Carlton and Mike, Attached are two different sets of files (one zip, one tar) I got for manipulating the ONPLOAD database outside of the GUI. These came from field engineers. I have not tested them, nor am I sure how well they work or are documented. However, because this was such a hot issue at the Large Scale Data Warehouse User Group meeting, I did want to get them out there for our users. Let me know if you have any questions about them or any feedback on their use. Please note that they are unsupported by Informix itself. Thanks for your assistance. Regards, Jim McCann Technology Manager Advanced Technology Group Informix Software
