A draft, a book and a technote

If you haven't got a clue what I'm talking about, then shame on you : three types of publications you find on the IBM Redbook site. The book is the final product while a draft is a publication that's not yet entirely finalized, but is already worth publishing on the site. A Technote is a short, usually very practical text, on one particular subject.

The book : 'DB2 9 for z/OS: Distributed Functions'
It consists of 4 parts
  • Distributed Database architecture and configurations : the authors "introduce the concepts and protocols of DRDA and describe the layout and the components of the possible configurations where DB2 for z/OS can play a client or server role"
  • Setup and Configuration : "a description of the steps needed for the installation of a distributed environment"
  • Distributed Applications : Application programming and data sharing
  • Performance and problem determination
The book also contains lots of samples.
And if you live in the Belgian region, you might want to go to the joint DB2-CICS-SOA GSE meeting next Thursday where there's also a session on 'Talking with DB2 for z/OS : today's distributed connectivity options'.

The Draft : 'Batch modernization on z/OS'
"As a large portion of the workload on z/OS is processed in a batch mode, it is not difficult to justify a dedicated publication on this matter.
These days there are many different technologies that can be put at work in a batch environment on z/OS. This Redbook demonstrates that batch on z/OS is not only COBOL, JCL and a job scheduler anymore. This book also demonstrates that z/OS offers a sophisticated environment for batch that you may not have implemented on z/OS yet.
(...) The book also includes a chapter on future developments in batch processing."

The Technote : 'Converting LPAR Weights to Logical Processor Allocation'
Plain and simple, but useful : "This Tip describes how to calculate the portion of a shared logical processor assigned to an LPAR."
--> Link seems to be no longer working. Workaround : you can Google for lpar weight redbooks. It gives you the non-working link to the document, but you can still find it via the 'in cache' link.

The "Batch Modernization for z/OS" is very nice one. It's nice to read about PHP in batch mode!

It seems the technote about LPAR weights doesn't exist.

yes, you're right. It seems to be gone. I'll take a closer look as soon as I can.

Just checked again : it actually seems to be gone.
If you want it, you can Google for lpar weight redbooks. It gives you the non-working link to the document, but you can still find it via the 'in cache' link.
