skills as follows:

• Using Client Programs for MariaDB DBA work
• Using GUI Tools
• Obtaining metadata
• Configuring the Server
• Install and configure the MariaDB Server and client programs
• Administer and tune a server
• Upgrading a Running Server

Database Administrators, Database Developers and Technical Consultants who need to setup, administer, monitor and support MariaDB databases and servers.

At the end of the MariaDB Database Administration course, delegates will have the knowledge to use all the features available to administer, monitor and support MariaDB databases and servers.

A working knowledge of MariaDB is required. Delegates should have knowledge of relational database concepts; have knowledge of MySQL data types; be able run Queries using SQL; join tables and run basic DDL and DML statements. This can be gained by attendance on the Introduction to MariaDBcourse.

This course is run on a Linux operating system, a basic knowledge of Linux/UNIX is essential. This knowledge can be gained by attendance the Linux Introduction course.
