Latest overview of DB2 and its increasing momentum in HK

a moment to

break out of an

IT comfort zone



Agenda

� If IBM DB2 help you :

– Reduce IT operation expense

– Improve IT resource utilization

– Enhance IT service level

� Why now and how ?



The current IT spending climate after crisis

� Global economic crisis

� IT budgets flat or declining

� Data volumes still growing

� Increasing cost of managing data

“…businesses should prepare now for cutting

IT costs, and the data management

discipline is one area that affords

numerous opportunities for reducing and

controlling costs. In most cases, the cost of

implementing the steps will be far outweighed by the savings that can be realized.”

In 2009, executives face challenging global

economic conditions that have not existed for

more than 50 years...IT spending budgets will

be essentially flat.

Worldwide IT Spending



� June 2008 Oracle drastically increases the price of all their software– Increase range from 15% to 47%– Also affects maintenance bills

� March 2009 Oracle increases the price of the Oracle Database by 33% on some platforms

� July 2009 Oracle increases the price of pretty-much required Management and Tuning packs by over 40%

� August 2009: Doubled the price of Active Data Guard

Don’t Forget…Oracle Has Ratcheted Up Prices

Oracle Enterprise : US 48,800 => US 57,950 (18.75% increment)



But decreasing support level

( 完全失敗完全失敗完全失敗完全失敗)



Now a database market share turning point

Growth Growth

in USD Constant Currency

Database & Middleware - reported by Oracle -22% -19%

all Database, incl. options -24% -21%

core Database only -26% -23%

Database options only -21% -18%

Oracle Q1 result ( 16-Sep-2009 )



Oracle Database Features Supported by DB2 9.7

Oracle DBMS �� DB2 9.7

Oracle Concurrency Control �� No change

Oracle SQL �� No change

Oracle PL/SQL �� No Change

Oracle Packages �� No Change

Oracle Built-in packages �� No Change

Oracle JDBC �� No Change

Oracle SQL*Plus Scripts �� No Change

Changes are the exception. Not the rule.

THIS IS WHY WE CALL IT ENABLEMENT AND NOT PORT !

PL/SQL = Procedural Language/Structured Query Language



Utilize your existing Oracle development skill & application on DB2

� Why do you need DB2 development Skill ?

� When you can use Oracle skill develop program on DB2.

� The database market has changed…



Reason 1 : Cost on Software

� For example a Enterprise Edition Dual Core Intel (pre-helium) :– Oracle EE : US 87,596

• + Data Guard + Partitioning • + Tuning Pack + Diagnostic Pack

– DB2 EE ( inc. HADR & Table Partitioning) : US 40,500• Inc. HADR, Table Partitioning• Health Centre, Activities Monitor, Design Advisor etc.

� For Standby Server charging :– DB2 charge only 1xCPU on idle standby server– DB2 NO CHARGE for cold standby

� Oracle Standard vs DB2 Workgroup vs MSSQL ( socket )• Include first year support and subscription

– Microsoft SQL Enterprise Edition : US 35,146– Oracle Standard Edition : US 21,350– DB2 Workgroup Edition : US 15,000



Reason 2 : Lightning Fast

“Before we made a final decision we benchmarked some of the key database management systems. That includes Oracle, SQL Server and DB2. We ended up choosing DB2 for several reasons. One was reliability, second was performance and perhaps the most important factor was ease of use”– Bashir Khan, Director of Data Management , Dow Jones

� Save money by getting more from your hardware with DB2

� Better Transactional Performance

– 50% Faster than Oracle

– 5X Faster than Microsoft

� Better BI Performance

– 65% Faster than Oracle

– 5X Faster then MicrosoftResults as of June 5, 2008



Reason 3 : Great Performance without Tuning

� DB2 tunes itself so you don’t have to

worry about the database

� Use DB2’s Self Tuning Memory

Manager– Configures DB2 without needing a DBA

– Get your system running quickly in

minutes with little skills or training

– Only need to set one memory parameter

� Impact?– DBAs no longer spend time on menial tasks

– DBAs focus on business critical projects

“The autonomic features are going to save me 30% to

35% of my support costs.”

– Bob Maddocks, Maddocks Systems

Integration DB2 with AIX

� Process Exploitation (thread, SMT, NUMAtization of DB2 resources, +++

� Memory Exploitation (larger page sizes, multi page support, co-operative Caching, +++

� Storage Exploitation (Async I/O, Scatter/Gather I/O, CIO, DIO, Atomic LVs+++ Volumes

� Unique Enablement for POWER6 features (Dec Floating Point, Storage Keys)

� Deep integration with AIX APIs

� Exploits xlC for optimal performance using Profile Directed Feedback

� And many, many more …



DB2 9.5 - Memory Simplification

� AIX threading greatly simplifies DB2’s memory model –one big flat address space

Oracle's own explanation on how thread is better

� http://download.oracle.com/docs/cd/B28359_01/win.111/b32010/architec.htm#i1005670

� A thread-based architecture provides the following advantages:– Faster context switching– Simpler System Global Area allocation routine, because it does not require use of

shared memory– Faster spawning of new connections, because threads are created more quickly than

processes– Decreased memory usage, because threads share more data structures than

processes

� http://download.oracle.com/docs/html/B13831_01/ap_unix.htm#i634536

� On UNIX, Oracle Database uses a process to implement each of such background tasks as database writer (DBW0), log writer (LGWR), shared server process dispatchers, and shared servers. Each dedicated connection made to the database causes another operating system process to be spawned on behalf of that session.

� On Windows, each background process is implemented as a thread inside a single, large process. For each Oracle Database instance or system identifier, there is one corresponding process for Oracle Database.



Part of technical advancement in DB2 for WAS

� SQLj deployment in WebSphere Application Server

� PureQuery support in WebSphere Application Server

� ��DB2 trusted context support

� ��Extended DB2 data source support

� DB2 client reroute enhancements in WebSphereApplication Server

� ……



DB2 & Websphere

� SQLj deployment in WebSphere Application Server• Installation of SQLj applications from WebSphere Application

Server administrative console. • Customization and binding of DB2 SQLj profiles from

administrative console without the need to uninstall and reinstall applications



DB2 now allow both Shared-disk or Shared-Nothing scale out design
