Overview/Description
Because there is a finite amount of memory available on a database server and on an Oracle Database 11g instance, you must pay attention to how memory is allocated. Also, database planning must include a balance between performance, cost, and reliability. You must consider the investment in the system architecture, which includes the hardware and software infrastructure needed to meet your requirements. This course explores the database's memory structures, focusing on how to configure SGA parameters and how to implement Automatic Memory Management and Automatic Shared...
Overview/Description
By using the Database Resource Manager, you have more control over the allocation of machine resources than is normally possible through operating system resource management alone. Many tasks in the Oracle environment need job-scheduling capabilities. Using advanced Scheduler features, you can exercise more control over various aspects of scheduling, such as job windows and prioritizing jobs. This course explains how to configure the Database Resource Manager to access and create resource plans, create, configure, and administer consumer groups, as well as activate a...
Overview/Description
To effectively manage space, you can configure automatic management by the Oracle database server. This allows you to generate alerts about potential problems and recommend possible solutions. This course explores how to use the Oracle database server for automatic space management, proactively monitor and manage tablespace space usage, and reclaim wasted space from tables and indexes by using the segment shrink functionality. Using the segment advisor, resumable space allocation, and moving tablespaces are also covered. This course will also explore how to duplicate a...
Overview/Description
From time to time Oracle DBAs are required to move data. Oracle Database 11g Release 2 offers various ways to complete this task, including Oracle Data Pump, SQL*Loader, and the use of external tables. DBAs are also required to ensure that the database is up-to-date with the latest patches and that critical errors are resolved, which includes contacting Oracle for support. This course explores how to move data using Data Pump Wizards or the command line. Working with the Enterprise Manager Support Workbench, My Oracle Support, service requests, and patch management are...
Overview/Description
As a database administrator it is very important to understand how to restore and recover your database in the event of a loss of a file due to media, hardware, or user error. The restoration process involves moving a backup into place to be used by the database when a file is damaged. The recovery process involves applying redo to bring the file forward in time to before the failure or up to the failure point. This course discusses the type of failures that can occur and how to recover from them. It also discusses how to perform user-managed backup and recoveries. This...
Overview/Description
An Oracle database is divided into logical storage units called tablespaces. Oracle also provides Oracle-Managed Files (OMF), which eliminate the need for the DBA to directly manage the operating system files in the Oracle database. To access the database, a user must specify a valid database user account and successfully authenticate as required by that user account. What the user can execute once they are logged in is controlled by privileges granted to them, which can be system or object. Privileges can be better controlled by using roles and profiles, which control...
Overview/Description
Oracle Database 11g Release 2 offers Automatic Storage Management (ASM), which eliminates the need for many tasks that are required on a non-ASM storage environment by the DBA. Some of these tasks include I/O performance tuning, file system, cluster file system, and raw device management, and data file movements and reorganizations. When ASM is used, an ASM instance is also used. The ASM instance allocates memory and uses the SGA differently than in a database instance. This course describes the ASM instance and how it works, and demonstrates how to manage it with various...
Overview/Description
RMAN uses a recovery catalog to store metadata about Oracle databases, and allows stored scripts to be used to run sequences of RMAN commands stored in the catalog. When administering an Oracle Database, it is important to be familiar with what a backup is, how the process of creating a backup is completed, and the various types of backups available. This knowledge allows you to make an informed decision on the best way to maintain the integrity of your data and the availability of your database. This course discusses how to create and manage the recovery catalog. It also...
Overview/Description
Reconstructing the contents of all or part of a database from a backup typically involves two phases. The first phase is the retrieval of a copy of the data file from the backups. The second involves reapplying changes to the file that occurred since the backup, using archived and online redo logs. To effectively administer an Oracle Database 11g database, recovery should be performed when critical or non-critical files are lost. Once you configure RMAN to perform recovery operations, it is important to have measures in place to monitor RMAN jobs. This course explains how...
