How do I make "one transaction" become "many transactions"? The file is uploaded when creating a new "File" object. -Chris Eric Balasbas wrote:
Sounds like the problem is with inserting many rows into the database in one transaction. Breaking up the inserts into many transactions should help. How exactly do you put the csv file into Zope?

For a project we are working on we have export of an MS Access database as csv (comma seperated) files. The csv file is about 37MB with rows of 18 numbers sepearted by commas. The file has been uploaded into Zope and then we are trying to insert each row into a PostgreSQL database using either the PoPy or PsycoPG database adapter. Basically Zope never comes back from trying to do this. We have also tested against Oracle with the same results. It's been run on an Athlon 600 and a Sun E450. Zope just starts to take up more and more memory eventually filling up swap and never completing the transaction. If we split the 37MB file up into small 3-4MB chunks, everything works fine. But it just can't handle the larger file. To me, 37MB doesn't seem like much. If it were .5GB, I could understand Zope having problems. How can I get this to work?
I am not on the zope list (though I'll probably subscribe here in a moment) so please CC me on a reply.
Thanks, -Chris
