How to Handle the “V” for Volume in Big Data on DB2 for z/OS

Posted by Frank Fillmore on March 14, 2013 under Big Data, DB2 for z/OS, IDAA, Netezza. Tags: , .

One of the challenges of Big Data is, well, its bigness.  There are two approaches you should consider – one fairly new, the other not yet delivered – for your data volume issues on DB2 for z/OS.

The first technique exploits the IBM DB2 Analytics Accelerator (IDAA).  IDAA is a Netezza (now PureData System for Analytics) appliance lashed together with DB2 for z/OS using a high-speed connection.  The same data typically resides in both DB2 and Netezza.  The DB2 optimizer determines if a particular dynamic query can be addressed at a lower cost by offloading that query to Netezza.

Until November 2012, all of the data needed to be present on both Netezza and DB2.  In IDAA version 3, that restriction has been removed.  The attached presentation describes offloading older data to the Netezza and eliminating it from DB2.  In a common use case the most current data (say, the last 30 days) remains in DB2, but older data (days 31 to the preceding 2 years) reside *only* in Netezza.  This is called the High Performance Storage Saver (HPSS).  IDAA HPSS

Based on the cost of mainframe DASD storage and other factors, it might be less expensive to store stale data in a “hot” back-end like the Netezza part of an IDAA than to continue to store that data natively in DB2 for z/OS.  From an API standpoint, you run your queries as if all of the data resides locally in DB2 for z/OS.  That way you can change which data reside in each of the IDAA components with out impacting applications or SQL changes.

The second technique exploits temporal data functionality delivered in DB2 10 for z/OS.  Temporal tables enable you to see values for attributes of a particular business object (account, part, employee, customer, etc.) at a specific point-in-time (PIT).  As SQL UPDATEs are processed against a transaction table, deltas are recorded in a history table associated with the transaction table.  That way you can issue a query like:

SELECT coverage_amt FROM policy FOR SYSTEM_TIME AS OF '12-01-2010' WHERE id = 111

and see the coverage_amt at a point-in-time regardless of any intervening changes.  DB2 11 for z/OS – not yet Generally Available (GA), but in beta with Early Support Program (ESP) customers – builds on this technology by extending it to “archive” data.  The use case is the same as the one described above: for processing efficiency you want the last 30 days of transaction data to reside in one DB2 table and older data (days 31 to the preceding 2 years) to be stored in another.  Think insurance claims: most activity regarding a claim occurs within the first 30 days of a loss.  But for business and compliance reasons, you want to retain up to 2 years of data on spinning disks; even older data might be kept on offline storage.  Using this technique, all of the data resides natively in two different DB2 for z/OS tables (current and archive).  The benefit this time is segregating commonly accessed data for processing efficiency.  As was the case with IDAA/HPSS, the location of the data is transparent to the SQL.  You write the query for the data you want and DB2 determines whether it resides in the current data table, archive table, or both.

Big Data Forum in Virginia

Posted by Kim May on March 11, 2013 under Big Data, Frank Fillmore, IBM Information Management Software Sales, IBM Pure Systems, Netezza, Optim, TFG Blog. Tags: , , , , , , .

I had the pleasure of attending and participating as a Business Partner in the IBM Big Data and Governance Forum road show event in Reston, Virginia, last week.  Many of the attendees were from Federal government agencies – no surprise – and most of the attendees, at least in my opinion, seemed to be trying to satisfy their curiosity about  Big Data. 

The first session presenter was Tracey Mustacchio, the Director of Marketing for Big Data.  Tracey came to IBM from Vivisimo, one of the latest IBM Information Management acquisitions.  She started her session with a standard show of hands opening.  The amazing thing was, with about 100 people in the room, only THREE were actually using any Big Data solutions in their IT shops.  3%!!  That meant – with the simplistic way I do math –  the other 97% of the attendees were, like me, still trying to figure out how to apply this new technology.  And of course, overcome the skepticism that comes from hearing a solution referred to as a “game changer” a few too many times.

The information delivered was excellent, with the presenters using clear, understandable business use case examples to demonstrate the Big Data solutions at work.  I thought it was great. 

As a Business Partner The Fillmore Group raffled off the gorgeous, huge coffee table book, “The Human Side of Big Data”, by Rick Smolan and Jennifer Erwitt.  After reading a glowing review I bought the book about a month ago for myself, and while I am bit overwhelmed by the book’s size (did I mention it’s huge?) which made it impossible to stuff in my laptop bag like my Kindle, it is simply beautiful and the perfect way to get excited about the potential of Big Data.  Each article is short – maximum length 2 pages – and tells about how Big Data has changed the way people are doing something.  And yes IBM fans, page 208 features Jeff Jonas.  Because what book about Big Data could leave out Jeff Jonas and his fascinating life and experience developing the IBM Entity Analytics solutions.

The forum delivered lots of great ideas and use cases.  It’s time to start moving beyond the ideas.  We all need to figure out how to apply this amazing technology and reap the benefits!  The next step, recommended by IBM’s Crysta Anderson, is to attend the IBM Big Data announcement on April 30th:   http://ibm.co/BigDataEvent to hear more about how you can move from theory to practice with Big Data.

New Netezza – aka “Striper” Announced

Posted by Kim May on February 5, 2013 under Big Data, DB2 for z/OS, IBM Pure Systems, Netezza, Sidecar, TFG Blog. Tags: , , , .

When IBM acquired Netezza the phenomenal processing capability enabled by the Netezza FPGA technology (Field Programmable Gate Arrays) made Netezza’s query speeds clear winners when benchmarked against all competitors.  Today IBM announced a new generation of Netezza, now branded the “IBM PureData System for Analytics”Powered by Netezza”, the N2001 systems.

The new N2001 system specs once again put Netezza into the “catch-me-if-you-can category, with a 3 times faster scan rate than the current Netezza, while supporting 50% greater storage capacity per rack, and improved resiliency and fault tolerance, thanks to more spare drives in the cabinet and faster drive regeneration.

The N2001 is available with the same quick, simple installation, and IBM also updated the IBM DB2 Analytics Accelerator, the “sidecar” Netezza that attaches to the mainframe.  More on the new sidecar soon – I hear the IDAA has even more capabilities to offer DB2 for z customers.  Stay tuned!
