Re: Very URGENT! Tablespace Extent Problem w/ Import

Hi Howard.

I have edited MANY dump files with text editors (both Unix & NT) and have never had a problem. Granted the 'create table first' solution was probably better, but for small changes it sometimes seems easier to just edit the dump file.

I was also trying to explain the problem a little bit :)

Regards,

Dave Haas
