Here is a sample chapter for download. The chapter covers the Tracing and Profiling capabilities of Oracle PL/SQL.
I shall welcome the honest reviews from the readers so that I can fill the gaps between my efforts and reader’s expectations. In addition, if you feel to provide additional feedback on other aspects of the book, you are always welcome. Do write me at my blog for any deviation in observation or understanding.
The content outline of the book is as below
Chapter 1, Overview of PL/SQL Programming Concepts
The chapter covers the overview of PL/SQL as the primary database programming language. It describes the characteristics of the language and its strengths in database development. The chapter paces up with the structure of a PL/SQL block and reviews the PL/SQL objects like procedures, functions, and packages. In the chapter, we shall also learn to work with SQL Developer.
Chapter 2, Designing PL/SQL Code
The chapter discusses the handling of cursors in a PL/SQL program. The readers would learn the guidelines to design a cursor, usage of cursor variables, and cursor life cycle.
Chapter 3, Using Collections
The chapter introduces a very important feature of PL/SQL i.e. Collections. A collection in database is very similar to arrays or maps in other programming languages. The chapter compares the collection types in multiple aspects and makes fair recommendations for the appropriate selection in a situation. The chapter will also teach the collection methods which are utility APIs for working with collections.
Chapter 4, Using advanced interface methods
The chapter teaches how to interact with an external program written in non PL/SQL language, within PL/SQL. The chapter demonstrates the execution steps of external procedures in PL/SQL. The steps describe the network configuration on a database server (mounted on Windows OS), library object creation and publishing of a non-language program as an External routine.
Chapter 5, Implementing VPD with Fine Grained Access Control
The chapter introduces the concept of Fine Grained Access in PL/SQL. The working of FGAC as Virtual Private Database is explained in detail along with an insight on its key features. The readers would find stepwise implementation of VPD with the help of policy function and DBMS_RLS package. The chapter describes the policy enforcement through application contexts also.
Chapter 6, Working with large objects
The chapter discusses the traditional and conventional way of handling Large Objects in Oracle database. The chapter starts with the familiarization of available LOB data types (i.e. BLOB, CLOB, BFILE and Temporary LOBs) and their significance. The readers would learn the creation of LOB types in PL/SQL and their respective handling operations. The chapter demonstrates the management of LOB data types using SQL and DBMS_LOB package.
Chapter 7, Using SecureFile LOBs
The chapter introduces one of the key inductions of Oracle 11g i.e. SecureFiles. SecureFiles are upgraded LOBs which work on improved philosophy of storage and maintenance. The key accomplishments of SecureFiles i.e. deduplication, compression and encryption are licensed features. The chapter discusses and demonstration the implementation of these three properties. The readers would learn how to migrate (or rather upgrade) the existing older LOBs into new scheme i.e. SecureFiles. The migration techniques covered use online redefinition method and partition method.
Chapter 8, Compiling and Tuning to improve performance
The chapter describes the fair practices in effective PL/SQL programming. The readers would surely arouse great interest in discovering the fact that how a better code writing impacts the code performance. Besides, the chapter explains an important aspect of query optimization i.e. the parameter PLSQL_OPTIMIZE_LEVEL. The code behavior and optimization strategy at each level would help the readers to understand the language internals. Subsequently, the new PRAGMA induction will give the readers a deeper insight into subprogram inlining concepts.
Chapter 9, Caching to improve performance
The chapter covers another hot feature of Oracle 11g database i.e. Server side result caching. The newly introduced server side cache component in SGA holds the results retrieved from SQL query or PL/SQL function. The chapter describes the configuration a database server for caching feature through related parameters, implementation in SQL through RESULT_CACHE hint and implementation in PL/SQL function through RESULT_CACHE clause. Besides the implementation part, the chapter teaches the validation and invalidation of result cache and using DBMS_RESULT_CACHE package.
Chapter 10, Analyzing PL/SQL Code
The chapter is meant to understand and learn the code diagnostics tricks and using the code analysis for reporting purposes. The readers would learn to monitor identifier usage, compilation settings and generate the subsequent reports from SQL Developer. The chapter body discusses a very important addition of Oracle 11g, the PL/Scope. It covers the explanation and illustrations to generate the structural reports through the dictionary views. In addition, the chapter also demonstrates the use of DBMS_METADATA package to retrieve and extract metadata of database objects from the database in multiple formats.
Chapter 11, Profiling and tracing PL/SQL Code
The chapter aims to demonstrate the tracing and profiling features in PL/SQL. The tracing demonstration uses DBMS_TRACE package to trace the enabled or all calls in a PL/SQ program. The PL/SQL hierarchical profiler is a new induction in 11g to identify and report the time consumed at each line of the program. The biggest benefit is that the raw profiler data can be reproduced meaningfully into HTML reports.
Chapter 12, Safeguarding PL/SQL Code against SQL Injection attacks
The chapter discusses the SQL injection as a concept and its remedies. The SQL Injection is a serious attack on the vulnerable areas of the PL/SQL code which can lead to extraction of confidential information and many fatal results. The readers would learn the impacts and precautionary recommendations to avoid the injection attacks. The body of the chapter discusses the preventive measures like using invoker’s rights, client input validations tips, and using DBMS_ASSERT to sanitize inputs. The chapter concludes on the testing strategies which can be practiced to identify vulnerable areas in SQL.
Mock Assessment Test for 1Z0-146 Exam
