Free Module 1: Java Performance Masterclass | Instructor - Ram Lakshmanan

In this module, you will learn about Java memory management & different memory regions: Young Gen, Old Gen, Metaspace, and Native Memory. The module includes an engaging animated demonstration of how the JVM executes a sample Java program, providing a better understanding of how the JVM operates when executing your applications. The module also covers the difference between stack and heap memory, including what types of data are stored in each.
By the end of this module, you will have a solid grasp of the essential concepts related to the JVM's inner workings.

Does -XX:MaxMetaspaceSize also workable for IBM WebSphere Open J9 JVM.

[@prithiekammai9186]

As I know, the -XX:MaxMetaspaceSize flag is specific to Oracle's HotSpot JVM and is not typically applicable to other Java Virtual Machine implementations, such as IBM WebSphere Open J9 JVM. For IBM WebSphere Open J9 JVM, you typically manage metaspace settings using different flags or configurations specific to that JVM. IBM provides its own set of flags and configuration options for tuning the JVM, including metaspace settings. You should consult the documentation specific to the version of WebSphere you are using for guidance on how to configure metaspace settings. If you're working with the WebSphere Open J9 JVM and need to manage metaspace, refer to the IBM documentation or contact IBM support for the most accurate and up-to-date information on configuring metaspace settings.

@@prithiekammai9186 I tried alot to find. IBM WebSphere and eclipse Open J9 JVM argument doesn't contain for MetaSpace. If anyone have idea let me know.
