How to run on 64bit VM while the native SWT are 32bit If you are running the Memory Analyzer inside your Eclipse SDK, you need to edit the eclipse.ini file.

It also contains more details if you are running on Mac OS X. The initial parse and generation of the dominator tree uses the most memory, so it can be useful to do the initial parse on a large machine, then copy the heap dump and index files to a more convenient machine for further analysis.įor more details, check out the section Running Eclipse in the Help Center. Memory Analyzer 1.3 using -Xmx58g has successfully analyzed a heap dump containing over 948 million objects. MemoryAnalyzer.exe -vmargs -Xmx4g -XX:-UseGCOverheadLimitĪlternatively, edit the MemoryAnalyzer.ini to contain:Īs a rough guide, Memory Analyzer itself needs 32 to 64 bytes for each object in the analyzed heap, so -Xmx2g might allow a heap dump containing 30 to 60 million objects to be analyzed. Give it some more memory (possible by running on a 64-bit machine): Well, analyzing big heap dumps can also require more heap space. Out of Memory Error while Running the Memory Analyzer Version 1.4.2 of the JVM is not suitable for this product. Memory Analyzer version 1.1 will give a better error message pop-up. (This error happens because the MAT plug-in requires a JDK 1.8 via its manifest.mf file and the OSGi runtime dutifully does not activate the plug-in.) If in doubt, provide the runtime VM on the command line:Īlternatively, edit the MemoryAnalyzer.ini to contain (on two lines): The Memory Analyzer 1.8 to 1.11 needs a Java 1.8 VM or later VM to run (of course, heap dumps from JDK 1.4.2_12 on are supported). Memory Analyzer 1.12 and later needs a Java 11 VM or later VM to run. MemoryAnalyzer, Home Page, Forum Problems Starting the Memory Analyzer : No application id has been found.
