• z/Services• z/Direct• z/Events• z/Presentation

Solving The Mainframe TCO Problem• zIIP• zAAP


So Why Do Mainframes Still Matter

• The world’s top 25 banks….

• 23 of the top US retailers….

• 9 out of 10 of the world’s largest insurance companies run DB2 for z/Series

> 60% of the world “system of record” data on mainframes

Over 450 of Fortune 500 rely upon mainframes More commercial transactions processed on

mainframe than any other platform


Re-capturing The Value of Legacy Assets

Vital role within enterprise

Not relics of the past, but essential working components of the present

Mainframe interoperability has evolved

Web services have emerged as the industry standard method for SOA


SOA in Action

APPLICATION SERVER

USER-DEFINED SERVICE

LEGACY APPLICATION

PROCESS SERVER

RELATIONAL DATABASE

BATCH SYSTEM

PORTAL SERVICE

Idealised world where data and process flows naturally


Mainframe Integration Complexity

Complexity = natural product of innovation and growth• More a result of change to growth than error

Factors that contribute to complexity• Disjointed legacy systems• Continued innovation• Economics – doing more with less• Mergers/Acquisitions


Mainframe Integration Complexity

Unchecked IT complexity can become a major obstacle• Constricted access to data• Increased costs to maintain• Multiple points of failure

Reduces infrastructure flexibility

Heterogeneity – even within z/OS databases and systems

Documentation – out of date, missing,


Typical Mainframe Accidental Architecture

Non-invasive development

Protects proven legacy logic

Deployment options:

• Mainframe• Windows


Shadow Unified Architecture


The IBM Mainframe Base: Alive and Kicking Published: July 10, 2007 by Timothy Prickett Morgan

Solving The Mainframe TCO Problem

Upgrades trigger a cascade of software cost Certain workloads could be more effectively handled Processing Java™ on mainframe not MSU friendly Enter the new IBM® specialty engines (IFL, zAAP,

zIIP)• Run un-measured• Not speed restricted

Workloads on specialty engines do not count


Exploiting IBM Innovation

Strategic new mainframe innovation

Shadow uniquely exploits zIIP/zAAP specialty engines

IBM introduces new architectural features - specialty engines -

Improves mainframe viability

IFL (Linux)

zIIP (database)

zAAP (Java)

Significant performance enhancements for SOA

Dramatic improvement in mainframe TCO

Addresses competitive threats

New innovation


IBM Exploitation of zIIP Specialty Engine

High Utilization of General Purpose

Processor

Reduced Utilization of

General Purpose Processor

IBM’s original focus for the zIIP was related to DB2 and support for ERP/CRM/BI data intensive workloads

Better performance and TCO associated with DB2


Exploiting zIIP for Enhanced SOA Performance

SOAP/XML Processing

Results in High Utilization of

GPP

Middleware Request Offload

to zIIP – Low Utilization of

GPP

Next generation middleware exploits zIIP for SOA related workloads

Dramatic improvement in SOA performance and TCO


Not All Middleware Is Created Equal

Mainframe middleware deployments vary • Distributed runtime• Mainframe based server

Most mainframe middleware is TCB based

Middleware exploitation of specialty engines requires “genetic” alteration to threads

Ability to run in SRB/TCB mode essential


Which Shadow Features Exploit zIIP?

• Shadow Networking & TCP/IP layer

• Shadow Instrumentation Server

• SOAP and XML Processing/Parsing

• Shadow Internal Messaging, XA support & Scripting Language

• Security Optimization & Mgmt. (SOM)

• Shadows SQL Engine, ODBC & JDBC processing

• Shadow Event Facility (SEF)

• Metadata Mapping & HTX Processing


Exploiting zAAP for Optimizing BPM

Effectively handle Java workloads & participate in BPM initiatives

BPEL provides a process oriented approach for orchestrating Web services

Processing intensive BPEL (Java/XML) runs within zAAP • Lower TCO - not counted against GPP• Improved performance - not speed restricted

Mainframe can now run BPEL workflows


Any JVM orBPEL 2.0 Runtime

Mainframe IFL

Shadow BPEL Deployments

Deployment Flexibility

zAAP exploited JVM


Benefits: zIIP/zAAP Exploitation

Improved performance• SRB’s are lighter than TCBs• zIIPs and zAAPs are not speed restricted• 30-90% reduction in middleware MSU

consumption• Faster XML/SOAP processing• Faster ODBC/JDBC processing


Benefits: zIIP/zAAP Exploitation

Lower TCO• Workloads running on zIIP or zAAP are not counted • MSU consumption of middleware will be lower• Total Mainframe MSU usage will be lower
