Book Description
This IBM® Redbooks® publication provides advice and guidance for IBM z/OS® Version 1, Release 10 and subsystem system programmers. z/OS is an IBM flagship operating system for enterprise class applications, particularly those with high availability requirements. But, as with every operating system, z/OS requires planned IPLs from time to time. This book also provides you with easily accessible and usable information about ways to improve your mean time to recovery (MTTR) by helping you achieve the following objectives: - Minimize the application down time that might be associated with planned system outages. - Identify the most effective way to reduce MTTR for any time that you have a system IPL. - Identify factors that are under your control and that can make a worthwhile difference to the startup or shutdown time of your systems.

Book Description
Understanding the impact of workload and database characteristics on the performance of both DB2®, MQ, and the replication process is useful for achieving optimal performance.Although existing applications cannot generally be modified, this knowledge is essential for properly tuning MQ and Q Replication and for developing best practices for future application development and database design. It also helps with estimating performance objectives that take these considerations into account. Performance metrics, such as rows per second, are useful but imperfect. How large is a row? It is intuitively, and correctly, obvious that replicating small DB2 rows, such as 100 bytes long, takes fewer resources and is more efficient than replicating DB2 rows that are tens of thousand bytes long. Larger rows create more work in each component of the replication process. The more bytes there are to read from the DB2 log, makes more bytes to transmit over the network and to update in DB2 at the target. Now, how complex is the table definition? Does DB2 have to maintain several unique indexes each time a row is changed in that table? The same argument applies to transaction size: committing each row change to DB2 as opposed to committing, say, every 500 rows also means more work in each component along the replication process. This RedpaperTM reports results and lessons learned from performance testing at the IBM® laboratories, and it provides configuration and tuning recommendations for DB2, Q Replication, and MQ. The application workload and database characteristics studied include transaction size, table schema complexity, and DB2 data type.

Book Description
IBM WebSphere Application Server for z/OS V6 is a complex product made up of many components. This IBM Redbooks publication focuses on the problems that you can experience with WebSphere for z/OS. It is intended for system programmers and administrators who need to identify, analyze, and fix problems efficiently so that they can deliver good support for the WebSphere environment. In Part 1, we provide an overview of problem determination methodology, what skills you need, where to find information about related topics, and how to communicate with IBM when a problem occurs. In Part 2, we describe the most common problem symptoms. Flow charts guide you through the problem analysis process step by step. Individual tasks and questions help you filter out irrelevant facts and find the problem area, so that you can identify the type, source, cause, and possibly a solution. In Part 3, we identify possible problem areas and arrange them into four phases that correspond with WebSphere for z/OS life cycle stages. We explain how to analyze the problems and provide valuable hints and tips for avoiding them. In Part 4, we provide means and tools for problem determination such as commands, logs, dumps, traces, and diagnostic tools. We describe other tools that can ease the day-to-day tasks and prevent problems. We also explain where to get these tools, show you how to use them, and provide examples. Please note that the additional material referenced in the text is not available from IBM.

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.
