LegaSuite: Leveraging CICS TS V4.2


LegaSuite and CICS

• Expose and reuse business logic as SOA

• Improve integration

Share and reuse

business logic

• User- and web-friendly reports, dashboards, charts, and graphs on demand

Improve business insight

• User- and web-friendly applications

• Improve business processes

Improve user experience

LegaSuite: Exploiting CICS 4.2 Java Enhancements

13


CICS Java Applications: Getting Started

� CICS Explorer SDK

� JCICS class libraries

� Eclipse IDE, CICS Explorer and the CICS Explorer SDK

� Install the SDK into an Eclipse IDE

� Setup, Deploy and Test the JCICS examples

� Define/Install CICS resources

� JVMServer, Transaction, Program and Bundle definitions

� Setup CICS region

� SIT JVMPROFILE

� Java 6.0.1

� Publish the examples and test

14


CICS JVM Servers

� JVM Profiles in JVMPROFILEDIR (HFS)

� Threadlimit (Max T8 threads in a JVMServer)

� Controled by SIT value MAXTHRDTCBS

� Maximum T8 TCBs=1024

� Maximum per JVM Server is 256

� No limit on JVM Servers per region

15


CICS Java: Additional Considerations

� OSGi

� Use SDK for new or re-packaging

� Must know the name of the JVMSERVER

� Review best practices

� Housekeeping, Threadsafe!

� JZOS copybook importers

� Java Health Center (Free)

� http://www.ibm.com/developerworks/java/jdk/tools/healthcenter/

SOA and CICS Today

17


SOA Workload before 4.2

� Non-CICS abstraction layer introduces another layer of

complexity

� More hardware than ‘point to point’

� Single point of failure

� Increased latency (network and extra stack in architecture)

� Configuration, management, operational considerations

� zAAP enabled JVM Pool not as scalable and efficient

as the zAAP enabled multithreaded 64-bit JVM Server

� CICS performance is stellar, how can we reduce cost?

18

Innovate with Java in CICS 4.264-bit performance at the cost of zAAP


LegaSuite: More Workload, Much Lower Cost

� Performance of 64-bit multithreaded JVM Server at the zAAP cost!

� Message Transformation

� Service Routing

� Robust Integration

� Service Flows

� CICS Channel/COMMAREA, Screen based and dB


Why more workload in CICS?

� Lower hosting cost, closely-coupled with CICS

� Management, Monitoring, Infrastructure, Security

� Improved interaction, proximity to CICS apps

� Highly redundant

� Fewer ‘hops’, ‘point to point’ performance

� Leverage System z investment

� 64-bit technology (huge capacity)

� zAAP processors (lower cost)

� High volume transaction processing for Java apps

� Federated/Multiple/Hybrid ESB’s are common
