Hi all,

I have a xml which is 3.08 MB in size. While I run the Transfer tool of
XML-DBMS, it gives me the following error. I read in previous posts that the DOM
parser builds the entire tree in the memory. Is there any option by which the
memory can be used more effectively? Can we perhaps replace the DOM parser with
SAX parser ?
