How Big is Big Data?

How Big is Big Data? Enterprise data doubling every 3 years Storage capacity continue to increase dramatically - access speeds have not kept up At avg. transfer speed of 500 MB/sec - 1 TB of data will require ~30 mins to read from single drive

How Big is Big Data? Wal-Mart : 1M customer txs/hour, feeding 2.5 PB databases Facebook : 40Billion photos and increasing... Big Turkish Bank : 200 M txs/day, 0.06 second/tx UK Land Registery : The world’s largest known OLTP database – 71 TB at UK Land Registry

Existing Platforms and BIG DATA Decentral Central versus

Absolute Musts of Data Management Scalability Availability and DR Security Productivity , Utilization and Performance System Management Labor, Skills and Resources Green IT

Scalability i s the ability of a system to handle growing amounts of work in a graceful manner or its ability to be enlarged to accommodate that growth Scale-out or Horizontally Scale-up or Vertically

Availability and Disaster Recovery ... measures are classified by either the time interval of interest or the mechanisms for the system downtime Financial Impact of Downtime Per Hour What’s yours?? $704K Chemicals $669K Transportation $786K Consumer Products $997K Banking $1,082K Pharmaceuticals $1,107K Retail $1,202K Insurance $1,345K Information Technology $1,495K Financial $1,611K Manufacturing $2,066K Telecommunications $2,818K Energy Cost Industry segment 2h 11m 15h 20m Annual outage $3.3M $22.9M Cost of Downtime 99.975% 99.825% Availability % Central Decentral

Security protecting information from unauthorized access, use, disclosure, disruption, modification, perusal, inspection, recording or destruction . Last Year , Oracle issued 45 security patches Decentral Central 25 + Years of Secure Operation! In 20 years , DB2 for z/OS has had less than 5 security patches

Productivity , Utilization and Performance Utilization is the proportion of the system's resources which is used by the traffic which arrives at it Specific/Single Workload Mixed Workload Shared Nothing Shared Everything %15-20 Utilization %85-90 Utilization Decentral Central

System Management and Labor System Management is enterprise-wide administration of systems Is it true ? >:::> More Data needs More DBAs and System Management efforts! it highly depends!!! Running on Decentral or Central.

Green IT is environmentally sustainable computing . More Servers Less Servers More Power Less Power More Cooling Less Cooling Decentral Central More Space Less Space

BIG DATA management with DB2 for z/OS “ DB2 for z/OS” is IBM’s 25+ years old flagship database Used by; 62 of the top 62 WW banks 2 4 of the top 25 US retailers Over 100 of the largest Government ’ s in the world 9 of the top 10 global life/ health insurance provider s

BIG DATA management with DB2 10 for z/OS 20,000 thread/subsystem (2,000 for V9) Industry-leading Active/Active Clustering arch.
T op 3 IT issues today according to the 2010 IBM CIO St udy
Reduce Cost
Improve Service
Manage Risk
Up to 20% reductions in CPU Time Travel Query – IBM is 1 st in the Industry to provide integrated bi-temporal capabilities that is essential for Financial Services customers

BIG DATA management with DB2 10 for z/OS Native XML Processing DB2 10 for z/OS e nables SAP applications to have 6X the number of users and activities on a single system. Virtual storage improvements deliver 10X more scalability Industry leading Hardware Compression since V3 Complete SQL Portability between platforms V10 Introduced SMF Compression - For accounting mostly 80-90% - CPU Overhead %1

BIG DATA management with DB2 10 for z/OS DBADM without data access for all system SECADM on system level (zparm SECADM) Migration path options: Add Active log ONLINE w/o Stopping DB2 V7 V8 DB2 9 DB2 10

BIG DATA management with DB2 10 for z/OS Online Schema Enhancements: Alter the following stuff online  - page size of a table space - data set size of a table space - segment size of a table space - table space type - MEMBER CLUSTER structure for a table space - index page size

Performance improvement Categories for V10
Improvements that you receive by simply migrating to Version 10
Improvements that are implemented by DBA-level changes, without requiring application changes
Improvements that require application changes

Improvements that you receive by simply migrating to Version 10
- Out-of-the box savings in NFM  % 5-10-20
- Improved index matching for OR and IN predicates
- Parallelism enhancements such as for multi-row fetch
- Collection of autonomic statistics. Stored procedures will determine if statistics need to be collected then DB2 performs the collection.

Improvements that are implemented by DBA-
Level changes, without requiring application changes
- New Access Path: Hash Access
1- Queries use s equal predicates to access a single row
2- Tables of a predictable and reasonably static size.
- INCLUDE Clause for CREATE/ALTER Index
The use of INCLUDE columns is supported only on unique indexes

Improvements that require application changes
- Access to currently committed data it minimizes transaction suspension
1- a new bind option CONCURRENTACCESSRESOLUTION
2- New PREPARE statement clauses,
USE CURRENTLY COMMITTED which you can specify in the attribute-string

BIG DATA management with DB2 10 for z/OS Performance, Performance, Performance Delivered the largest banking benchmark ever at the Kookmin Bank in Korea , a record 15,353 transactions per second Supports the world’s largest known peak database workload - 1.1 Billion SQL statements per hour at UPS The world’s largest known OLTP database – 71 TB at UK Land Registry

Maturity of platform differs! Larry Ellison, Oracle's Founder and CEO “ I make fun of a lot of other databases – all other databases in fact, except the mainframe version of DB2. It's a first-rate piece of technology .”

Maturity of platform differs!

Top 10 in DB2 10 for z/OS
CPU reductions for transactions, queries, & batch
Ten times more users by avoiding memory constraints
More concurrency for catalog, utilities, and SQL
More online changes for data definition, utilities and subsystems
Improved security with more granularity
Temporal or versioned data
SQL enhancements improve portability
pureXML performance and usability enhancements
Hash, index include columns, skip migration, … Pick your favorite!
Productivity improved for database & systems administrators, and application programmers
