So Why Do Mainframes Still Matter

• gt 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

• The worlds top 25 banks.
• 23 of the top US retailers.
• 9 out of 10 of the worlds largest insurance
  companies run DB2 for z/Series

4
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

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

7
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• Documentation out of date, missing,

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
IBM introduces new architectural features -
specialty engines -

• Strategic new mainframe innovation

• Improves mainframe viability

IFL (Linux)

• Addresses competitive threats

zAAP (Java)
zIIP (database)
New innovation
Shadow uniquely exploits zIIP/zAAP specialty
engines
Significant performance enhancements for
SOA Dramatic improvement in mainframe TCO
22
IBM Exploitation of zIIP Specialty Engine

• IBMs 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

High Utilization of General Purpose Processor
Reduced Utilization of General Purpose Processor
23
Exploiting zIIP for Enhanced SOA Performance

• Next generation middleware exploits zIIP for SOA
  related workloads
• Dramatic improvement in SOA performance and TCO

SOAP/XML Processing Results in High Utilization
of GPP
Middleware Request Offload to zIIP Low
Utilization of GPP
24
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

25
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

26
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

Benefits zIIP/zAAP Exploitation

• Improved performance
• SRBs 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

29
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

Impact of Shadows Exploitation
Original Upgrade
Deferred Upgrade

• This scenario depicts
• 20 ACGR in MSU Consumption (sited by IBM as
  average rate)
• Shadows zIIP/zAAP processing reduces GPP
  workload
• Shadows usage of the zIIP helps defer the
  upgrade

32
Shadow in a Nutshell

• Single Unified Architecture
• Reduces complexity and increases reuse
• Non-invasive
• Maximise value from existing systems and skill
  sets
• z/OS Applications becomes a full SOA participant
• Standards-based, zero-latency technologies
• Maximizes both the zIIP and zAAP specialty
  engines resulting in unprecedented MSU savings
