2. MYSQL
• MySQL is an open source relational database management system (RDBMS) based
on Structured Query Language (SQL).
• MySQL runs on virtually all platforms, including Linux, UNIX, and Windows. Although
it can be used in a wide range of applications, MySQL is most often associated with
web-based applications and online publishing and is an important component of
an open source enterprise stack called LAMP. LAMP is a Web development platform
that uses Linux as the operating system, Apache as the Web server, MySQL as the
relational database management system and PHP as the object-oriented scripting
language. (Sometimes Perl or Python is used instead of PHP.)

3. HISTORY
• MySQL was created by a Swedish company, MySQL AB, founded by David
Axmark, Allan Larsson and Michael "Monty" Widenius. Original development
of MySQL by Widenius and Axmark began in 1994.[27] The first version of
MySQL appeared on 23 May 1995. It was initially created for personal usage
from mSQL based on the low-level language ISAM, which the creators
considered too slow and inflexible. They created a new SQL interface, while
keeping the same API as mSQL. By keeping the API consistent with the
mSQL system, many developers were able to use MySQL instead of the
(proprietarily licensed) mSQL antecedent.

4. • MySQL can be built and installed manually from source code, but it is more
commonly installed from a binary package unless special customizations are
required. On most Linux distributions, the package management system can
download and install MySQL with minimal effort, though further configuration
is often required to adjust security and optimization settings.
• Though MySQL began as a low-end alternative to more powerful proprietary
databases, it has gradually evolved to support higher-scale needs as well. It
is still most commonly used in small to medium scale single-server
deployments, either as a component in a LAMP-based web application or as
a standalone database server. Much of MySQL's appeal originates in its
relative simplicity and ease of use, which is enabled by an ecosystem of
open source tools such as phpMyAdmin. In the medium range, MySQL can
be scaled by deploying it on more powerful hardware, such as a multi-
processor server with gigabytes of memory.

5. CERTIFICATION
• The Oracle Certified Professional, MySQL 5.6 Database Administrator
(OCP) Certification proves your ability to install and optimize MySQL Server,
set up replication and security, perform database backups and performance
tuning and protect MySQL databases.
•
• MySQL 5.6 delivers superior performance monitoring & diagnostics using
PERFORMANCE_SCHEMA, replication enhancements including support for
multi-threaded replications, new NoSQL interface and partitioning
improvements to support scalability and security enhancements.

6. • MySQL Application Database Administrator – Certification Exam
• The MySQL application database administrator exam now requires
knowledge across a very broad set of areas. The certification path has
been streamlined, requiring only a single exam to become certified, or
to upgrade from a prior release. This more technical exam focuses on
practitioner-level skills. It covers a broader set of topics and deep
dives into key topics such as security, backup, replication and
optimization. Successfully passing this exam gives you an advantage
over your peers working on MySQL 5.6. Up-to-date training and field
experience are recommended.

7. EXAM PREPARATION
• Complete Recommended Training
• Complete the training below to prepare for your exam (optional):
• MySQL for Database Administrators
• Additional Preparation and Information
• A combination of Oracle training and hands-on experience (attained
via labs and/or field experience) provides the best preparation for
passing the exam.
• MySQL 5.6 Reference Manual

8. MySQL Architecture
• Use MySQL client programs to interface with the MySQL Server
interactively and in batch
• Describe how MySQL uses disk and memory resources
• List and describe key characteristics of standard MySQL storage
engines including InnoDB, NDB, MyISAM, MEMORY, FEDERATED
MySQL Server Installation, Configuration and Maintenance

packages for Windows and Linux platforms
• Configure MySQL Server deployments using options files, command-
line options and server variables.
• Identify, configure, locate and describe appropriate use cases for
MySQL the error, binary, general query and slow query log.

9. • MySQL Security
• Describe appropriate steps to secure a MySQL deployment at the
operating system, filesystem and network levels.
• Create and maintain user accounts with appropriate privileges and
configuration.
• Deploy and configure MySQL Enterprise Audit
• Diagnostic Data and Metadata Sources in MySQL

and diagnose performance problems.
• Obtain MySQL metadata from INFORMATION_SCHEMA tables

10. Optimizing MySQL Performance
• Demonstrate ability to diagnose and optimize poorly-performing
queries.
• Tune MySQL Server configuration for best performance.
• Apply best practices in optimizing schema objects
• Demonstrate understanding of locking concepts as applied to MySQL
Server and storage engines.
• Create and utilize table PARTITIONING
Backups and Recovery in MySQL
• Create and restore logical backups using mysqldump
• Create and restore binary backups
• Use backups for data recovery

11. • High Availability Techniques for MySQL
• Describe, configure, deploy and troubleshoot MySQL replication
• Describe and contrast characteristics of common MySQL high
availability solutions (MySQL Cluster, DRBD, Windows Failover
Clustering, Solaris Cluster, OVM Template for MySQL Enterprise)

15. AFTER THE EXAM
• Within 30 minutes of completing your Oracle Certification exam, you will
receive an email from Oracle notifying you that your exam results are
available in CertView. If you have previously authenticated your CertView
account, simply login and select the option to "See My New Exam Result
Now."
• If you have not authenticated your CertView account yet at this point, you
will need to proceed with your account authentication.
• Authentication requires an Oracle Single Sign On username and password
and the following information from your Pearson VUE profile: email address
and Oracle Testing ID. You will be taken to CertView to log in once your
account has been authenticated.
