Beta Customers’ Feedback – Workload level Workload Results

Distributed Concurrent Insert

50% DB2 elapsed time reduction

15% chargeable CPU reduction after enabling high perf DBAT

CICS online transactions

Approx. 7% CPU reduction in DB2 10 CM after REBIND, 4% reduction with 1MB page usage

No CPU reduction after using hash access

CICS online transactions

Approx 5% CPU reduction

Data sharing heavy concurrent insert

38% CPU reduction

Queries Average CPU reduction 28% from V8 to DB2 10 NFM

Batch Overall 28% CPU reduction after rebind packages

Beta Customers’ Feedback – Line Item Focused

Workload Results

Multi row insert 33% CPU reduction from DB2 9, 4x improvement from V8 due to LRSN spin reduction

Parallel Index Update 30-40% Elapsed time improvement with class 2 CPU time reduction

Inline LOB SELECT LOB shows 80% CPU reduction

Include Index 17% CPU reduction in insert after using INCLUDE INDEX

Hash Access 20-30% CPU reduction in random access

The best candidates for hash access are random single row access into a table with a fixed, know size, with many rows per page, and with small variation in row sizes. Changes made very late in beta for improvements.

Sample Improvements

� Run time CPU reductions 5% - 10%

� 1 MB page size 0% - 4% z10, z196

� Release deallocate 0% - 15% short trans, batch

� Virtual storage constraints 0% - 5% memory, latches

� Improved dynamic SQL cache 0% - 20% literals

� Insert 0% - 40% high volume insert

� Predicate evaluation 0% - 60% complex predicates

� Access: hash, index include 0% - 5% access improved

� Increased use of zIIP 0% - 3% IO, RUNSTATS, par

� Temporal, security priceless

Vast majority of beta customers plan on moving to production in 2011

“We have measured a 38% reduction in CPU for heavy insert

workloads in a data sharing environment. That’s a significant

savings which provides immediate business benefit.”

Peter Paetsch, BMW Group

“We expect to reduce our data sharing requirements by 25%, which

means less system, storage and resource expenses.”

Banco do Brasil

“The new temporal functionality in DB2 10 for z/OS will allow us to

drastically simplify our data-related queries and reduce our

processing cost by having DB2

handle data movement more efficiently than

our custom code.”

Large Insurance Company

“As much as 80% of our applications can use this, which will

drastically save developer time and even more importantly make

applications easier to understand to improve business efficiency

and effectiveness.”

“In addition to the cost savings, DB2 10 for z/OS offers a far

superior data server environment than Oracle.”

Manuel Gomez Burrierl, CECA

(Spanish Bank Federation)

“As a multi-national corporation, we must adhere to strict local audit

requirements. The security and administration capabilities in DB2 10

are a key driver for us to move to this version.”

• Significant savings in processing costs

• Up to 6 times the number of SAP users on a single system

• Time Travel temporal capabilities built directly into the database

• Direct Row access accelerates high performance applications
