  • S107 - Don't Let Java Out of Memory Error Get Your CICS Down

    CICS Sessions: Room K second floor

    Session Evaluation

    Java has become the programming language of choice for application modernisation on z/OS, but deploying these new apps 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. This session will explain how the JVM allocates & manages the MVS storage it needs & show you how to ensure JVMs can be managed & monitored in both CICS & batch environments, using the latest JVM tools, CICS facilities & traditional MVS dumps & IPCS. Leaving you with the confidence that you need to manage Java apps anywhere on z/OS.
