March 2010- Unintended Consequences
We’ve all done it. You see a great new feature in DB2 and jump headling into using it without fully appreciating all of the implications. Here’s a case in point:
One of our clients is a large SAP customer running on DB2 for z/OS V9. With a huge number of subsystems to support and over 35,000 tables in each, taking traditional image copies would be a bit of a nightmare. Luckily, DB2 9 for z/OS contains the BACKUP/RESTORE SYSTEM function, which uses Flashcopy technology to rapidly backup and restore an entire system with a single utility. That means no messing with the traditional tablespace-level COPY utility, except when it’s needed for other reasons (such as when taking an inline image copy during an online REORG, to avoid putting the tablespace into COPY PENDING).
So far, so good. However, a couple of weeks ago the DBAs came in one morning to find a lot of SAP users complaining about database errors, and dozens of tablespaces unable to be updated due to being in a COPY PENDING state. What the heck happened?

In our first Confessions of a DB2 Geek podcast we chat to two of our DB2 experts about pureScale and what this important new release means for organisations running DB2 on midrange platforms.
An ideal fit for the retail sector, pureScale is going to allow organisations to increase capacity when they need it at the really busy times like Christmas and the January sales and scale back at times of less demand. Our DB2 LUW expert Clair says “If you’re a retailer with a high volume online transaction environment then pureScale is going to be absolutely ideal for you”
Just how important is this release to the midrange market?�
“For those needing true 24/7 availability this is an enormous release and has plugged a gaping hole that has been in the architecture of DB2 on midrange for some time.” James Gill, DB2 z/OS Expert
