Oracle DBA (Database Administration) Certification Training

Description

A warm welcome to the Oracle DBA course by Uplatz.

Oracle Database Administration is defined as the installation, configuration, management, administration, and performance tuning of Oracle database to achieve high performance from an Oracle database with complete access control and data integrity, storage, safety, backup, and recovery mechanisms.

An Oracle Database Administrator (DBA) is primarily responsible and accountable for performing database administration. With massive cloud-based database computing, database services, high performance and reliability requirements, data integration, transformation, storage, etc., as well as with complex and huge applications both in-premise and cloud-based, the role of Oracle DBAs has assumed significant importance in today's industry scenario and hence a DBA gets highly paid and are always in demand.

Uplatz provides in-depth training on Oracle Database Administration with focus on teaching DBA concepts in depth starting from Oracle database architecture and installation/configuration/management of database storage structure to user management, concepts such as locking and auditing, and deep dive into backup and recovery mechanisms.

This Oracle DBA course also covers the steps involved in Oracle database migration to cloud-based infrastructure.

In this Oracle DBA training, you will concentrate on the skills and best practices required for day-to-day database administration tasks such as security, creating and managing users, space management, administering undo and redo, running utilities, configuring Oracle networking, and all backup and recovery techniques.  An in-depth discussion of Oracle 12c database architecture is also provided.

The students will learn how to install and maintain Oracle Database 11g and gain a conceptual understanding of the Oracle database architecture and how its components work and interact with one another. You will also understand how to create an operational database and properly manage the various structures in an effective and efficient manner including performance monitoring, database security, user management, and backup/recovery techniques.

Broad in scope, this course covers all of the Oracle Database Administration topics including SGA instance management, file & tablespace management, user administration & security and table & index management. Exercises are used to demonstrate each feature and the students will gain first-hand experience in the key Oracle DBA concepts required to pass the Oracle OCP exam.

The student will learn how to successfully install and configure a working Oracle database, create tablespaces and files, manage security and user access, and create tables, index-organized tables, cluster tables, indexes, bitmap indexes, function-based indexes and bitmap join indexes.

Basic terminologies involved in Oracle Database Administration are:

• Instance - It is defined as the background processes and memory structure used to retrieve data from a database.

• Process - Also termed as task or job, is a running instance. There are two types of processes in Oracle database system namely, Oracle processes and User processes. There is no need to use an operating system command to interact with the database.

• Buffer Cache - It is an SGA component that acts as a buffer to store the data being customized or queried. It stores the most recently or frequently used data in memory which improves the performance. All the user processes that are connected to the database share access to it.

• Shared pool - It captures information to be shared with users. For example, stored procedures, SQL statements, etc can be cached for reusability and fast access.

• Redo Log Buffer - It maintains a log of changes that are made in the database. The redo log files run in a circular motion and get overwritten. So, to maintain the recoverability of the database for a longer duration, they are archived into archive logs. Therefore, the redo log helps to recover an instance when there is a system failure. This improves the performance and functioning of the database system.

• Large pool - It is the optional area that offers memory allocations for large processes, like recovery operations and Oracle backup.

• Locks - For controlling the simultaneous access to data resources, locks are used.

The database consists of logical and physical structures. Because these structures are separate, the management of the physical storage of data does not affect the access to logical structures.
