DBDiff for Oracle is an ODBC tool that allows you to compare two Oracle databases. The comparison is fully customizable and creates a user friendly report stating all differences found in the privileges, sequences, tables, indexes, constraints, data, triggers, views, functions, procedures, and/or packages in the databases. This is a trial, and only the first five objects of each type per database are compared.
Ver. 2.0 includes an upgrading feature that automatically generates upgrade statements from source to target database. New free sql compare allows you to compare the results of any sql query between both databases. Command line support now allows you to execute pre-saved configuration completely unattended. Native connectivity to Oracle has been added. And many more features and bug fixes.
