How do I increase the memory for the Java Virtual Machine?
SQL Developer - FAQUsually the default memory configuration of your VM should be sufficient to work with SQL Developer. If you want to increase the available memoy anyway you will have to start the application with additional command line options. If you use a Sun Microsystem Java VM open a shell window, change to the SQL Developer folder and type java -Xmx256m -jar sqldeveloper.jar to start with a maximum heap memory of 256 MB. The default maximum heap size is 64 MB.
Related QuestionsWhat is Virtual Memory?
Environment settings set by a batch file are not working.Virtual Memory makes up for the lack of RAM in computers by using space on the hard disk as memory, Virtual Memory. When the actual RAM fills up (actually its before the RAM fills) then virtual memory is created on the hard disk. When physical memory runs out, the Virtual Memory Manager chooses sections of memory that have not been recently used and are of low priority and writes them to the swap file.

Will adding more memory increase "virtual memory"?
SpecTek Select - WelcomeNo. RAM and virtual memory are not the same. Virtual memory allows you to use a portion of your hard drive as though it were RAM. Because your hard drive is up to 100 times slower than your RAM, virtual memory is much slower than RAM. When you upgrade your RAM, you may discover that you use your virtual memory less because you will now have more memory available to complete the tasks that were previously handled by your virtual memory.
Related QuestionsWhat Java virtual machine (JVM) do I use to run the AspectJ compiler?
AspectJ Frequently Asked QuestionsUse the latest, greatest, fastest JVM you can get your hands on for your platform. The compiler's performance is dependent on the performance of the JVM it is running on, so the faster a JVM you can find to run it on, the shorter your compile times will be. At a minimum you need to use a Java 2 or later JVM to run the compiler (J2SE 1.3 for AspectJ 1.1). We realize that this constraint can be a problem for users who don't currently have a Java 2 JVM available.

Related QuestionsShould I increase my virtual memory pool for Opennap?
Opennap NG 0.49 @ SF - FAQNot for Opennap! Virtual memory works by moving parts of the allocated RAM which are considered "not being used at the moment" by the OS to disk. For instance, if you have a paint program with 5 pictures open, usually 4 of them should be considered "not being used at the moment" while you are working on one of them, hence be worthy objects for being swapped out to disk.

HANDLE.NET FAQsIf you get an out-of-memory error (or would like to increase the amount of memory that the server can use), add the "-mx128m" argument when running java/jre. In fact, we recommend increasing the amount of memory available to Java to allow Java and the server to use up to 128 megabytes of virtual memory, if necessary. Alternatively, the config.dct file can be edited to cut down on the amount of memory used by changing the number of threads allocated for each listener.

Related QuestionsWhy not Factor for the Java Virtual Machine or .NET?
Frequently asked questionsOriginally, Factor was written in Java, and there was a compiler to JVM bytecode. But, to improve speed and the foreign function interface, Factor was rewritten in C and Factor. JFactor was abandoned in favor of CFactor. At this point, basicaly no Factor code would work in the old JFactor unmodified, as JFactor is missing several key features like generic words and syntax extension. Factor is currently natively compiled, not bytecode compiled.
Related QuestionsCan I run a Java virtual machine in an IPm controller?
SIXNET - Leading the way in Industrial Ethernet, Modems, LIN...No, you cannot. Java requires a huge amount of memory and considerable processing horsepower to run. Here is our advice: One of the things that makes Java so big is its support for graphics. If you need graphics in your application, the IPm is not suited for your application (since it is a blind node). If you don't need graphics, we suggest porting your application to efficient and highly portable C code. We have been told that Java is not as portable as Sun Microsystems would have you believe.

Code Style: Java language frequently asked questions (FAQ)There is no direct management of the storage size of code that is held in memory by the Java Virtual Machine (JVM). The virtual machine manages the allocation and de-allocation of storage through an integral garbage collection system.
