This IBM Redbooks publication addresses the challenges posed by monitoring high availability, scalability, and performance in an SAP sysplex data sharing environment. It introduces the motivations for utilizing a design based on DB2 data sharing. It includes the principal SAP-DB2 data sharing architecture options and trade-offs used in the industry today and issues that play a role in both high availability and scalability, such as failover design, database connectivity design, workload splitting and load balancing, MCOD, and coupling facility design. The book discusses single point of failure, important failover scenarios and outage avoidance, automation of high availability constructs, and backup and recovery considerations in data sharing environments. Performance issues are detailed in the order you would approach them at planning and implementation time. First, it discusses tuning the sysplex, which is the base for a well-performing DB2 data sharing system, then tuning the DB2 data sharing system, which is the base for a well-performing SAP system, and finally, tuning the SAP system. The book focuses on initial planning for performance and monitoring it afterward, and explains the key points to look for to health-check your system and maintain high performance.

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.

Data is one the most critical and valuable assets of a business. Critical strategic decisions can be made more quickly and effectively when they are based on complete, accurate, and timely operational data. From this point of view, it is important to have an enterprise data management architecture that supports a flexible global view of the business. Many environments today are heterogeneous with a high quantity and diversity of data. In this IBM® Redbooks® publication, we help enterprise architects and IT managers with these environments make decisions for a centralized database or data warehouse. We recommend a centralized data management environment on Linux® on System z®. We include guidance for IBM z/VSETM and Linux specialists to reorganize existing IBM DB2® VSE data and build a database environment with continuous operation in Linux on System z. We begin this book by describing the possibilities and advantages of enterprise data management and different technical ways to realize it. Then we discuss planning, which is important for setting the foundation of the architecture that is implemented. We explain the hardware considerations for capacity and performance planning. For the z/VSE system and Linux on System z, we describe considerations for operation in a logical partition (LPAR) and in a virtualized environment with IBM z/VM®. In addition, we discuss the disk behavior for different workloads, storage dependencies, network connections, and DB2 database considerations. We also guide you in customizing the DB2 server for z/VSE, z/VM, and DB2 on Linux to allow existing z/VSE and z/VM applications to access the database on Linux on System z. We include the data migration, application considerations, dependencies, compatibility, monitoring, and tuning possibilities in such an environment.

DB2® packages were introduced with DB2 V2.3 in 1993. During the 15 years that have elapsed, a lot has changed. In particular, there is a more widespread use of distributed computing, JavaTM language, new tools, and upgrades in the platform software and hardware. The best practices back then just might not be optimal today. In this IBM® Redbooks® publication, we take a fresh look at bringing packages into the 21st century. We begin with an overview of packages and explain the advantages of using packages. Because database request module (DBRM) based plans have been deprecated in DB2 9, you need to convert to packages if you did not use packages already. We provide guidance on using a DB2 provided function to convert from DBRM-based plans to packages. We re-examine the application development frameworks for packages: program preparation, package setup, and execution. For distributed applications, we include a discussion of a utility to identify and remove deprecated private protocol and converting to DRDA® as well as an introduction to the new pureQuery function of Data Studio. We also discuss common problems and their resolutions. We then explore administration and operational activities dealing with packages, including security, access path management (where we discuss the newly introduced package stability feature to allow for a seamless fallback), and management and performance aspects. The appendixes include useful queries and mention tools for managing packages effectively.
