In the DB2 for z/OS Utility manual, you can read that an incremental image copy is a copy of the pages that have changed since the last full or incremental image copy. Incremental copies are faster and produce smaller image copy files.

Image Copies play an important role in any DB2 recovery process. A normal DB2 recovery has three major parts:

SMS stands for System Managed Storage, short for Data Facility Storage Management Subsystem (DFSMS), which is an integral part of z/OS . SMS is composed of a set of components designed to make disk storage management easier and more efficient.

On Wednesday October, 3 IBM announced “IBM DB2 11 for z/OS Early Support Program”. IBM intends to make DB2 11 for z/OS (DB2 11) available to a select group of clients in a closed Early Support Program (ESP) on March 8, 2013.

It is already two years ago that the top mainframe model z196 was introduced by IBM. On August 28, 2012, IBM announced a new mainframe model called the IBM zEnterprise EC12 (in short zEC12).

Are you planning for DB2 10 on the mainframe? Then IBM has some excellent white papers available for you! You will find everything you need to cost justify the upgrade or explain what is new and useful for your company.

In my previous article, I talked about how to use the DB2 HADR feature as a tool to migrate data. Here is another cool method I discovered (entirely by accident) during one of my hair tearing migration sessions with the application team. I must say in all fairness the application team had more of a tough time than me, but once I discovered this cool feature in DB2  and tested it, I was able to sit back, relax and enjoy all the hustle and bustle that the application team had to go through.

In this article you can read about an unconventional and cool way of using the DB2 HADR  tool for data migration. I  presented this method of using the DB2 High Availability Disaster Recovery feature as a tool to migrate a database  for the 2011 spring “DB2’s got talent” contest series hosted by Scott Hayes of the popular DB2 Night Show.

“Single sign-on” is a dream that for many for us is impossible. Servers, servers and more servers is what we are facing nowadays. And single sign-on is simply not possible because…

In our day to day job the use of internet is nowadays permitted in the larger companies. Software vendors store their manuals, white papers and software updates online so you can easily download it. There are two potential “problems” with downloading information

In 2010 I did extensive research on extended explain tables. This post shows the results of my research.
