Impact for JVM memory management change from Java 7 to Java 8
The memory management has been changed from Java 8 - permanent generation space has gone from heap and metaspace in native memory is introduced.
- Does this change impact on the JVM configuration (in this article)? (We may need to replace -XX:PermSize, -XX:MaxPermSize by -XX:MetaspaceSize, -XX:MaxMetaspaceSize. Anything else to consider?)
- We had done H/W sizing. The sizing sheet doesn't require to input JDK version. Is that mean this change is not impact on memory estimates in H/W sizing?

Thank you for the answer.
Hi,
Permgen is replaced with metaspace in Java 8. This change does not have impact on JVM and H/W sizing.
