Dear Colleagues,
I use NWDS 7.31 on Windows 7 64 Bit with SAP JVM 6 and get the following error while using the SAP memory analyzer tool
in NWDS to open a 3.7 GB heap dump:
I have 8GB RAM and it should be no problem to parse the heap dump. It seems I simply need to increase the heap space.
In the folder where the executable SapNetweaverDevloperStudio.exe resides, the SapNetweaverDeveloperSudio,.ni file is configured as
-vm
C:\Program Files (x86)\SAP\SAP JVM 6 (61_REL i486 opt)\bin
-startup
plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar
-nl
en
-vmargs
-Xmx512m
-Xms128m
-XX:PermSize=32m
-XX:MaxPermSize=384m
-Dfile.encoding=UTF-8
-Dosgi.requiredJavaVersion=1.6
-XX:+HeapDumpOnOutOfMemoryError
-Djavax.net.ssl.trustStoreProvider=SunMSCAPI
-Djavax.net.ssl.trustStoreType=Windows-ROOT
I increased -Xmx, but unfortunately, if -Xmx is set to 1024m or larger, NWDS does not start anymore.
What should I do? According to the error message I get, I should increase -Xmx to at least 1.7GB.
Ideally, I want to increase -Xmx as much possible in order to parse very large heap dumps.
Maybe I should first increase the allowed heap size on OS level and then edit again the *.ini file?
Thank you and kind Regards
Rainer
don't use nwds
download the memory analyzer(64bit) from http://www.eclipse.org/mat/downloads.php.
