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.

Redbook DB2 9 for z/OS: Using the Utilities Suite

Bonjour,

IBM vient de mettre à disposition une version de travail d'un nouveau Redbook intitulé, "DB2 9 for z/OS: Using the Utilities Suite, SG24-6289-01" :
http://www.redbooks.ibm.com/Redbooks.nsf/RedpieceAbstracts/sg246289.html?Open

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.

Part 1. Introduction
Chapter 1. Introduction
Chapter 2. Backup and Restore utilities
Part 2. Planning for DB2 utilities
Chapter 3. Managing partitions
