    Kurzfassung: Time to market, flexibility, and cost reduction are among the top concerns common to all IT executives. If significant resource investments are placed in mature systems, IT organizations need to balance old and new technology. Older technology, such as non-IBM pre-relational databases, is costly, inflexible, and non-standard. Users store their information on the mainframe and thus preserve the skills and qualities of service their business needs. But users also benefit from standards-based modernization by migrating to IBM® DB2® for z/OS®. With this migration, users deliver new application features quickly and respond to changing business requirements more effectively. When migrating, the main decision is choosing between conversion and re-engineering. Although the rewards associated with rebuilding mature applications are high, so are the risks and customers that are embarking on a migration need that migration done quickly. In this IBM Redbooks® publication, we examine how to best approach the migration process by evaluating the environment, assessing the application as a conversion candidate, and identifying suitable tools. This publication is intended for IT decision makers and database administrators who are considering migrating their information to a modern database management system. Please note that the additional material referenced in the text is not available from IBM.

    Kurzfassung: The DB2® pureXML® feature offers sophisticated capabilities to store, process and manage XML data in its native hierarchical format. By integrating XML data intact into a relational database structure, users can take full advantage of DB2's relational data management features. In this IBM® Redbooks® publication, we document the steps for the implementation of a simple but meaningful XML application scenario. We have chosen to provide samples in COBOL and Java™ language. The purpose is to provide an easy path to follow to integrate the XML data type for the traditional DB2 for z/OS® user. We also add considerations for the data administrator and suggest best practices for ease of use and better performance.

    Kurzfassung: IBM® DB2® 9 and 10 for z/OS® have added functions in the areas of security, regulatory compliance, and audit capability that provide solutions for the most compelling requirements. DB2 10 enhances the DB2 9 role-based security with additional administrative and other finer-grained authorities and privileges. This authority granularity helps separate administration and data access that provide only the minimum appropriate authority. The authority profiles provide better separation of duties while limiting or eliminating blanket authority over all aspects of a table and its data. In addition, DB2 10 provides a set of criteria for auditing for the possible abuse and overlapping of authorities within a system. In DB2 10, improvements to security and regulatory compliance focus on data retention and protecting sensitive data from privileged users and administrators. Improvements also help to separate security administration from database administration. DB2 10 also lets administrators enable security on a particular column or particular row in the database complementing the privilege model. This IBM Redbooks® publication provides a detailed description of DB2 10 security functions from the implementation and usage point of view. It is intended to be used by database, audit, and security administrators.

    Kurzfassung: 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.

    Kurzfassung: The requirements for a database management system (DBMS) have included support for very large and complex data objects. DB2 UDB for OS/390 Version 6 introduced the support for large objects (LOBs): they can contain text documents, images, or movies, and can be stored directly in the DBMS with sizes up to 2 gigabytes per object and 65,536 TB for a single LOB column in a 4,096 partition table. The introduction of these new data types has implied some changes in the administration processes and programming techniques. The book Large Objects with DB2 for z/OS and OS/390, SG24-6571, introduced and described the usage of LOBs with DB2 for z/OS at Version 7 level. Major enhancements for LOB manipulation have been introduced with DB2 UDB for z/OS Version 8 and DB2 Version 9.1 for z/OS (DB2 9 in this book). These enhancements include performance functions such as the avoidance of LOB locks and DRDA LOB flow optimization, usability functions such as file reference variables, FETCH CONTINUE, and the automatic creation of objects. DB2 utilities provide integrated support with LOAD and UNLOAD, Cross Loader, REORG, CHECK DATA, and CHECK LOB. In this IBM Redbooks publication, we provide a totally revised description of the DB2 functions for LOB support as well as useful information about how to design and implement LOBs. We also offer examples of their use, programming considerations, and the enhanced processes used for their administration and maintenance. We also detail how SAP solutions use LOBs. This book replaces the previous book, Large Objects with DB2 for z/OS and OS/390, SG24-6571, for DB2 Version 8 and Version 9.1. Please note that the additional material referenced in the text is not available from IBM.

    Kurzfassung: DB2 for z/OS takes advantage of data sharing technology in a z Parallel Sysplex to provide applications with full concurrent read and write access to shared DB2 data. Data sharing allows users on multiple DB2 subsystems, members of a data sharing group, to share a single copy of the DB2 catalog, directory, and user data sets. Data sharing provides improvements to availability and capacity without impacting existing applications. The road to data sharing might seem arduous to a novice user, but once you have started to learn terminology and gain basic understanding, things will become much easier. This IBM Redbooks publication is meant to facilitate your journey towards data sharing by providing a cookbook approach to the main tasks in enabling data sharing and workload balancing. It does not have all the answers, because it is a brief summary of a large field of knowledge, but it contains the key elements and it points you in the right direction to get more details. Throughout this document we assume that your sysplex environment is set up and a DB2 subsystem exists at a currently supported level.

    Kurzfassung: Conducting business via the Web and remaining open for business 24 hours a day, seven days a week is now commonplace. Customers come in with unexpected workloads through the Web and operate in a self-service fashion with mostly context-sensitive metadata to guide them. The strong requirement is availability. However, even with new Web applications, most of the core business systems considerations still apply, and performance is critical. Technology has been accelerating for mainframe systems. They had become adept at providing business resiliency accommodating strategic software that has been around for the last several decades such as IMS™ , DB2® , and CICS® , and they have also become a host for developing and running Web applications built in Java™ accommodating the latest business requirements. Businesses need to leverage, extend and integrate the strategic assets which represent multi-year investments to support leading edge technology. DB2 for z/OS® has come a long way and provides facilities to exploit the latest hardware and software technologies, accommodating a majority of user requirements. However, special considerations are required to build high performance applications. If you want to achieve high performance or high availability, you must use the design, programming, and operational techniques applicable to DB2. In this IBM Redbooks publication we discuss many of these techniques and provide guidelines for database and application design. We expect the best practices described in this book will help DB2 professionals design high-performance and high-availability applications. Please note that the additional material referenced in the text is not available from IBM.

    Kurzfassung: DB2 provides functions to guarantee integrity at the system level and at the application level. From the system point of view, DB2's integration with zSeries and disk storage architecture is the cornerstone for data integrity. Logging functionality and COPY and RECOVER utilities are the building blocks for bringing the table space back to a current or consistent status in case of hardware or software failures or when application events need to be rerun. From the application point of view, DB2 supports locking and commit at the transaction level, and general data integrity (at entity and semantic level), and a set of referential constraint rules for each parent/dependent table relationship. The tables linked by referential integrity are recognized during the execution of the QUIESCE utility. Other logical relations across tables, necessary to support business rules, are implemented via constraints, triggers, user defined functions, and user defined tables. Informational constraints also exist, they are not enforced by the database manager, they are used to improve query performance. In this IBM Redbooks publication, we briefly describe the integration of DB2 for z/OS with System z architecture, we then explore the data integrity options and utilize the standard recovery functions for application-related issues.

    Kurzfassung: Moving data across different databases and even different platforms has been a common task in IT shops for quite some time. Applications may have been developed independently and over time, using packages and different technology; and data might reside on different platforms exploiting the specific platform strong points. However, there still is a growing need for applications that need to access all of this data for overall processing. While new Web related technologies are emerging with the intent to provide functions to collect and integrate information across multiple databases and applications for access in real time, moving data to one location for overall processing is still a very common requirement. This IBM Redbooks publication provides an overview of what is currently available within the DB2 Family of products (specifically DB2 for z/OS, and DB2 for UNIX and Windows) in terms of functions, tools, and utilities to satisfy the need for moving data. We focus on discussing High Performance Unload and Cross Loader; the first one is a tool, the second one is a new option of the Load utility, since they are the latest functions that IBM has released. We also introduce the concepts and some examples of using the Federated Database support.

    Kurzfassung: Performance measurements are ongoing during the life of each release of DB2 for OS/390. DB2 for z/OS and OS/390 Version 7 (DB2 V7 throughout this document) has introduced several enhancements in the areas of performance and availability, and other enhancements are currently being added. Most of these enhancements and the related performance measurements implemented in the Silicon Valley Laboratory have been documented in the IBM Redbooks publication DB2 for z/OS and OS/390 Version 7 Performance Topics, SG24-6129. However, information on new DB2 functions and their synergy with the evolving zSeries platform is of great value for strategic investments, and more performance measurements are under way. Currently these measurements have included topics such as FICON, Java support, CICS interface, and DB2 OLAP Server. This book is meant to provide an update on the new measurements that have been implemented, and to point out the performance related maintenance that has been shipped after general availability of DB2 for z/OS Version 7. The information here contained is intended to help managers and professionals understand and evaluate the applicability to their environment of these recent functions of DB2 V7. This book replaces the IBM Redpaper that was made available in February 2002, with the same title, and provides more up-to-date information.
