IMS 13 Quality Partnership Program


IMS 13 Quality Partnership Program

�Who participated– Representative cross section of the IMS

install base

– 2 Japanese customers + HATC (Japan)

–New QPP participant in production prior

to GA

� Their results–Highest quality rating in IMS history

– 3 customers in production prior to GA

– 7 customers in production as today

–More customers are upgrading now

300+ million transactions per day in production already!

What our QPP clients are saying about IMS 13

7

“The…IMS 13 migrations have been really easy to implement and have run very

smoothly. I have been really impressed by the ease of installing the new version and

shipping it to our systems.…..A big ‘well done’ to your team."

– United Kingdom-based Bank

“The control region CPU was reduced about 7% per

transaction.

The time waiting for the IMS log latch was reduced 90% per

transaction.

The number of WADS I/Os per transaction dropped 14%.”

“TI was able to get IMS 13 installed across all of our test and

development environments during QPP….This is the fastest we’ve

ever installed a new IMS post GA.”


One of QPP customers

Wolfgang Sicking IMS Sysprog @GAD 30+ years

IMS experience 30+, started with IMS 1.2

(IMS QPPs e.g. XRF, Shared Queues, etc.)


GAD eG:The coorporative IT-provider

GAD eG

� IT service provider, software development company and data

processing center for– approx. 430 Volksbanken, Raiffeisenbanken and retail banks in German-

speaking areas

– central banks (WGZ BANK, DZ BANK), cooperative companies

� is one of the leading specialists for banking applications.

� belongs to the coorporative banks.

� has about 50 years of experience in the banking area.

� has about 1,700 employees and is therefore one of the most

important employers in Münster.


� GAD ran many QPPs in the past in different areas

– Hardware, MVS, VTAM, NetView, z/OS, DB2, IMS

– First IMS QPP at GAD was IMS 2.1 introducing XRF

• Real intensive testing of XRF running real production like workload with

TPNS

� GAD participated in almost all IMS QPPs

– Only skipped IMS 4.1 and IMS V10

� In the past 3 IMS releases all systems (development and production) migrated

before GA

� In 2013 GAD ran IMS V13, DB2 V11, and z/OS 2.1 QPPs in parallel

QPP History at GAD


� IMS system enhancements

– Reduced total cost of ownership enhancement

• Log Latch Contention Reduction

• DB Space Management Block Serialization Latch (BLSER)

• IMS Connect / OTMA Enhancements

� Functions tested explicitely

– IMS Connect Enhancements

� Tools tested

– IBM Database Tools HPU, HPC, LIU (Fast ACBGEN)

– IMS Enterprise Suite 2.2 SOAP Gateway

– BMC Tools MAXM Reorg/EP, Pointer Checker, MainView

IMS V13 QPP


IMS V13 QPP


� Successful QPP– All milestone dates could be met

– Production migration completed by the end of September 2013

– End-of-quarter processing (end of September)• 30 Sep. 96 mio. transactions processed• 1 Oct. 97 mio. transaction processed

– End-of-year processing 2013• More than 100 mio. transaction processed on 2 January 2014

IMS V13 QPP Conclusion


� Take advantage of new technology at a very early stage

� During QPP customer works very closely with IMS development– Bi-weekly status calls– Defects are worked on with high priority– Maintenance delivered on a regular basis

� Being able to have some influence on product developments

� Very good education class in SVL and Hursley

WHAT DOES AN IBM SENIOR VICE PRESIDENT (and prior IMS Director)THINK OF 100K?

19


IMS 13 Fast Path Scalability

� Using an IMS Fast Path

based workload IMS 13

demonstrates– Higher efficiency (ITR)

– Reduced contention

– Greater Scalability

in CPU service time per transaction across a range of transaction rates

14-28% Reduction

ITR (Internal Throughput Rate) = actual transaction rate divided by CPU % utilization


IMS 13 Scalability Achieved Through Performance Improvements*

Log Latch Contention

BMP Latch Contention

IMS Connect/OTMA

IMS UDB Driver Type-2

zIIP Offload

Focus Areas Measured Improvements

66-88% contention reduction

50% elapsed time reduction

164% ETR improvement

18-62% CPU reduction

4-22% GP reduction

Sample Benefits

7.6% ETR improvement7.6% ETR improvement 10.8% ETR improvement10.8% ETR improvement24% ETR improvement24% ETR improvement

Fast Path Workload

Full Function w/ HALDB Workload

CICS-IMS DBCTL Workload

ETR (External Throughput Rate): total transaction per elapse time


IMS Database Value Unit Edition 13 (and 12)

� IMS Data Sharing clients can grow workload without impacting operational expense

� Net new applications access IMS Open Database for Java or SQL workloads

� Develop mobile applications using critical enterprise data stored in IMS

� Additional zIIP offload cost savings for Java

� Opportunities for new customers to take advantage of this Industry-leading high performance DBMS

Future Directions

� Enhance/Extend the capabilities of IMS TM with DB2

– Performance & TCO – ESAF enhancements–New capabilities

• For example: Large attachments with DB2 BLOB for immutable picture/image files, signatures, and documents, etc.

� Continued modernization of the IMS System

–Continue enhancing integration & modernization• Cloud, Mobile, and Internet integration with IMS

– Security context propagation for enhanced auditability in a distributed environment–Continue to provide analytics for IMS–Continue to provide graphical tooling to develop, deploy and manage both IMS and its

applications in support of IBM's "One UI Strategy“–Continue dynamic capabilities & eliminate planned outages

• Planned outage reduction–Cloud provisioning enablement with IMS

• Agile development, deployment, and packaging models–Aggressively pursue full integration with strategic portfolio offerings

� Parallel scheduling in IMS

� Dynamic database


IMS Planned Outage Reduction Strategy

�Remove planned outages that have a noticeable impact to the end user. (i.e. our customer’s clients)–Remove requirements to restart IMS–Remove requirements to stop DBs–Remove requirements to stop transactions/programs

�Focus on most significant impacts–Not all causes need to be removed–Customer feedback helps prioritize

•Lack of dynamic DB changes clearly highest priority•Focus in roadmap are the top causes from customers

�Focus on infrastructure to facilitate dynamic changes –Removal of SYSGEN–Load from Catalog

�Reduce IMS Shutdown/Restart time for when it is required

“…every subject was successfully covered by the most appropriate expert. While I was there at SVL, the program was flexible enough so we could address certain topics which I personally identified, that would benefit me at my home location...”

� Sessions include: Installation, HALDB features, OTMA and IMS

Connect, application topics, and MORE!

� Formal and informal classes taught by IMS engineers

� Helps you quickly grow IMS skills

� Should have at least 2-3 years of IMS experience
