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."
