Hi Andreas and thanks for your answer,

unfortunely that didn’t work (java.exe consumed 1.2 GB, then stopped). The expected result should not be longer then about 10 element names or so...

Maybe this could be a bug in basex itself…?

Hi,

as first hint you could start BaseX with the Xmx flag of Java:

java -cp BaseX.jar -Xmx1G org.basex.BaseXGUI

Probably that will solve this issue.

Kind regards,

Andreas

Hi there,

I’m currently doing some tests with BaseX and a mid-sized database (around 2 GB).

I wonder myself why I’m not able to process this xquery-statement:

dinstinct-values(//*[randnr]/name())

(„Give me a list of all elements which have a child-element <randnr> and remove all double entries“)

After about 10 seconds a got a „out of main memory“ error. What’s really strange about this: Processing the nodes itself with //*[randnr]/

works like a charm (but gives me a HUGE amount of text and is not really useful for me at all).

My system: win7-x64, 4 GB RAM, Java 1.6.0_21

Thank you in advance,

Rupert Jung
