4 In this open beta Java EE 7, now in CICS! Parallel services with async calls Provision CICS microservices in minutes And a lot more! ibm.biz/cics54openbeta

5 Open Beta Requirements The hardware and software prerequisites are as follows: The minimum required level of operating system is z/os V2.1. The minimum required hardware prerequisite is z Systems z10 or subsequent 64-bit z/architecture processors. The minimum required level of Java is IBM 64-bit SDK for z/os, Java Technology Edition, V7.0 SR1.

6 Java EE 7 and beyond Integrated Java EE 7 web profile Enables the integration for modern Java web applications with CICS units-of-work, security, management, and APIs Java EE 7 full platform as standard Liberty Java EE 7 Full Platform is now supported via a new standard mode using Java EE transactions, security, and APIs Allows developers to exploit JEE Full Platform capabilities whilst remaining in the easily managed CICS address space ibm.biz/cicsjavaee7

7 Java EE 7 and beyond Enhanced DB2 Support Access CICS DB2CONNs from JPA 2.0 and Session Database features, not just JDBC New IBM MQ access Connect to MQ using JMS in Liberty JVM servers Develop for CICS remotely through JCA Rapidly prototype and test applications using JCA on a local workstation with the new remote JCA Liberty feature

8 Java EE 7 and beyond Increased ziip offload in Liberty Benefit from over 90% ziip offload eligibility 90% in CICS Liberty JVM servers (ibm.biz/cicswlpziip) Updated Java New Java 8 supports adds a whole host of language features, including lambda expressions and improved type checking Connect to z/os enterprise systems With additional support in CICS, you can now use z/os Connect Enterprise Edition natively

9 Simple async services Access services in parallel Minimise idle time waiting for responses when calling services through a new CICS API for issuing parallel requests Issue and manage requests using simple yet powerful EXEC CICS commands Open samples Find great samples on the CICSDev GitHub supported with detailed articles on the CICS developer centre

10 Simple async services Using EXEC CICS RUN TRANID and EXEC CICS FETCH, external services can be called without delay FETCH can be used in any order, allowing faster services to be processed first Bridges the gap between START and LINK

11 Simple async services >>-RUN--TRANSID(name) > >--CHILD(token) >< '-CHANNEL(name)-' >>-FETCH---CHILD(token) > '-CHANNEL(name)-' >--COMPSTATUS(cvda) >< '-ABCODE(code)--'

12 Simple async services Track transactions through asynchronous calls Follow asynchronous requests through regions with enhancements to the previous transaction SMF records The new previous transaction field, combined with existing fields of previous transaction hop count and previous task ID complete the ability to trace calls Monitor the performance of async calls New SMF counters and timers collect data for running and completed Tasks.

19 Provision CICS in minutes Configuring the microservice The provisioned image is controlled by a special file, the Cicsptfile, which works similar to how a Dockerfile works Unlike Docker, nothing is virtualised in a separate container, but is mounted on USS Images can inherit other images, using the FROM statement e.g. FROM cics_liberty would inherit a CICS-supplied image which provisions a CICS Liberty JVM server.

20 Provision CICS in minutes Example Cicsptfile: FROM cics_liberty # Copy the application configuration COPY imageapps.xml ${LIBERTY_DIR}/imageApps.xml # Copy the application COPY myapp.war ${LIBERTY_DIR}/apps/myapp.war

Improved MQ in CICS MQ TRUE on Key 8 TCBs Benefit from better performance with by staying on a T8 TCB in Java programs using MQ base classes and JMS

21 Improved MQ in CICS MQ TRUE on Key 8 TCBs Benefit from better performance with by staying on a T8 TCB in Java programs using MQ base classes and JMS Start/stop facilities for MQ applications Control MQ triggering with the new MQMONITOR resource No more manual steps when the MQ connection restarts

22 Java Free JSON End-to-end non-java JSON Natively transform JSON to language structures (and vice versa) with extensions to EXEC CICS TRANSFORM DATATOJSON and JSONTODATA Shipped in V5.3 APAR PI54841 Free JSON webservices from Java with the native pipeline terminal handler DFHPIJT Shipped in V5.3 APAR PI56897 Completely removes the need for a JVM server when using CICS webservices

23 Java Free JSON Example pipeline.xml configuration: <?xml version="1.0" encoding="ebcdic-cp-us"?> <provider_pipeline xmlns=" <service> <terminal_handler> <handler> <program>dfhpijt</program> <handler_parameter_list /> </handler> </terminal_handler> </service> </provider_pipeline>

24 Safer Debugging Read only debugging transactions CEDF and CEDX are considered harmful due to a risk of accidental or malicious changes made to storage during program execution New read-only versions of these transactions (CEDG and CEDY) are provided to mitigate these concerns

25 EXCI Channels External CICS Interface (EXCI) Pass more data from z/os programs to CICS with support for channels and containers APIs in EXCI APIs supported: UT, GET, MOVE and DELETE CONTAINER DELETE CHANNEL Not only does this remove the 32K limit of a COMMAREA, these Channels and Containers also support code page conversion A Channel can be specified on both the EXEC API and the call level API

26 And more! New event format for CICS events Emit CICS events in the Decision Server Insights Events (DSIE) format for use with ODM Decision Server Insights Shipped in V5.3 APAR PI55134 Shipped in V5.2 and V5.1 APAR PI55133 Process z13 vector registers in LE Exploit SIMD in C/C++, COBOL, PL/1 and JVM language features Requires LE APAR PI53833 Shipped in V5.3 APAR PI59322

27 Beyond the beta Taking Java further (continuous delivery!) Harness the full power of Java EE 7 with CICS; features, including batch processing, will be able to access DB2 in bindings mode, run CICS API commands and integrate with CICS transactions Take Java EE outside of the web container, with Link to Liberty you can call applications running in a Liberty JVM server as CICS programs

28 Beyond the beta Early access CICS Designed Partnership and Business partner program, actively participate in ideas and proposals CICS betas to learn about and access the latest functionality even earlier CICS open betas, which come with documentation and CICSDev articles Feedback Your feedback is important to us!
