Data comparison


Data comparison is a new feature in Enterprise Manager Cloud Control 12c. You are now able to compare the data in different schemas or databases using this feature, which is primarily meant for smaller tables such as reference tables, configuration data, or seed data.

Note that the reference database must be of Version 11g or later; this is because it uses the DBMS_COMPARISON package, which is available from 11g onwards. The candidate database however can be of Version 10g or later.

The database character sets must be the same for both databases. Tables, single-table views, and materialized views can be used for data comparison.
