Oracle Database Performance Tuning - Optimizer Statistics Gathering
 
04:51
In this video we explain how to gather the database optimizer statistics #performancetuning, #oracledatabase, #oracle, #database, #optimizerstatistics, #learning, About Optimizer Statistics Collection In Oracle Database, optimizer statistics collection is the gathering of optimizer statistics for database objects, including fixed objects. The database can collect optimizer statistics automatically. You can also collect them manually using the DBMS_STATS package. Purpose of Optimizer Statistics Collection The contents of tables and associated indexes change frequently, which can lead the optimizer to choose suboptimal execution plan for queries. To avoid potential performance issues, statistics must be kept current. To minimize DBA involvement, Oracle Database automatically gathers optimizer statistics at various times. Some automatic options are configurable, such enabling AutoTask to run DBMS_STATS. Stats collection Stats gathering database performance tuning, 10g, 11g 12c database administration

PL/SQL tutorial : Trigger in Oracle Database 11g Complete guide
 
26:21
Learn in depth about trigger in oracle database 11g, and usage of trigger in Database, different types of trigger with syntax for various events along with writing advance trigger and capturing all details regarding authentication. Explained Instead of trigger. Trigger in Oracle, Trigger in PL/SQL, Oracle Trigger, PL/SQL Trigger, What is Trigger in pl/sql, How to use Trigger in pl/sql, How to write a Trigger in oracle, How to design Trigger in pl/sql, DDL trigger, DML trigger, Instead of trigger, Compound trigger, Logon trigger, Introduction to Triggers You can write triggers that fire whenever one of the following operations occurs: DML statements (INSERT, UPDATE, DELETE) on a particular table or view, issued by any user DDL statements (CREATE or ALTER primarily) issued either by a particular schema/user or by any schema/user in the database Database events, such as logon/logoff, errors, or startup/shutdown, also issued either by a particular schema/user or by any schema/user in the database Triggers are similar to stored procedures. A trigger stored in the database can include SQL and PL/SQL or Java statements to run as a unit and can invoke stored procedures. However, procedures and triggers differ in the way that they are invoked. A procedure is explicitly run by a user, application, or trigger. Triggers are implicitly fired by Oracle when a triggering event occurs, no matter which user is connected or which application is being used. How Triggers Are Used Triggers supplement the standard capabilities of Oracle to provide a highly customized database management system. For example, a trigger can restrict DML operations against a table to those issued during regular business hours. You can also use triggers to: Automatically generate derived column values Prevent invalid transactions Enforce complex security authorizations Enforce referential integrity across nodes in a distributed database Enforce complex business rules Provide transparent event logging Provide auditing Maintain synchronous table replicates Gather statistics on table access Modify table data when DML statements are issued against views Publish information about database events, user events, and SQL statements to subscribing applications Linkedin: https://www.linkedin.com/in/aditya-kumar-roy-b3673368/ Facebook: https://www.facebook.com/SpecializeAutomation/

Solving Performance Problems on Oracle DB
 
28:11
Solving Performance Problems on Oracle DB Matthew Vegh - Embarcadero Thursday, June 26, 2014 - 11am DBAs and database developers regularly spend a lot of time tracking down and resolving performance issues on the database servers they are responsible for; it can be very difficult, frustrating, and expensive. Given the complex interactions of applications, users and databases, new performance issues can arise almost as fast as old ones can be addressed. This session will simulate common performance problems on an Oracle server and then both identify those problems and provide effective solutions. Matthew Vegh is a Software Architect at Embarcadero Technologies for the Embarcadero DB Power Studio family of products and has been with the company for the better part of a decade. He has over 15 years of development experience with a wide range of technologies and a definite preference for database tooling.

SQL SERVER PART-12: Oracle Linked Database Server
 
03:46
HOW TO CREATE LINKED SERVER AND HOW TO QUERY ORACLE DATABASE FROM SQL SERVER MANAGEMENT STUDIO. SQL server 2017 makes it easy to configure linked server. You can use open-query to get or manipulate data of linked server database. CONFIGURATION SUMMARY: PROVIDER : oracle provider for oledb. DATA SOURCE : It is usually a combination of oracle server IP: port number/t.n.s listener name. e.g. 192.168.1.10:5121/orcl OPEN QUERY : select * form openquery(linked_server_name, ' sql query statement ') Configure a linked server to enable the SQL Server Database Engine to execute commands against OLE DB data sources outside of the instance of SQL Server. Typically linked servers are configured to enable the Database Engine to execute a Transact-SQL statement that includes tables in another instance of SQL Server, or another database product such as Oracle. Many types OLE DB data sources can be configured as linked servers, including Microsoft Access and Excel. Linked servers offer the following advantages: • The ability to access data from outside of SQL Server. • The ability to issue distributed queries, updates, commands, and transactions on heterogeneous data sources across the enterprise. • The ability to address diverse data sources similarly. An oracle linked server require OLE DB provider. An OLE DB provider is a DLL that manages and interacts with a specific data source. If your oracle database is not in same server then you have to install The Oracle Data Access Components (ODAC) for Windows consists of Oracle client side drivers. An OLE DB data source identifies the specific database that can be accessed through OLE DB. Although data sources queried through linked server definitions are ordinarily databases, OLE DB providers exist for a variety of files and file formats. These include text files, spreadsheet data, and the results of full-text content searches. Typically, linked servers are used to handle distributed queries. When a client application executes a distributed query through a linked server, SQL Server parses the command and sends requests to OLE DB. The row set request may be in the form of executing a query against the provider or opening a base table from the provider.

Recognizing patterns in a sequence of rows has been a capability that was widely desired, but not possible with SQL until now. With Oracle Database 12c Release 1 (12.1), you can use the MATCH_RECOGNIZE clause to perform pattern matching in SQL.
