Brent Phillips - 20 May 2016

While most mainframe shops have explored how to reduce mainframe software costs, at IntelliMagic we are finding significant latent savings opportunities still exist at even the best run sites.

Since software cost reduction is always important, we thought it would be helpful to pass along a valuable resource from the March 2016 SHARE Conference for mainframe users, which included a new session by Todd Havekost of USAA, a Fortune 100 financial services company.

Mr. Havekost’s presentation ‘Achieving Significant Capacity Improvements on the IBM z13’ outlined the results of their software cost optimization initiatives. Part of the story is that some of the historical capacity planning assumptions no longer apply and how lowering RNI reduced both MIPS and the cost of IBM Monthly Licensing Charge (MLC) software. The session has been identified as outstanding and the winner of the SHARE Best Session Award.

The content is an excellent overview of industry-leading optimization efforts, and explores z13 capacity concepts, key processor hardware metrics, and the results for USAA. Our own software, IntelliMagic Vision, is used for numerous charts in his presentation.

Todd’s initiatives resulted in a reduction of 13,000 MIPS for USAA, as documented in the following slide from the presentation:

After the presentation, one of the IBM Distinguished Engineers that attended the presentation said that USAA is the first site he is aware of that has performed this type of detailed z13 performance analysis and optimization.

Because Todd Havekost is one of the country’s leading experts in this area of mainframe software cost reduction, we recently hired Todd to lead the comprehensive MLC optimization initiatives for IntelliMagic customers, using IntelliMagic Vision for z/OS.

“IntelliMagic Vision meets a critical need in today’s mainframe environments by applying embedded subject matter expertise against the rich set of SMF metrics. The result is the ability to proactively identify threats to mainframe availability,” Todd said. ”Best of all, the flexible reporting interface provides unparalleled visibility into performance data to identify system inefficiencies and MLC reduction opportunities.”

To schedule a no-charge evaluation of the latent software MLC reduction opportunities at your mainframe site, please contact us for a no-obligation review of your environment.



Health Insights and Change Detection

To help enhance the value you can derive from that SMF data, IntelliMagic Vision provides two complementary types of automated anomaly detection: health insights and change detection.

CICS Max Tasks: Automated Change Detection Use Case 7

Change Detection and Health Assessments (based on pre-defined best practice conditions) play complementary roles, but there can be scenarios where they both flag issues. This use case with CICS Max Tasks is one such example.

Batch Job Elapsed Time: Automated Change Detection Use Case 6

Elapsed and CPU times can be of interest for batch jobs, especially those on the critical path for key business job cycles. This use case reflects an abnormally long run time for a daily batch job, and illustrates how potential causes might be investigated.

How to use Processor Cache Optimization to Reduce z Systems Costs

Optimizing processor cache can significantly reduce CPU consumption, and thus z Systems software costs, for your workload on modern z Systems processors. This paper shows how you can identify areas for improvement and measure the results, using data from SMF 113 records.
