I was wondering if anyone new of a software package we could buy that would help with releasing database changes from development to production. For example, if I had to make a release of some changes to packages, new tables,table changes and a new sequence number. Is there a software package anyone out there knows of that would back up these areas in the target database, implement the changes and then give me the option of restoring what was in the database before I made the changes if there is a problem? Right now I write unix script to do this for each release and I was wondering if there is any easier way.
