Database Resource Manager Self-Managing Database Oracle Database provides a high degree of self-management by automating routine DBA tasks and reducing complexity of space, memory, and resource administration.
Oracle Database self-managing features include the following: Automatic Maintenance Tasks Oracle Database automatically schedules periodic maintenance tasks such as statistics collection and space recovery. These tasks run in a set of Oracle Scheduler windows known as maintenance windows.
Oracle Enterprise Manager Oracle Enterprise Manager is a system management tool that provides central management of your database environment.
Combining a graphical console, Oracle Management Servers, Oracle Intelligent Agents, common services, and administrative tools, Oracle Enterprise Manager provides a comprehensive systems management platform for managing Oracle products.
From the client interface, the Oracle Enterprise Manager Console, you can perform the following tasks: Once connected, you can perform operations on objects in the database. You designate only the total memory size to be used by the instance, and Oracle Database dynamically exchanges memory between the SGA and the instance PGA as needed to meet processing demands.
This capability is referred to as automatic memory management. In this memory management mode, the database also dynamically tunes the sizes of the individual SGA components and the sizes of the individual PGAs. Database files are automatically distributed across all available disks, and database storage is rebalanced automatically whenever the storage configuration changes.
Automatic Storage Management also provides redundancy through the mirroring of database files. This improves manageability and diagnosability of network attached storage accessed with NFS. Analysis is performed top down, first identifying symptoms and then refining them to reach the root causes of performance problems.
ADDM also documents non-problem areas of the system.
For example, wait event classes that are not significantly affecting the performance of the system are identified and removed from the tuning consideration at an early stage, saving time and effort that would be spent on items with little or no impact on overall system performance.
In addition to problem diagnostics, ADDM recommends possible solutions. ADDM considers a variety of changes to a system while generating its recommendations, which include hardware changes, database configuration changes, modification of schema objects, modification of applications, and referrals to other advisors.
The output of the SQL Tuning Advisor is in the form of an advice or recommendation, along with a rationale for each recommendation and its expected benefit.
The recommendation relates to collection of statistics on objects, creation of new indexes, restructuring of the SQL statement, or creation of SQL Profile. Users can choose whether or not to accept the recommendation to complete the tuning of the SQL statements.
It can recommend that you create access structures such as indexes and materialized views to optimize SQL queries. It can also recommend that you partition tables, indexes, or materialized views to improve query performance.
You can select your workload from various sources, including current and recent SQL activity, a SQL repository, or a user-defined workload such as from a development environment.
The advisor then recommends changes to improve the performance of the workload as a whole. The Streams Performance Advisor reports performance measurements for a Streams topology, including throughput and latency measurements. The Streams Performance Advisor also identifies bottlenecks in a Streams topology so that they can be corrected.
In addition, the Streams Performance advisor examines the Streams components in a Streams topology and recommends ways to improve their performance. The Scheduler lets database administrators and application developers control when and where various tasks take place in the database environment.
For example, database administrators can schedule and monitor database maintenance jobs such as backups or nightly data warehousing loads and extracts.Reading: Name Server Introduction A name server is a computer hardware or software server that implements a network service for providing responses to queries against a directory service.

STUDY. PLAY. Agile Development. an information systems development process that emphasizes flexibility to anticipate new requirements during development. computer application (app) the central computer that provides services (such as database access) to the client computers over a network.
In computing, a server is a computer program or a device that provides functionality for other programs or devices, called "clients".This architecture is called the client–server model, and a single overall computation is distributed across multiple processes or r-bridal.coms can provide various functionalities, often called "services", such as .
A collection of system-level software that manages a computer's hardware resources and provides common services to computer programs running on the computer.
It is a vital component of the system software in a computer system. Programs and applications usually require an this to function.
Introduction. This article provides a step-by-step procedure for installing a new instance of SQL Server , using the SQL Server setup installation wizard. An instance of Analysis Services is a copy of the r-bridal.com executable that runs as an operating system service. Each instance is fully independent of other instances on the same. Apr 30, · The client application attempts to use TCP/IP to connect to a SQL Server Analysis Services instance on a computer that exists, is reachable, on which SQL Server Analysis Services is installed and running, but the client application is unable to access any databases within the Analysis Services instance after connecting, due to .
