Download or read book Db2 Skeleton Cloning Protecting Your Production Environment written by Paul Bartak and published by IBM Redbooks. This book was released on 2017-11-27 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: IBM Db2® for z/OS® is well known as the gold-standard information steward. Deep synergy with the z/OS operating system and System Z platform provides support for the highest transaction volumes with the ultimate levels of availability. Just like any high-performance engine, occasional maintenance or upgrades are needed to maintain peak performance and to incorporate new features. Those that demand the highest standards and protection of their production environments know that you want to test changes outside of production first. It is common to have development or test environments for application development and verification. What about applying Db2 maintenance or performing migrations to new version or release levels? Sure, you probably perform these activities outside of production first, but are these environments similar enough to production to surface the same results as those you might encounter in production? Your production Db2 Catalog & Directory often has a different mix and complexity of objects, which were created at different levels of Db2, that can span decades of time. The best test of these activities is against your production system, but this is the system that we want to protect. How can we accomplish this? Clone it! Skeleton cloning produces a specific kind of clone, which provides a replica of the portions of your Db2 production environment that are needed to complete your testing. You can use the skeleton clone to find issues before they occur in production. This process allows you to refine maintenance steps in a safe environment and to minimize potential downtime when performing the same steps in a production system. This IBM® RedpaperTM publication gives a high-level overview of the IBM Db2 Cloning Tool and includes specific use cases for the tool. It also details the skeleton cloning process, which you can use to test migration, function levels, and maintenance, and includes demo examples that show a Db2 11 to 12 migration test using skeleton cloning.

Download or read book DB2 for Z OS Administration Tools for Enhanced Change Management written by Paolo Bruni and published by . This book was released on 2007 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book DB2 10 for z OS Performance Topics written by Paolo Bruni and published by IBM Redbooks. This book was released on 2013-08-23 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: DB2® 10 for z/OS can reduce the total DB2 CPU demand from 5-20%, compared to DB2 9, when you take advantage of all the enhancements. Many CPU reductions are built in directly to DB2, requiring no application changes. Some enhancements are implemented through normal DB2 activities through rebinding, restructuring database definitions, improving applications, and utility processing. The CPU demand reduction features have the potential to provide significant total cost of ownership savings based on the application mix and transaction types. Improvements in optimization reduce costs by processing SQL automatically with more efficient data access paths. Improvements through a range-list index scan access method, list prefetch for IN-list, more parallelism for select and index insert processing, better work file usage, better record identifier (RID) pool overflow management, improved sequential detection, faster log I/O, access path certainty evaluation for static SQL, and improved distributed data facility (DDF) transaction flow all provide more efficiency without changes to applications. These enhancements can reduce total CPU enterprise costs because of improved efficiency in the DB2 10 for z/OS. DB2 10 includes numerous performance enhancements for Large Objects (LOBs) that save disk space for small LOBs and that provide dramatically better performance for LOB retrieval, inserts, load, and import/export using DB2 utilities. DB210 can also more effectively REORG partitions that contain LOBs. This IBM Redbooks® publication® provides an overview of the performance impact of DB2 10 for z/OS discussing the overall performance and possible impacts when moving from version to version. We include performance measurements that were made in the laboratory and provide some estimates. Keep in mind that your results are likely to vary, as the conditions and work will differ. In this book, we assume that you are somewhat familiar with DB2 10 for z/OS. See DB2 10 for z/OS Technical Overview, SG24-7892-00, for an introduction to the new functions.
