In this age of complex regulatory oversight and wide ranging threats to corporate data, securing a company's information assets from internal and external threats has become a primary focus and concern for information professionals. IBM® understands these requirements and using features of the System z® hardware platform, DBMS and operating elements for DB2® on z/OS®, and Information Management tools can help to provide a defense in depth which can help to provide information confidentiality, integrity, and availability. We start with a description of the data governance requirements, with an emphasis on IBM Data Servers Blueprint including the IBM Data Server Security Roadmap, and general elements of a complete governance approach. Next, using the elements described in the first section, we position and map the specific elements and requirements of the Blueprint based scenario to IBM portfolio of security solutions. We then focus on some specific elements and capabilities of DB2 for z/OS and System z platform. These capabilities include elements such as network roles and trusted context, exploitation of network encryption capabilities with SSL and IPSec, and native DBMS Encryption. Included are System z hardware and z/OS operating system elements. Having laid a solid foundation with the previous components, we then take a deeper look at two specific IBM Information Management tools solutions. We build scenarios that demonstrate the use of the IBM Audit Management Expert for DB2 for z/OS. We take a deep div

IBM DB2 Recovery Expert manages the recovery of DB2 for z/OS V8 and V9 objects in a data sharing and non-data sharing environment. The major focus of IBM DB2 Recovery Expert V2.1 for z/OS (5697-N92) is on DB2 system level backup and restore. The tool provides the ability to create a consistent full system backup with no impact on DB2 availability, comprehensive backup and recovery reporting capabilities, and robust database and storage validity checking to ensure successful creation and usage of database system backups. By integrating with disk storage functions, it supports DB2 subsystem recovery from system backup, DB2 subsystem disaster recovery, and DB2 object data recovery from system backups. It also helps in selecting the most convenient recovery solution and in managing backups. This IBM Redbooks publication documents how to use Recovery Expert V2.1 for all restore and recovery functions related to system level backup. For scenarios of using Recovery Expert functions when recovering DB2 objects from traditional image copies, see the previous companion IBM Redbooks publication IBM DB2 Recovery Expert for z/OS User Scenarios, SG24-7226.

The cost-based optimizer of IBM DB2 for z/OS has continually evolved since its initial inception. Support has included new optimization algorithms, join methods, complex relational data structures, such as star schemas. DB2 for z/OS V8 has provided access path visualization and a Statistics Advisor function through a new Visual Explain. DB2 9 for z/OS starts addressing the challenge of reducing cost of ownership by extending query optimization through expert-based query and workload analysis, server enhancements, and an Index Advisory function. These functions are delivered with two tools: DB2 Optimization Service Center and DB2 Optimization Expert. This book helps you understand the installation, customization, and usage aspects of the tools. You are guided through scenarios of gradually increasing complexity where the functions of the tools are exploited for query optimization.

A database administrator (DBA) has a challenging job trying to maintain databases in today's nonstop 24x7 environments. This challenge is compounded by the complexity of database structures and the time pressure of trying to be up again as soon as possible without making mistakes. When business expands, several DB2 subsystems have to be maintained, such as multiple development systems, function test, acceptance test, volume test, and production systems. Often changes have to be implemented across multiple DB2 subsystems. The two IBM DB2 for z/OS tools that help database administrators to implement database changes are the DB2 Administration Tool and the DB2 Object Comparison Tool. In this IBM Redbooks publication we show how, with Version 7.2, the two tools offer an enhanced Change Management function to manage and track the changes of your DB2 objects. We show how the tools help you define changes, resolve conflicts, register the changes, analyze the changes to generate a work statement list that applies the changes, and then run the changes in the correct order. The Change Management functions also allow you to back out completed changes and facilitate the management of a convenient audit trail. This book contains a major update to the Change Management functions described in DB2 for z/OS Tools for Database Administration and Change Management, SG24-6420-01.

The goal of database performance tuning is to minimize the response time of your queries. It is also to optimize your server's resources by minimizing network traffic, disk I/O, and CPU time. This IBM Redbook helps you to understand the basics of identifying and tuning the performance of Structured Query Language (SQL) statements using IBM DB2 for i5/OS . DB2 for i5/OS provides a comprehensive set of tools that help technical analysts tune SQL queries. The SQL Performance Monitors are part of the set of tools that IBM i5/OS provides for assisting in SQL performance analysis since Version 3 Release 6. These monitors help to analyze database performance problems after SQL requests are run. In V5R4 of i5/OS iSeries Navigator provides a series of new tools to do SQL Performance analysis that we cover in this redbook. Among the new tools that we will covering are: - Capability of visualizing the contents of the SQE Plan Cache - SQE Plan Cache Snapshots - The new reporting tool - Dashboard - OnDemand Index Advisor - Evaluators such as Index and Materialized Query Tables This redbook also presents tips and techniques based on the SQL Performance Monitors and other tools, such as Visual Explain and all the tools provided in V5R4. You'll find this guidance helpful in gaining the most out of both DB2 for i5/OS and query optimizer when using SQL.

This IBM Redbook provides IMS performance monitoring and tuning information. This book differs from previous IMS performance and tuning IBM Redbooks in that there is less emphasis on the internal workings of IMS and more information about why and how certain options can affect the performance of IMS. Most of the information in the previous IBM Redbook IMS Version 7 Performance Monitoring and Tuning Update, SG24-6404, is still valid, and in most cases, continues to be valid in any future versions of IMS. This book is not an update or rewrite but instead attempts to be more of a guide than a reference. As such, the team gathered experiences and data from actual production environments as well as from IBM benchmarks and solicited input from experts in as many areas as possible. You should be able to find valuable new information and perhaps validate things you might have questioned. Hardware and software characteristics are constantly changing, but hopefully the information that you find here provides a basis to help you react to change and to keep your IMS running efficiently. In this IBM Redbook, we introduce methods and tools for monitoring and tuning IMS systems, and in addition to IMS TM and DB system-wide performance considerations, we dedicate separate chapters for application considerations, IMS and DB2 interoperability, the Parallel Sysplex environment, and On Demand considerations.

This IBM Redbook helps you design, install, manage, and tune stored procedures with DB2 for z/OS. Stored procedures can provide major benefits in the areas of application performance, code re-use, security, and integrity. DB2 has offered an ever improving support for developing and operating stored procedures. DB2's enhancements are related to tooling, language support, system environment, and have opened new possibilities for secure, highly portable applications in line with the e-business strategy of today's organizations. In this project we show how to develop stored procedures in several languages; we explore the new functions available for the z/OS platform deployment; and provide recommendations on setting up and tuning the appropriate stored procedure environment. The functions we have investigated include setting up the WLM environments, nesting stored procedure, invoking COBOL, C, REXX, SQL language programs, accounting, debugging options, special registers, and diagnostics. We have also set up, developed, and debugged Java stored procedures with the new Java universal driver in a DB2 for z/OS Version 8 environment. A chapter is devoted to DB2-supplied stored procedures. They can be used for almost all of a DBA's tasks. We start with the basic information, which is useful for the reader who is just beginning with stored procedures, but we also deal with more detailed and recent functionalities, which will be of interest for the more advanced users.
