Hello Christian, to check that your memory tweaks are effective, in QizxStudio you can look either on the bottom left of the main window, or use Help|About there is a section about the JVM at the bottom.
A 600 Mb document can use from 1000 Mb to 1800 Mb of main memory depending on the number of nodes, attributes etc. Now it also depends on your queries: for example if you do a large join, that can use additional memory. So perhaps try to increase even beyond 2 Gb. best regards -- Xavier Franc Qizx design and development On Tue, 10 Apr 2012 11:50:38 +0200, Dr. Christian Dugast <dug...@tech2biz.eu> wrote: > Hello, > > > I have just downloaded your xquery studio to try it on large amount of > data. > > > I have html (xml compatible) files from 100 MB up to 600MB on which I > want > to run a Xquery. > > > My Xquery runs well on a portion of my data (let’s say with 50 MB). > > When I want to run it on the whole data I get the error: error > OutOfMemoryError: Java heap space > > > I have set VMOPTS="-Xmx1024m $VMOPTS" even to 2048 (see attached file). > > I rerun the query and still have the same error message from the query. > > > I have also set the JVM parameters to the same values (I am not sure if > it > is not the same as setting VMopts in your environment).
