Re: [basex-talk] basexhttp out of memory where basexgui suceeds
Hi Jack,
If you run the query via basexhttp, how do you retrieve the results, i.e.,
which client do you use?
Can you possibly provide us with a self-contained example, something like…
for $i in 1 to 50
return update {
insert node into .
}
…and some steps to reproduce the behavior?
Thanks in advance,
Christian

Re: [basex-talk] basexhttp out of memory where basexgui suceeds
Sorry, the first line of the script should end with
/*/*
Could the problem be related to UPDINDEX, AUTOOPTIMIZE and/or FTINDEX all
being set to true on basexhttp but false on basexgui? I thought it wouldn't
make a difference because the updates occur in main memory, but perhaps it
does.
Best,
Jack

[basex-talk] basexhttp out of memory where basexgui suceeds
Hi,
I have a database about 200 MB in size made up of approximately 150 000
documents of similar size and structure as children of the root node.
When I run the following script in basexgui a significant amount of memory
is consumed (over 1 GB if I'm reading the display correctly), but I do get
a result:
for $doc in db:get('docs')
return $doc update {
delete node .//*[local-name() = ('A', 'B', 'C', 'D')]
}
When I run it over basexhttp I get a java.lang.OutOfMemoryError: Java heap
space. I have increased the memory available to the JVM to 4 GB but this
has not affected the failure of the script.
How can I resolve this? Is there some rewriting of the script that would
help, or is it more specific to basexhttp?
Many thanks,
Jack
