Don't Let Java Out of Memory Error Get Your CICS Down

Project and Program: Application Architecture Development and Integration, CICS

Tags: Proceedings, 2020, SHARE Fort Worth 2020

Java has rapidly become the programming languages of choice for application modernisation on z/OS, but deploying these new applications onto the platform can require a new understanding of how to manage the subsystems within which JVMs are deployed. Not understanding the memory utilisation of Java applications could bring your modernisation dreams to a sticky end.

Fear Not!  as this session will explain how the Java Virtual Machine (JVM) allocates and manages the MVS storage it needs and show you how to ensure JVMs can be managed and monitored in a both a CICS and batch environment, using a combination of the latest JVM tools, CICS facilities and traditional MVS dumps and IPCS.  Leaving you with the confidence that you need to manage Java applications not just in CICS but anywhere on z/OS and realise your modernisation dreams.-Phil Wakelin-IBM UK Laboratories Limited
