2 Agenda Who s here? HostBridge Background What you need to know to understand why we did what we did (and why we think it s pretty cool!) ziip Enablement ziip realities CICS realities HostBridge realities CICS + HB + ziip = Wow!

3 We Like to Listen A few questions first Do you know whether your System z has a ziip? Of those, how many DO have a ziip? How many ziips do you have? What workloads are currently exploiting ziip? How many plan to exploit ziip? Anyone using ziip for the purpose of application integration or SOA enablement?

4 Who Is HostBridge Technology? CICS integration software company Founded in 2000 Pioneered CICS integration using XML US, Canadian and EU Patents Serving large organizations Experian, Fidelity Investments, Clarke American, PACCAR, State of Arizona, Lockheed-Martin, NYCDOE, Navy Federal Credit Union, NISSAN IBM and CA Technology Partner Ready for SOA, Ready for Tivoli, Ready for Rational, CA Smart Certified: CA Ideal, CA ADS, CA Gener/OL, CA Telon Application Generator

5 In other words We re sort of like civil engineers, who use software to build bridges for System z apps.

6 Modernization Approaches SOA Enable / Integrate Reuse / Enhance in Place Re-Architect Modernization Re-Host Replace Migrate

7 Our DNA Focus on customer s priorities Every feature reflects customer collaboration Leverage CICS apps using industry standards High-Fidelity integration Leverage intellectual property (US and EU Patents) Integration without screen scraping Obsess about performance and reliability Let System z and CICS do more and do it better Every microsecond counts CICS, CICS, CICS Innovate and do the hard stuff CICS

13 System z Specialty Engines What are they? Specialty engines are processors that can help users expand the use of the mainframe for new workloads, while helping to lower cost of ownership. Types IFL - Linux workload zaap Java workload ziip DB2 and other eligible workloads Value Proposition Shift MIPS to less expensive (and possibly faster) engines Reduce software costs related to GP capacity (IBM and ISVs) Delay/Avoid GP capacity upgrades Significant potential performance improvements

14 ziip Eligible Workloads Eligible workloads include portions of the following: DB2 for z/os V8, DB2 9 and DB2 X for z/os z/os Communications Server z/os XML System Services z/os Global Mirror z/os Communications Server z/os CIM Server IBM also licenses ISV s to make their workloads ziip eligible. HostBridge workload is ziip eligible!

15 ziip Facts of Life All workload must run as an Enclave SRB Enclave SRBs are preemptable, and can be run at a lower major dispatching priority than tasks in the same address space. The rules for SRB s still apply Can obtain, reference, use, and free storage areas, but the areas must be owned by a TCB Cannot issue SVCs except ABEND WLM Enclaves have a few implications Interaction with WLM Execution Delay Services What an ISV can/cannot ziip enable is governed by a license agreement with IBM

16 Integration Workloads Integration workloads, in general, are different They involve orchestration of other application and data assets They involve customer-written orchestration scripts, instructions or specifications Some aspects are CPU intensive - others not Implications What you can/cannot do under an SRB is important Processor switching must be understood and optimized

17 So Let s Run a Test Intended to assess the physics of processor switching (max. switch rate on a particular system in 1 second) Two factors were varied: whether the SRB was running on a ziip or GP whether the TCB released the PET directly (via IEAVRLS) or indirectly (via XM service that issues IEAVRLS)

18 Test Results Wait/Post/Pause/Release/Time storm between TCB and SRB SRB on GP Test (Direct) Test 1 220,301 Test 2 225,916 Test 3 229,890 Averages 225,369 SRB on GP Test (Indirect) Test 1 182,663 Test 2 176,735 Test 3 165,732 Averages 175,043 Number of iterations in 1 second SRB on ziip Test (Direct) Test 1 19,016 Test 2 20,097 Test 3 20,312 Averages 19,808 SRB on ziip Test (Indirect) Test 1 17,516 Test 2 17,796 Test 3 17,475 Averages 17,596 Test results are intended to illustrate potential processor switching impact.

19 CICS Integration Workloads CICS is a melting pot of apps and data Illustrates its strengths -- and what we are up against! CICS has it s own approach for separating program logic from CICS services CICS offers a growing degree of run-time freedom Open TCBs, OPENAPI, etc. CICS still has rules, such as All EXEC CICS commands must be executed under a CICS managed TCB CICS owns its own relationship to WLM Thus CICS integration workloads have very unique characteristics!

20 Example: Auto Manufacturer Enterprise Integration Reqs: BMS non-bms non-visual - COMMAREA - Natural/Adabas - MQ - APPC Applications - DB2 - VSAM - Complex MRO - TDQs and TSQs That s a lot of stuff! Siebel CRM WebSphere ESB Customer Service Rep RESTful interface: HTTP, Query String, XML Finance Division CICS TS (Multiple Regions) Services Lease Management Application BMS Transactions No change to existing CICS apps VSAM Files First implementation ~ 40 web services in 35 man days

21 What Customers Wanted Change NOTHING (about your scripts) Change EVERYTHING (about how they run) Change TRANSPARENTLY (we handle the details)

22 The Plot Thickens By design, the HostBridge components that run on System z are written in multiple languages IBM Assembler (Low-level stuff) IBM XL C/C++ (Bulk of product functionality) IBM Enterprise COBOL (limited; management tooling) Question: How do you ziip enable a product that Is intended for high-performance integration Traditionally runs under CICS Compiled with IBM LE compilers And complies with the IBM ziip license!

23 Choices, Choices Answer: Very nicely, thank you! CICS and ziip are not antithetical But there are some important design issues First and foremost: where you do what! Second: Is one choice best for all customers or workload cases? But, we need a vocabulary to discuss how programs run in relation to CICS Under CICS code that runs inside a CICS address space and under a CICS managed TCB Inside CICS code that runs inside a CICS address space, but not under a CICS managed TCB Outside CICS code that runs in a private address space (Don t worry, we ll take care of it.)

24 Under CICS CICS TS H T T P CICS TCB HB and - indicate where more/less work occurs ( division of labor ) M Q This is the way HostBridge has always worked. If your integration requirements are super heavy on EXEC CICS calls and light on other processing, this might still be the best approach.

25 Inside CICS CICS TS HostBridge H T T P CICS TCB HB - Private SRB HB ++ Private TCB HB - With ziip support, a HostBridge address space is used to provide certain services. M Q In this configuration, the bulk of the action still happens inside the CICS address space, but runs on the ziip. All EXEC CICS commands are serviced under a CICS TCB. If your GP s are knee capped (relative to your ziips), prepare to be blown away by the performance.

26 Outside CICS CICS TS HostBridge H T T P CICS TCB HB - TCB/ SRB HB ++ In this config, WLM can play a more proactive role in managing the AE. M Q Depending on your integration requirements, the action can also happen outside the CICS address space. Until we can find a compelling reason otherwise, only EXEC CICS LINK commands will be supported in this configuration (but much more is possible).

27 Inside / Outside / Over / Under CICS TS HostBridge Other H T T P CICS TCB HB - Private SRB HB + TCB/ SRB HB + HB - Get creative! M Q Depending on your integration requirements, the division of labor can be customized for optimal performance and integration fidelity. The power of the JavaScript language with the scalability of System z. We think that s a recipe for SOA and Web integration simplicity AND power!

28 Objective Customer Scenario Transform existing CICS programs into web services with little/no performance degradation Eliminate concern that mainframe SOA enablement would be slow. Ideally, we want SOA for free. Solution Configuration Outside CICS HostBridge (under CICS) shunts SOA and integration workload to HB Engine running outside CICS Existing CICS program runs unchanged (under CICS) Result Response times using HTTP/SOA very close to existing MQ/non-SOA configuration

29 HostBridge for ziip System z Requirements z9, z10, zenterprise (and future models) z/os 1.9+ (any supported version) ziip Processor HostBridge Requirements HostBridge V6.5+ CICS TS 3.1+ Scripts run on HB v6+ Process Automation Engine ( HBJS ) Bottom Line 100% of HB Process Automation Engine runs on the ziip 100% of customer written scripts run on the ziip 0% of existing CICS apps run on the ziip (that s a good thing)

30 So what is HostBridge for ziip? Industrial strength, standards based, integration software for CICS and System z applications building on the power of ziip specialty processors in a safe and secure manner that moves your business forward, and improves your bottom line.
