3. 3 2012 IBM Corporation Agenda The CICS Java Web Container based on WAS Liberty technology What is a Hybrid Application anyway and why would I want one? Options for Hybrid Applications and when to use them Nought to Web App

4. 4 2012 IBM Corporation Introduction to the JVM Server & CICS use of the Liberty Profile

5. 5 JVM Server Architecture CICS TS V4 JVM LE enclave CICS Task PThread JVM thread CICS Task PThread JVM thread CICS Task PThread JVM thread Can attach multiple pthreads/CICS tasks to the JVM at the same time Therefore serve more requests using a single JVM Result is increased tasks per region up to 256 programs simultaneously on T8 TCBs For 3rd party JVM technology (CICS TS V4.1) and user programs (CICS TS V4.2) Heap & Classes An alternative to pooled JVMs, not a replacement (yet) JCICS API JVM thread JVM thread JVM thread JVM thread

6. 7 2012 IBM Corporation Configuration by Exception This is the entire configuration needed to run Liberty as a Web-container with Servlet support.

7. Convergence Of features, fix packs and timing

8. 10 2012 IBM Corporation What is a Hybrid Application anyway and why would I want one?

9. Liberty in CICS a Hybrid Runtime What do you see, CICS or Liberty? ...It's all a matter of perspective

10. 05/22/1412 2012 IBM Corporation Hybrid Threads JVM task T8 TCB Worker thread attach change-mode attachCurrentThread LE enclave CICS Task Same Task Context JDBC Link to COBOL Etc. Liberty Web Feature (CICS)ExecutorService.execute (Runnable) HttpListener Thread Dispatcher (task generator) XMATURIMAP

11. 13 2012 IBM Corporation Each 'Invocation' (think Servlet Request) on a Hybrid Thread is also a CICS Transaction (Has a Tranid, Task Context etc). This gives you A single common Transaction (UOW) and CICS Managed JDBC Which can cross between Java and Cobol Full JCICS API Access In particular, LINK and access to VSAM WLM (CICS WLM, Performance Classes etc). Monitoring / Statistics CICS Transaction Tracking / Association Data Benefits of Hybrid Threads

12. 14 2012 IBM Corporation Options for Hybrid Applications and when to use them

13. Presentation Complex Services Simple As CICS has got smarter, the level of complexity has increased. CICS TS V5 will continue to deliver more advanced capabilities. Hybrid Applications can both be about presentation logic and services, as well as Java or PHP When to use what and customer use cases a vision for an easier to use application server 15 Presentation Servlet JAX-RSJAX-WS Dynamic Scripting JSP JSF

14. CICS Dynamic Scripting Java EE / CICS Traditional Liberty CICS Dynamic Scripting StrategicValue,Cost,Complexity,Usage Number of applications Time to value is more important than enduring value Strategic, long- lived applications Enterprise Applications Team/Project Applications Personal Applications Creating reports, dashboards and widgets Quickly front ending existing applications Exposing CICS assets in mash-ups Creating productivity applications Quickly trying out new business ideas Introducing new IT staff to CICS via PHP Developing without a dedicated budget Porting existing unmanaged PHP into CICS Departmental Applications Can be used to develop and deploy lightweight, fit for purpose, situational applications that meet departmental, team, project and personal requirements, e.g.:

16. PHP In Action PHP code in Sample

17. 19 2012 IBM Corporation Nought to Web-App

18. 20 2012 IBM Corporation 1) Create a JVM server resource in Explorer, CEDA, or CPSM.

19. 21 2012 IBM Corporation 2) Configure the JVMProfile - Copy the sample DFHWLP - Check JAVA_HOME is correct. - Ensure Auto Configure option is set to true for first time - Point your JVM server definition at the new JVMProfile

20. 22 2012 IBM Corporation 3) Enable the JVM server

21. 23 2012 IBM Corporation 4) Liberty is running! (check the logs). Server defaultServer created. Launching defaultServer (wlp-1.0.0.20120428-1251/websphere-kernel_1.0.0) on IBM J9 VM, version pmz6470sr1- 20120302_01 (SR1) (en_US) [AUDIT ] CWWKE0001I: The server defaultServer has been launched. [AUDIT ] CWWKG0028A: Processing included configuration resource: file:/u/ivanh/IYK3ZIH1/LIBERTY1/wlp/usr/servers/defaultServer/installedApps.xml [AUDIT ] CWWKG0028A: Processing included configuration resource: file:/u/ivanh/IYK3ZIH1/LIBERTY1/wlp/usr/servers/defaultServer/cicsSecurity.xml [AUDIT ] CWWKZ0058I: Monitoring dropins for applications. [AUDIT ] CWWKF0011I: The server defaultServer is ready to run a smarter planet.

22. 24 2012 IBM Corporation 5) Install Eclipse 3.6.2 - preferably JEE version, but Classic will suffice. http://www.eclipse.org/downloads/packages/release/helios/sr2

23. 25 2012 IBM Corporation 6) Install IBM CICS SDK for WebSphere Application Server Liberty profile v5.1

24. 26 2012 IBM Corporation 7) Create a Dynamic Web Project, or choose one of the Examples

25. 27 2012 IBM Corporation 8) Export the CICS bundle project

26. 28 2012 IBM Corporation 9) Pick a zFS location for the CICS bundle project

27. 29 2012 IBM Corporation 10) Create a CICS bundle definition to control the life-cycle of the Application

28. 30 2012 IBM Corporation 11) Install the CICS bundle definition

29. 31 2012 IBM Corporation 12) Run the application! [AUDIT ] CWWKT0016I: Web application available (default_host): http://winmvs2c.hursley.ibm.com:27245/com.ibm.cics.server.example.wlp.tsq.web/

30. 32 2012 IBM Corporation zFS zOS App App App CICS Liberty JVM server Deploy Eclipse with Liberty Tools Use CICS Resources Enable Putting it all together

31. 33 2012 IBM Corporation Summary and Future

32. 34 2012 IBM Corporation Summary of Key Benefits Local. Lightweight. Fast. Web Applications run locally in CICS with direct access to CICS data and resources. No adapters, no converters, same address space. Standard tools for developers. Familiar, industry standard tools with Eclipse and Dynamic Web Projects. CICS Explorer SDK enhances the deployment experience. Portable. Presentation logic in Servlets, business logic in OSGi bundles. Servlets are portable across runtimes. Bundles provide componentization. Modular design. Architected in a modular way using OSGi, the server only enables and starts the features required by the applications and configuration. If you're not using a feature, it won't start in your server runtime Dynamic runtime. Features can be added to the server dynamically, using the OSGi framework, while the server is running, with zero downtime and server restarts. Similarly server and application config can be updated without the need to restart. Eclipse based tools. The eclipse tools for the Liberty Profile are small and very well integrated with the Liberty Profile environment
