Course Overview

The PL/SQL programming language is at the core of most Oracle database applications. This training will give attention to three fundamental pillars of effective implementation of PL/SQL applications. First, we will explore the advanced features of the language that allow powerful and adaptable database applications to be built. Next, we will discuss performance tuning techniques that allow these applications to run efficiently. Finally, we will consider critical security measures that should be implemented to counter hacker attacks and other security threats.

This course considers subjects applicable to certification as an Oracle Advanced PL/SQL Developer Certified Professional (OCP). The topics considered are included within ‘Exam 1Z0-146: Oracle Database Advanced PL/SQL.’

What you’ll learn

• Invoking external procedures and integrating these into PL/SQL applications. These include external Java classes using the JDBC interface and external C programs contained within DLL libraries.
• Using dynamic SQL to extend the functionality and flexibility of database programs, including the DBMS_SQL() system-supplied package for maximum flexibility.
• Identifying SQL injection attack vulnerabilities within an application and applying countermeasures to address security risks and protect against hacking.
• Incorporating collections and other advanced types into application logic to increase efficiency and execution speed. • Working with LOBs, including piecewise data manipulation and dynamic modification of SecureFiles storage options.
• Expanding database application functionality with advanced system-supplied database utility packages, integrating one’s applications with external mail systems, database internals, and other facilities.
• Tuning with the DBMS_PROFILER() system-supplied package and debugging with the DBMS_TRACE() system-supplied package.
• Writing efficient PL/SQL code and avoiding common coding mistakes.
• Enabling native compilation and execution of all database-resident program units.
• Controlling and managing PL/SQL compilation for high-efficiency execution.
• Analyze PL/SQL code structure by means of the PL/Scope facility.
• Analyze PL/SQL application performance and tune bottlenecks using the PL/SQL Hierarchical Profiler.
• Implementing fine-grained security mechanisms as part of an advanced security model using application contexts and the Oracle virtual private database (VPD).
• Dynamic partitioning and DML parallelization using the system-supplied package DBMS_PARALLEL_EXECUTE().
• Using the wrap utility to hide the source code of database-resident programs, even from the owner or authorized users of the programs.
