I'm looking for a database schema comparison tool that runs on Linux, handles Oracle databases, and can generate a synchronization script to migrate one schema to another. TOAD does this very well on Windows, but doesn't run on Linux. Free and open source is preferred, but not required. It would also be nice if it is scriptable, enabling it to be run as a cron job, for example. Anything like that out there?
BTW- I have looked at Oracle's own SQL Developer tool, and although it supports comparisons, there were a lot of false positives in my tests. For example, it flagged foreign keys that were identical as being different.
