Hello, So I've run into a problem. I had the need to migrate our a database of people from an old storage format to a new one. The old format uses Folders and Properties to store information about a person. Name, phone, email, address, etc. The new format uses a Product that I wrote which stores said data in a ParsedXML document. I have roughly 1,500 people in the database. I wrote a script to migrate the people. Basically it does getProperty for each property on each person folder, then creates the new person object which uses XML. Zope apparently cannot handle this number of operations in one transaction. Zope gets slower and slower and eventually becomes on responsive. It looks like the script has completed, but nothing is ever committed to the ZODB, and since Zope is unresponsive it must be restarted. This, as expected, kills that entire transaction which was never committed. Is it known that large numbers of operations, such as above, in a single transaction can cause problems? A transaction, of course, being a request, and an operation being something like manage_addProduct. I've solved the "problem" by using xmlrpc and for person in people calling my migrate_person script for only one person at a time. This is SO MUCH FASTER. I previously ran the script that migrates all of the people, and after 8 hours it still had not completed. Thoughts? -Chris
