Oracle University - Oracle Database 11g: Performance Tuning - Seminar / Kurs von CNS Training & Consulting GmbH

Oracle University Kurs - 5 Tage

Students learn how to use Oracle Database 11g automatic tuning featuressuch as SQL Tuning Advisor, SQL Access Advisor, Automatic WorkloadRepository and Automatic Database Diagnostic Monitor, and practice thesetuning methods. The course focuses on the tuning tasks expected of aDBA: reactive tuning of SQL statements, maintaining SQL statementperformance, and tuning the Oracle Database Instance components.Throughout the course, students practice the art of tuning an OracleInstance through a series of workshops. The methodology is practiced inthe workshops rather than taught. This course does not address partitiontuning, materialized views, or RAC specific issues as they are coveredin courses specifically for these products. This course makes use ofmany features that require the Enterprise Edition and optional Packs.This course counts towards the Hands-on course requirement for theOracle Database 11g Administrator Certification. Only instructor-ledinclass or instructor-led online formats of this course will meet theCertification Hands-on Requirement. Self Study CD-Rom and KnowledgeCenter courses DO NOT meet the Hands-on Requirement.
