Hi DB2 user,

IBM just published a draft version of a new Redbook "DB2 11 for z/OS Technical Overview, SG24-8180-00":
http://www.redbooks.ibm.com/redbooks.nsf/RedpieceAbstracts/sg248180.html?Open

Abstract
IBM DB2 11 for z/OS is the fifteenth release of DB2 for MVS. It brings performance and synergy with the new System z hardware and new opportunities to drive business value in the following areas:
Unmatched reliability, availability, and scalability

Improved data sharing performance and efficiency
Even less downtime by removing growth limitations
Simplified management, improved autonomics, and reduce planned outages
with more online schema changes and utilities improvements
Save money, save time

Aggressive CPU reduction goals
Additional utilities performance and CPU improvements
Save time and resources with new autonomic and application development capabilities
Simpler, faster migration
SQL compatibility, divorce system migration from application migration
Access path stability improvements
Better application performance with SQL and XML enhancements
Enhanced business analytics

Faster, more efficient performance for query workloads
Accelerator enhancements
More efficient inline database scoring enables predictive analytics
The DB2 11 environment is available either for brand new installations of DB2, or for migrations from DB2 10 for z/OS subsystems only.

This IBM Redbooks publication introduces the enhancements made available with DB2 11 for z/OS. The contents help database administrators understand the new functions and performance enhancements, start planning for exploiting the key new capabilities, and justify the investment in installing or migrating to DB2 11.

Redbook Security Functions with DB2 10 for z/OS

Hi User,

IBM just published a draft version of a new Redbook "Security Functions with DB2 10 for z/OS, SG24-7959-00":
http://www.redbooks.ibm.com/Redbooks.nsf/RedpieceAbstracts/sg247959.html?Open

Abstract
DB2 9 and 10 for z/OS have added functions in the areas of security, regulatory compliance, and audit capability which provide solutions for the most compelling requirements.
DB2 10 enhances the DB2 9 role-based security with additional administrative and other finer-grained authorities and privileges. This authority granularity helps separate administration and data access that provide only the minimum appropriate authority.
The authority profiles provide better separation of duties while limiting or eliminating blanket authority over all aspects of a table and its data. In addition, DB2 10 provides a set of criteria for auditing for the possible abuse and overlapping of authorities within a system.
In DB2 10, improvements to security and regulatory compliance focus on data retention and protecting sensitive data from privileged users and administrators. Improvements also help to separate security administration from database administration.
DB2 10 also lets administrators enable security on a particular column or particular row in the database complementing the privilege model.
This IBM® Redbooks® publication provides a detailed description of DB2 10 security functions from the implementation and usage point of view.

Redbook DB2 10 for z/OS Performance Topics

Hi User,

IBM just published a draft version of a new Redbook "DB2 10 for z/OS Performance Topics, SG24-7942-00":
http://www.redbooks.ibm.com/abstracts/sg247942.html?Open

Abstract

DB2 10 can reduce the total DB2 CPU demand from 5-20% 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.
