CICS and Java: How the JVM Server transforms Java in CICS

Project and Program: Application Architecture Development and Integration, CICS

Tags: Proceedings , SHARE in Anaheim 2012 , 2012

CICS has for a long time provided a Java environment for application development. In recent releases of CICS the JVM Server has transformed CICS into a first-class hosting environment for Java. This session will provide a brief history of the development of the Java environment within CICS, followed by a detailed look at the capabilities offered by CICS version 4. In particular we will look at how the OSGi framework provides excellent lifecycle management of Java applications without having to restart the JVM Server, how Java application can be eligible for zAAP offload thereby reducing the cost of a transaction, and how the JVM Server supports multiple concurrent transactions, reducing the storage requirements and the need for multiple JVM instances in a single region.
