    It would be great if we can have this tool for  Netweaver 2004 (640) and also Netweaver 2004s (700).

    Please let me know if there are any such kind of tools for the same.

  3. Thanks for your comments. The network connection problems are most probably related to the fact, that you are accessing the Internet through a proxy. Please see my brief explanation how to download through a proxy.

    I am unfortunately not aware of similar tools like the SAP JVM Profiler for use with NW 2004(s).

    Try without the "http://" part of the proxy name. Or try using just the proxy's IP address.

    First, I'm new to all this SCN-Stuff, so I moved my question here:

      Hi Thomas,

      you don't need to update the SAP JVM or install the microsoft redistribution packet (in fact the profiler also runs on other Java runtimes). There seems to be a problem with the installed eclipse plugins. There should be a folder named "com.sap.jvm.profiling.ui.widgets_2.0.17" located in the plugins folder of your eclipse installation. Within this folder there should be "profiling_2.0_ui_widgets.jar" containing the missed class.

      Btw. have you set -XX:+HeapDumpOnOutOfMemoryError ? If yes, the JVM creates a heap dump when such an error occurs which you can analyze with the Memory Analyzer and inspect potential memory leaks. Alternatively you can trigger a heap dump whenever you want to with the command-line tool jvmmon (command 'dump heap').

      The poor performance after some months could to be related the heavy GC activity (probably due to the memory leak or shortage). If your JVM was started with -XX:+GCHistory you also get a log of all GCs that happend (use command 'retrieve complete gc history' in a jvmmon session to get the file). This file can be imported into Profiler 2.0 for graphical GC analysis.
