z/OS Developer Software              


zHISR generates a "hot spot" analysis of customer, vendor or operating system program execution.

zHISR normalizes sample data between faster zIIP and zAAP engines and slower sub-capacity coprocessors.

 Compared to other z/OS performance product zHSIR is extremely capable and priced inexpensively which is why SAS Institute

and Rocket Software have become avid customers.

 Phoenix Software is known for its E-JEZ Software with Ed Jaffe their CTO.

Tuesday December 4th

Registration for SPARTA meeting SAS Campus


Frank Kyne, technical consultant.  Prior to joining Watson & Walker, Frank was a project leader in the IBM Redbooks organization, responsible for Redbooks on Parallel Sysplex, high availability, and performance.


Abstract: Software Pricing – The New Frontier in System Tuning

We (mainframers) have years of experience with addressing poor application response times (break down the response time, find the largest component, and address with faster I/O, more buffers, eliminate paging, etc) or batch job turnaround delays (Analyze submit-to-completion times, find the largest component, and address with initiator tuning, I/O reduction, service class adjustments, etc).   So why not view software pricing through the same lens?  The metric is dollars rather than seconds, but the approach is similar - Analyze your bill to identify its constituent parts, eliminate waste (no longer used products), then focus on reducing the peak MSUs or the cost of those MSUs – the toolkit is the same, except that you now have even more tools (software pricing options) to address your problem.


This Event will be held on SAS Campus

Please feel free to invite anyone that you know that might be interested. Guests are free.

                                                                        Shadowdiskz Webinar

Here is the invitation for November 15th at 11:00 AM EST


If you use z/VM and z/Linux this webinar should be very interesting.


ShadowDisk/Z is a software implementation to z/VM which allows multiple Linux virtual machines to transparently share part or all of a virtual Linux file system, without altering the base FS


Key Benefits


        Significantly reduces test/developer disk requirements for multiple-user Linux application testing

        Significantly lessens FS backup/restore requirements, since the DB contains only active FS blocks.

        Databases can be shared among multiple users.

        Utilities provided to query, backup, and restore ShadowDisk/Z databases.

        Provides for the creation of databases which do not require a base FS (NOBASE option).


Join us for a live overview of ShadowDisk and a demonstration of the Key Benefits above.
