Cracking the Active/Active Data Warehouse Dilemma

For those of you who weren't at IOD this year, you may be interested to know that some of the presentations are now available on ibm.com.  The one about active-active data warehousing by Dwaine Snow, Linda Snow, and Enzo Cialini, all of IBM, is a good read that doesn't require you have a presenter handy.  It's pdf format can can be viewed or downloaded from the following link:

 

The covered points include:

  • Why active/active warehouses have become so important.
  • The definition of IBM's reference architecture for dual active warehousing.
  • How the various pieces fit in the dual active warehouse reference architecture:
    • Query Router's role in workload balancing
    • Q Replication's role keeping the warehouses synchronized
    • The IBM table compare utility's (asntdiff's) role in maintaining quality control

 

You'll probably need 15-20 minutes at most to go through the slides.
