Oracle Database 11g R2: Advanced PL/SQL Programming and Tuning

This Oracle Database 11g R2: Advanced PL/SQL Programming and Tuning training class covers three fundamental pillars of effective implementation of PL/SQL applications. First, we will explore the advanced features of the language that allow powerful and effective database applications to be built. Next, we will discuss performance tuning techniques which allow these applications to run efficiently. Third, we will consider critical security measures which should be implemented to counter hacker attacks and other security threats.

The target audience for this course is senior application developers. Developers who will be building, debugging, and tuning PL/SQL program units will benefit from this course.

Goals
  1. Integrate external processes into PL/SQL applications.
  2. Use dynamic SQL to extend the functionality and flexibility of database programs,
  3. Identify SQL injection attack vulnerabilities within an application and applying countermeasures to address security risks and protect against hacking.
  4. Incorporating collections and other advanced types into application logic to increase efficiency and execution speed.
  5. Work with LOBs, including piece-wise data manipulation and dynamic modification of SecureFile storage options.
  6. Expand functionality with system-supplied database utility packages.
  7. Tune with the DBMS_PROFILER() system-supplied package and debugging with the DBMS_TRACE() system-supplied package.
  8. Write efficient PL/SQL code and avoid common coding mistakes.
  9. Enable native compilation and execution of all database-resident program units.
  10. Control and manage PL/SQL compilation for high-efficiency execution.
  11. Analyze PL/SQL code structure by means of the PL/Scope facility.
  12. Analyze PL/SQL application performance and tune bottlenecks using the PL/SQL Hierarachical Profiler.
  13. Recognize the dangers of SQL injection attacks against PL/SQL applications and applying countermeasures to this potential security threat from hackers.
  14. Implement fine-grained security mechanisms as part of an advanced security model using application contexts and the Oracle virtual private database (VPD).
