Redbook DB2 9 for z/OS and Storage Management

Bonjour,

IBM vient de mettre à disposition une version de travail d'un nouveau Redbook intitulé, "DB2 9 for z/OS and Storage Management, SG24-7823-00" :
http://www.redbooks.ibm.com/Redbooks.nsf/RedpieceAbstracts/sg247823.html?Open

Résumé
This book addresses both the storage administrator and the DB2 administrator. The DB2 administrator will find information on how to use DFSMS for managing DB2’s data sets. The storage administrator will find information on the characteristics of DB2 data sets and how DB2 uses the disks. We describe optimal use of disk storage functions in DB2 for z/OS environments which can best exploit the synergy with I/O subsystem on System z.

The addressed topics include the following:
- Using SMS to manage DB2 catalog, log, data, indexes, image copies, archives, workfiles.
- Taking advantage of FlashCopy for DB2 utilities, striping, copypools.
- Setting page sizes and using sliding allocation.
- PAV, MA, MIDAW, EF, EA, EAV. What they are and why they are good for you.
- Compressing data and indexes and the use disk and tape for very large data sets.
- Backup and Restore, and remote copy services recommendations.

Redbook DB2 9 for z/OS: Resource Serialization and Concurrency Control

Bonjour,

IBM vient de mettre à disposition un nouveau Redbook intitulé, "DB2 9 for z/OS: Resource Serialization and Concurrency Control, SG24-4725-01" :
http://www.redbooks.ibm.com/Redbooks.nsf/RedbookAbstracts/sg244725.html?Open

Résumé
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 DB2 for z/OS. 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 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.

Résumé
IBM continues to enhance the functionality, performance, availability, and ease of use of 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 on introducing the functions which help in setting up and invoking the utilities in operational scenarios, it shows how to optimize concurrent execution of utilities, collect information for triggering utilities execution, and considerations on 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 impicitly assumes a basic level of familiarity with the utilities as provided by DB2 for z/OS and OS/390 Version 7.

Redpaper DB2 9 for z/OS: Buffer Pool Monitoring and Tuning

Bonjour,

IBM vient de mettre à disposition une version de travail d'un nouveau Redpaper intitulé, "DB2 9 for z/OS: Buffer Pool Monitoring and Tuning, REDP-4604-00":
http://www.redbooks.ibm.com/redpieces/abstracts/redp4604.html

Résumé
DB2® buffer pools are a key resource for ensuring good performance.This is becoming increasingly important as the difference between processor speed and disk response time for a random access I/O widens in each new generation of processor.A System z® processor can be configured with large amounts of storage which, if used wisely, can help compensate by using storage to avoid synchronous I/O.
The paper is intended to be read by DB2 system administrators but may be of interest to any z/OS® performance specialist. It is assumed that the reader is familiar with DB2 and performance tuning.

Sommaire
- Describe the functions of the DB2 buffer pools
- Introduce a number of metrics for read and write performance of a buffer pool
- Make recommendations on how to set up and monitor the DB2 buffer pools
- Provide results from using this approach at a number of customers

Redbook DB2 9 for z/OS : Distributed Architecture

Bonjour,

IBM vient de mettre à disposition une version de travail d'un nouveau Redbook intitulé, "DB2 9 for z/OS: Distributed Architecture, SG24-6952-01" :
http://www.redbooks.ibm.com/Redbooks.nsf/RedpieceAbstracts/sg246952.html?Open

Résumé
Distributed Relational Database Architecture™ (DRDA® ) is a set of protocols that permits multiple local and remote database systems and application programs, to work together. Any combination of relational database management products that use DRDA can be connected to form a distributed relational database management system. DRDA coordinates communication between systems by defining what can be exchanged and how it must be exchanged.
DB2® for z/OS® Distributed Data Facility (DDF) is a built-in component which provides the connectivity to and from other servers or clients over the network. DDF is a full-function DRDA compliant transaction monitor which, equipped with thread pooling and connection management, can support very large networks. Different z/OS workload management priorities can be assigned to different, user-specified classes of DDF-routed application work.
In this IBM® Redbooks® publication we describe how to set up your DDF environment, and how to deploy the DDF capabilities in different configurations, including how to develop applications that access distributed databases.
We also describe a set of more advanced features, such as thread pooling and high availability distributed configurations, in a DB2 data sharing environment, as well as the traces available to you to do performance monitoring and problem determination.
In summary, we show how a high-volume, highly available transactional application can be successfully implemented with a DB2 for z/OS data server accessed by all types of application servers or clients running on the same or different platform.
