Thanks to T-zine where I found this.

First, the prerequisites :
- z196 Enterprise System processor with AWLC pricing
- z/OS V1.10, or higher, with SMF APAR OA31615
- Installation and use of SCRT V19.2.0
- Use of the SCRT IWP control statement
What's the story ? You might remember that some IPLA softwares are eligible for Getting Started Subcapacity Pricing. For example, a Web Application Server is running in a large partition with a rather small workload. Normally, this IPLA software is execution-based. So you have to buy as many Value Units as needed to cover for the entire LPAR. With the Getting Started pricing, the workload of the Websphere Application Server is measured and you only have to have enough Value Units to cover for the actual workload - following certain rules of course.
Now, with Integrated Workload Pricing (IWP) we go one step further. In the announcement you find a list of Websphere IPLA products which are called the defining programs. Next to that there's a list of MLC programs which are eligible to be adjusted by IWP. This boils down to let's say all CICS and IMS versions. The MSUs of these softwares are lowered based on the utilisation of the defining programs, which have to be present in the same LPAR.
How is this calculation done ?
"SCRT calculates the 4-hour rolling average of the general purpose processor time consumed by the IWP Defining Programs and subtracts those values from the traditional sub-capacity values for the MLC programs eligible to be adjusted by IWP, on an hour by hour basis, per LPAR". This can give you a lower MSU value for your CICS and/or IMS products.
You can find more information on Software Pricing on the IBM System z Software Pricing page and there's also already a section on IWP pricing.

The reason for this is very similar to the reason expressed for raising the price for DB2 V8. CICS TS 3.1 has been around since 2005 and lots of new functionalities (also with release 3.2) have been added over the years without any price increase. IBM also guarantees that it will continue to support V3 at least until September 2013. But apparently all this comes with a certain price . . .
Here's the argumentation of the authors to write this Redbook :
"One of the greatest strengths of Parallel Sysplex is its flexibility. Parallel Sysplex can be exploited by the largest corporations with huge sysplexes, and by small customers with just a single processor. However, this flexibility can also be a challenge. With so many options, how do you know what is the best way to configure a sysplex to achieve your objectives? And with so many demands for your time, how can you possibly keep up with all the latest recommendations for how to set up your sysplex?The Redbook is divided into several chapters treating Parallel Sysplex with regards to z/OS, CICS, DB2, IMS, MQ and WAS.
This book makes it easier for you to obtain the latest guidance for your Parallel Sysplex in one succinct and easy-to-use place. Configuring your sysplex to adhere to these guidelines does not guarantee that you will never encounter an outage again, but it should result in a more resilient configuration that delivers improved levels of service".

"(...) many DB2 users are considering migration and need direction in planning the right migration strategy for their business.Roger Miller will discuss the following topics :
But how do you approach a migration strategy?
When is the best time to start?
Is skipping a release a good strategy?
What are the costs versus benefits for any scenario?"
- Defining migration plan details for each component in your environment — servers, clients, applications and routines
- Incorporating steps from previous migration plans, including internal procedures to request access, software installation or other system services
- Understanding product restrictions and recommendations in order to plan your migration strategy

Apparently the situation has changed now as we read in this article from The Register : 'IBM's mainframe-blade hybrid to do Windows'. This article does not only give a good recap of the (concepts of the) zEnterprise System, it also gives us some insights in its future, as told by some IBM people. I quote :
"The (...) change that's coming with the zBX, according to Doris Conti, director of System z marketing at IBM, is that Microsoft's Windows operating system will be supported on the Xeon blade servers inside the zBX complex. IBM has hosted over 300 workshops with mainframe customers discussing the new hybrid system, and customers were not exactly happy that IBM was restricting Linux to Xeon blades and not supporting Windows.
'We heard the feedback and we very much intend to deliver Windows support on zBX,' says Conti."
Mind you, no specific date has been given, nor with which hypervisor it will be implemented on the zBX. If we deduce a timescale we now will first see the Xeon-based blades with Linux. Afterwards IBM seems to go for the Windows implementation. Then "if mainframe shops want to run the IBM i 7.1 operating system (formerly known as OS/400) on Power blades, IBM will consider it, says Conti". Linux on Power seems to have the lowest priority for the moment.
Never thought I would give one of my posts a 'Windows' label.
As I always say, just check it out !

Possible corrupted backup copy for z/OS 1.10, 1.11, 1.12 users of zHPF (High Performance FICON) & PDSE users with PTF's for OA30025 or OA34009 applied..
Only users performing logical dumps of PDSE data sets under the following conditions, (this is also true for HSM BACKUP and MIGRATION):
- PTF's for OA30025 or OA34009 are installed
- The PDSE to be backed up resides on a device which supports zHPF channel programs
- zHPF processing is enabled
PDSE backups taken after the installation of PTFs for OA30025 or OA34009 should be considered as suspect.
Please see APAR OA35260 (Media Manager) & OA35296 (PDSE) for additional information.
- Apply ++APARs for OA35260 & OA35296 as soon as possible, or
- Backoff PTF's for OA30025 and/or OA34009, or
- Disable zHPF until ++APAR can be applied
