Oracle DBA Workshop-II

Affiliation:
Duration: 2 days

Course Objective :

This Oracle Database 11g: Administration Workshop II Release 2 training takes the database administrator beyond the basic tasks covered in the first workshop. You’ll begin by gaining a deep understanding of the most important responsibilities a DBA has: performing backup and recovery.

Ensure fast, reliable, secure and easy to manage performance. Optimize database workloads, lower IT costs and deliver a higher quality of service by enabling smooth and rapid consolidation within your Datacenter.

The concepts and architecture that support backup and recovery, along with the steps required to execute it in various ways and situations, are covered in detail. You’ll learn how to define and test your own backup and recovery scenarios.

You’ll also learn how to manage memory effectively, as well as how to perform some performance evaluation and tuning tasks. Instructors will review all types of flashback technologies, scheduling jobs inside and outside of the database and controlling system resource usage.

This course counts towards the Hands-on course requirement for the Oracle Database 11g Administrator Certification. Only instructor-led in class or instructor-led online formats of this course will meet the Certification Hands-on Requirement. Self-Study and Knowledge Center courses DO NOT meet the Hands-on Requirement.

  • Configure the Oracle Database for optimal recovery
  • Configure the database instance such that resources are appropriately allocated among sessions and tasks
  • Schedule jobs to run inside or outside of the database
  • Use compression to optimize database storage and duplicate a database
  • Back and recover a database (and its parts) with RMAN (command-line and Enterprise Manager)
  • Use flashback technology to view past states of data and to revert either objects or the entire database back to a past
  • state
  • Use an appropriate and flexible memory configuration for your database
  • Identify burdensome database sessions and poorly performing SQL

Target Audience :

The demand for Oracle technical professionals is growing at an incredible pace. But individuals, experienced or new to the profession, need to know what skills make them attractive to employers. Employers look for ways to distinguish employees and prospective employees who have the solid foundation of skills needed for effective performance.  The expertise of Oracle database administrators (DBAs) is integral to the success of today’s increasingly complex system environments. Their critical work requires a broad understanding of the architecture and processes of the Oracle database, as well as plenty of hands-on experience in solving problems. The best DBAs know they stand between optimal performance and an event that could bring their company to a standstill.
