Course Description
Course Objectives
Among the specific topics contained within these training materials are: 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 piece-wise data manipulation and dynamic modification of SecureFiles storage options. Expanding database application functionality with advanced system-supplied database utility packages, integrating ones 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.
