课程名称：Oracle DBA（数据库管理）认证培训 课程概述：欢迎参加由Uplatz提供的Oracle DBA课程。本课程主要讲解Oracle数据库的安装、配置、管理及性能调优，旨在实现Oracle数据库的高效能、完全控制与数据完整性，包括存储、安全性、备份与恢复机制。Oracle数据库管理员（DBA）主要负责数据库管理。在云数据库日益普及的背景下，DBA的角色在行业中变得愈发重要，并且此职位的薪资也相对较高。 本课程深入涵盖Oracle数据库管理的各个方面，从数据库架构到存储结构的管理、用户管理、锁定与审计等概念，再到备份与恢复机制的详细探讨。此外，课程还介绍Oracle数据库迁移到云基础设施的步骤。学员将专注于日常数据库管理所需的技能和最佳实践，包括安全性、用户创建与管理、空间管理、撤消与重做的管理、运行工具、配置Oracle网络以及备份和恢复技术。 课程内容包括Oracle 12c数据库架构的深入讨论，学员将学习如何安装和维护Oracle Database 11g，并理解Oracle数据库架构及其各组件的互动关系。学员还将掌握创建操作性数据库、有效管理各种结构的方法，包括性能监控、数据库安全、用户管理以及备份/恢复技术。 课程大纲涵盖了Oracle数据库管理的各项主题，包括SGA实例管理、文件与表空间管理、用户管理与安全、表与索引管理等。通过练习，学员将获得第一手经验，掌握通过Oracle OCP考试所需的关键DBA概念。 学员将学习成功安装和配置一个Oracle数据库，创建表空间和文件，管理安全和用户访问，创建表、索引组织的表、聚集表、索引、位图索引、基于函数的索引和位图连接索引等。 Oracle DBA课程大纲包括： - 架构 - DBCA - 实例 - 用户 - 表空间与存储 - 临时表空间 - 撤消 - 闪回技术 - Oracle网络环境 - Oracle锁定 - Oracle审计 - EM和数据泵 - 用户管理备份 - 用户管理恢复 - RMAN备份 - RMAN恢复 - Oracle数据库迁移到云 一些基本术语包括： - 实例：用于从数据库检索数据的后台进程和内存结构。 - 进程：运行中的实例，可以是Oracle进程或用户进程。 - 缓冲区缓存：SGA组件，用于存储最近或频繁使用的数据，提升性能。 - 共享池：用于捕获与用户共享的信息，如存储过程和SQL语句等。 - 撤消日志缓冲区：保持数据库更改记录，有助于在系统失败时恢复数据库。 本课程将为学员提供全面的Oracle数据库管理知识与实践经验，非常适合希望深入了解Oracle DBA领域的学习者。
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.Oracle DBA course curriculumArchitectureDBCAInstanceUsersTablespace and StorageTemporaray TablespaceUndoFlashback TechnologyOracle Networking EnvironmentOracle LockingOracle AuditingEM and Data PumpUser Managed BackupUser Managed RecoveryRMAN - BackupRMAN - RecoveryOracle Database Migration to CloudBasic 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.
