Identify the nature of the program which is best suited for the interpreted mode of compilation.
The program unit contains multiple SQL statements.
The program unit has been just developed and is in debug stage.
The program unit uses collections and bulk bind statements.
The program unit is in production phase.
Choose the correct statements about the real native compilation mode in Oracle 11g;
The compilation method uses C compiler to convert the program into the equivalent C code.
The compilation method mounts the shared libraries through the
PLSQL_NATIVE_LIBRARY_DIR
andPLSQL_NATIVE_LIBRARY_SUBDIR_COUNT
parameters.The compilation does not use C compiler but converts the program unit directly to the M code.
The real native compilation is supported for RAC environments and participates in the backup recovery processes.
Determine the behavior of the
PLSQL_OPTIMIZE_LEVEL
optimizer when it has been set to3

Overview of this book
PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension language for SQL and the Oracle relational database. Server-side PL/SQL is stored and compiled in the Oracle Database and runs within the Oracle executable. With this guide Oracle developers can work towards accomplishing Oracle 11g Advanced PL/SQL Professional certification, which is the second milestone for developers working at the Associate level. The Oracle Advanced PL/SQL Developer Professional Guide helps you master advanced PL/SQL concepts. Besides the clear and precise explanation on advanced topics, it also contains example code and demonstrations, which gives a sense of application and usage to readers.The book gives a deep insight that will help transform readers from mid-level programmers to professional database developers. It aims to cover the advanced features of PL/SQL for designing and optimizing PL/SQL code.This book starts with an overview of PL/SQL as the programming database language and outlines the benefits and characteristics of the language. The book then covers the advanced features that include PL/SQL code writing using collections, tuning recommendations using result caching, implementing VPD to enforce row level security, and much more. Apart from programming, the book also dives deep into the usage of the development tool SQL Developer, employing best practices in database environments and safeguarding the vulnerable areas in PL/SQL code to avoid code injection.
