Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. It is a general-purpose programming language intended to let programmers write once, run anywhere ( WORA), meaning that compiled Java code can run on all platforms that support Java without the need to recompile. Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible.

Consider setting Xms and Xmx to the same value, as this can decrease the time GC takes to occur, as it will not attempt to resize the heap down on each collection./ 20 September 2022 23 days ago ( 20 September 2022).In a simplistic explanation, PermGen is used to store classes, and is generally quite static in size, and has been removed in Java 8. If your error does not reference PermGen, there is no need to increase it.OutOfMemoryError : PermGen space, increase the -XX:MaxPermSize parameter in 256mb increments until the error stops occurring. This is because increasing the heap beyond the capabilities of your server to adequately Garbage Collect can cause other problems (eg performance/freezing) Increase Xmx in small increments (eg 512mb at a time), until you no longer experience the OutOfMemory error.If you do decide to increase the memory settings, there are a few general guidelines to follow: In case you need advice regarding how much memory you should use please check this page for some examples of hardware specifications.
