Book Description
This IBM® Redbooks® publication can help you tailor and configure DFSMS constructs to be used in an IBM DB2® 9 for z/OS® environment. In addition, it provides a broad understanding of new disk architectures and their impact in DB2 data set management for large installations. This book addresses both the DB2 administrator and the storage administrator. The DB2 administrator can find information about how to use DFSMS for managing DB2 data sets; the storage administrator can find information about the characteristics of DB2 data sets and how DB2 uses the disks. This book describes optimal use of disk storage functions in DB2 for z/OS environments that can best make productive use of the synergy with I/O subsystem on IBM System z®. This book covers the following topics: - Using SMS to manage DB2 catalog, log, data, indexes, image copies, archives, work files - Taking advantage of IBM FlashCopy® for DB2 utilities, striping, copy pools - Setting page sizes and using sliding allocation - A description of PAV, MA, MIDAW, EF, EA, EAV, zHPF and why they are helpful - Compressing data and the use disk and tape for large data sets - Backup and restore, and remote copy services

Book Description
Locking is the generic term used to refer to the database management system function that is required for managing interprocess concurrency and maintaining data integrity. However, locking is just one of the serialization mechanisms available in IBM℗ʼ DB2℗ʼ for z/OS℗ʼ. DB2 uses different mechanisms for serialization to achieve its goal of maximizing concurrency without losing integrity with a minimum cost in CPU, I/O, and storage resources. In this IBM Redbooks℗ʼ publication, we review and explore the different serialization mechanisms used in DB2, such as transaction (DML) locking, claims and drains, restrictive states, latching, and optimistic serialization. This book was written for application developers in order to help them better understand serialization mechanisms and how they influence application design decisions.

Book Description
IBM® continues to enhance the functionality, performance, availability, and ease of use of IBM DB2® utilities. This IBM Redbooks® publication is the result of a project dedicated to the current DB2 Version 9 Utilities Suite product. It provides information about introducing the functions that help set up and invoke the utilities in operational scenarios, shows how to optimize concurrent execution of utilities and collect information for triggering utilities execution, and provides considerations about partitioning. It also describes the new functions provided by several utilities for SHARE LEVEL CHANGE execution, which maximize availability and the exploitation of DFSMS constructs by the BACKUP and RESTORE SYSTEM utilities. This book concentrates on the enhancements provided by DB2 UDB for z/OS Version 8 and DB2 for z/OS Version 9. It implicitly assumes a basic level of familiarity with the utilities provided by DB2 for z/OS and OS/390® Version 7.

Book Description
This IBM® Redbooks® publication discusses in detail the facilities of DB2® for z/OS®, which allow complete monitoring of a DB2 environment. It focuses on the use of the DB2 instrumentation facility component (IFC) to provide monitoring of DB2 data and events and includes suggestions for related tuning. We discuss the collection of statistics for the verification of performance of the various components of the DB2 system and accounting for tracking the behavior of the applications. We have intentionally omitted considerations for query optimization; they are worth a separate document. Use this book to activate the right traces to help you monitor the performance of your DB2 system and to tune the various aspects of subsystem and application performance.

Book Description
IBM® DB2® Version 10.1 for z/OS® (DB2 10 for z/OS or just DB2 10 throughout this book) is the fourteenth release of DB2 for MVSTM. It brings improved performance and synergy with the System z® hardware and more opportunities to drive business value in the following areas: Cost savings and compliance through optimized innovations DB2 10 delivers value in this area by achieving up to 10% CPU savings for traditional workloads and up to 20% CPU savings for nontraditional workloads, depending on the environments. Synergy with other IBM System z platform components reduces CPU use by taking advantage of the latest processor improvements and z/OS enhancements. Streamline security and regulatory compliance through the separation of roles between security and data administrators, column level security access, and added auditing capabilities. Business insight innovations Productivity improvements are provided by new functions available for pureXML®, data warehousing, and traditional online TP applications Enhanced support for key business partners that allow you to get more from your data in critical business disciplines like ERP Bitemporal support for applications that need to correlate the validity of data with time. Business resiliency innovations Database on demand capabilities to ensure that information design can be changed dynamically, often without database outages DB2 operations and utility improvements enhancing performance, usability, and availability by exploiting disk storage technology. The DB2 10 environment is available either for brand new installations of DB2, or for migrations from DB2 9 for z/OS or from DB2 UDB for z/OS Version 8 subsystems. This IBM Redbooks® publication introduces the enhancements made available with DB2 10 for z/OS. The contents help you understand the new functions and performance enhancements, start planning for exploiting the key new capabilities, and justify the investment in installing or migrating or skip migrating to DB2 10.

Book Description
The goal of this IBM® Redbooks® publication is to demonstrate the ability to perform single click automated deployments of multi-platform applications that include IBM Db2 for z/OS database schema changes by using the capabilities of IBM Db2 DevOps Experience for z/OS. Pushing the application and database code changes to a source control management system (SCM) triggers a single CI/CD pipeline execution for application and database changes. Therefore, it mitigates the dependency on the DBA to deploy those database changes in a separate process. At the same time, DBAs can safeguard the integrity of their organization's data by implementing site rules in Db2 DevOps Experience. DBAs define whether a schema change can be approved automatically after all site rules are satisfied or whether it must be approved manually. In this publication, we provide an overview of the CI/CD pipeline architecture in the context of a sample application. We also describe the steps that are relevant to the roles of the DevOps engineer who implements the enterprise CI/CD pipeline, the DBA who is responsible for database code changes in Db2 for z/OS and for defining site rules that ensure quality in production, and the application developer who changes the application code and communicates requirements for changes in the database schema.
