SOA Leading To Mainframe Resurgence
• SOA is altering the perception and role of the
mainframe
• Firming up of industry standards has allowed
developers to use existing skills/tools
• Initially data connectivity - ODBC/JDBC
• Web Services/SOA – XML, SOAP, WS -*
• Ability to re-combine and re-use within SOA
more cost/time efficient than migration
• Mainframe now more of an
industry standard server, full
participant in SOA
• Wrap and reuse rather than rip
and replace

Data as a Service
From SOAP to BPEL
From SQL to SOAP

9.
Maintaining Mainframe Quality of Service
• Data and transactional integrity are essential
• Fundamental to SOA
are layers of
abstraction
• Diagnostics challenge
increases with addition
of legacy services
• Enterprise class
management needed
for integration

10.
SOA and Mainframe Security Management
• Each logon (RACROUTE)
consumes 6 ms
• 1 million web service
invocations per day
• 11 transactions per
second
• 1.6 CPU hours savings
per day
• 50 CPU hours per month
(greater than 2 days)
• Typical SOM savings >
99%

11.
Shadow – Core Functionality
• Industry’s only single, unified platform for mainframe
integration
• SOA – Web services and Real-time events
• Data – SQL and Real-time events
• Presentation enablement – HTML, Components
• Multi-threaded, mainframe address space
• Multi-tasking and multi-threaded
• Maintains mainframe QofS – performance, scalability, security
• Manageability
• Instrumentation Server
• Sysplex Trace/Browse
• Auditable / Charge back
• Exploitation of sophisticated z/OS features
• Workload Manager
• Security Authentication (SOM)
• Coupling Facility (XCF)
• Offload work to the zIIP

12.
Solving The Mainframe TCO Problem
• Hardware costs and MSU upgrades are not the main problem
• Upgrades trigger a cascade of software cost increases from
ISVs that weigh down mainframe TCO
• Certain types of workloads could be more effectively handled
outside of General Purpose Processor (GPP)
• Processing Java on mainframe not MSU friendly
• Large ERP or BI related data queries drain performance (i.e. DB2)
• Enter the new IBM specialty engines (IFL, zAAP, zIIP)
• Run un-measured
• Not speed restricted
• Workloads on specialty engines do not count against MSUs
assigned to the GPP

Next generation mainframe middleware that
uniquely exploits zIIP/zAAP specialty engines
Significant performance enhancements for SOA
Dramatic improvement in mainframe TCO

IBM Exploitation of zIIP Specialty Engine
• 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

Not All Middleware Is Created Equal
• Mainframe middleware
deployments vary
• distributed runtime
• mainframe based server
• Most mainframe
middleware is TCB based,
incapable of accessing
zIIP specialty engine
• Middleware exploitation
of specialty engines
requires “genetic”
alteration to threads
• Ability to run in SRB/TCB
mode essential
• Licensed technology

17.
Which Shadow Features Exploit zIIP?
• Shadow Foundation
• Shadow Networking & TCP/IP Communications layer
• Shadow Instrumentation Server (Logging & Tracing)
• SOAP and XML Processing/Parsing
• Shadow Internal Messaging Shadow XA support
Shadow’s Scripting Language
• Security Optimization & Mgmt. (SOM)
• Shadows ODBC & JDBC processing
• Shadow Event Facility (SEF)
• Shadows SQL Engine

Exploiting zAAP for Optimizing BPM
• zAAP exploitation enables the mainframe to
effectively handle Java workloads and participate in
BPM initiatives
• Java is primary platform for running industry-standard BPEL
2.0 (Business Process Execution Language)
• BPEL can provide top-down, process oriented
approach for orchestrating mainframe Web services
• Processing intensive BPEL runs within zAAP
• Lower TCO - not counted against GPP
• Improved performance - not speed restricted
• Run BPEL workflows composed of platform
independent, heterogeneous Web services, with
better performance and lower cost
