Michael,
Thanks but I don't see this option on
http://www.saxonica.com/documentation/using-xquery/commandline.html nor
when I do "java -help".
Is it available for Saxon 8.9J (free version)?

How much heap space did you allocate?
My usual rule of thumb is 5x the raw document size, so this should run
if you allocate 1Gb (use the -Xmx option). That's an apporximation of
course, it's sometimes more, sometimes less.

Subject: [xquery-talk] Saxon: Java heap space problem
Hi,
When attempting to process a 200 MB file with Saxon 8.9J (Java
version 1.6.0_01), I run out of heap space.
Building tree for file:/D:/PFA/PFA_200509302000_F.xml using
class net.sf.sa
xon.tinytree.TinyBuilder
Exception in thread "main" java.lang.OutOfMemoryError: Java heap
space
at
net.sf.saxon.tinytree.TinyTree.ensureNodeCapacity(TinyTree.java:203)
at
net.sf.saxon.tinytree.TinyTree.addNode(TinyTree.java:292)
Since I'm already using the default "tiny tree" model, and
having closed down other applications, short of adding more physical
memory, is there anything else I can do? If it matters, this large file
is only 2 "lines": the XML declaration and the rest of the file.
Is there anyway of getting a ballpark handle on the max size of
file I can process with Saxon (and Java) if my physical memory is say
"N" MB?
Total Physical Mem = 2.048 GB
Available Physical Mem = 1.22 GB
Total Virtual Mem = 2.00 GB
Available Virtual Mem = 1.96 MB
Page File Space = 3.85 GB
Thanks!
