Course Objectives
In this course, you learn how to use the advanced features of PL/SQL in order to design and tune
PL/SQL to interface with the database and other applications in the most efficient manner. Using the
advanced features of program design, packages, cursors, extended interface methods, and collections,
you learn how to write powerful PL/SQL programs. Programming efficiency, use of external C and
Java routines, and fine-grained access are covered in this course.

Oracle Complete Solution
The Oracle Internet Platform is built on three core components:
• Browser-based clients to process presentation
• Application servers to execute business logic and serve presentation logic to browser-based
clients
• Databases to execute database-intensive business logic and serve data
Oracle offers a wide variety of the most advanced graphical user interface (GUI)–driven
development tools to build business applications, as well as a large suite of software applications for
many areas of business and industry. Stored procedures, functions, and packages can be written by
using SQL, PL/SQL, Java, C, and Net languages. This course concentrates on the advanced features
of PL/SQL.

Agenda
In this three-day course, you start with a review of PL/SQL concepts before progressing into the new
and advanced topics. By the end of day one, you should have covered design considerations for your
program units, and how to use collections effectively.
On day two, you learn how to use advanced interface methods to call C and Java code from your
PL/SQL programs, how to implement and test fine-grained access control for virtual private
databases, how to manipulate large objects programmatically through PL/SQL, how to administer the
features of the new SecureFile LOB format of Database 11g, and how to tune PL/SQL code and deal
with memory issues.

Examining and Modifying Variables (continued)
The Classes window displays all classes that are currently being loaded to execute the program. If
used with Oracle Java Virtual Machine (OJVM), it also shows the number of instances of a class and
the memory used by those instances.
