Compare Oracle Databases Tips

Oracle Database Tips by Donald BurlesonMay 20, 2015

Question:  I need to find a method to compare two databases in Oracle.  I need the comparison of the databases to show differences in tables columns and indexes.  What are the tools to compare Oracle databases?

Answer:  There are many third-party tools to compare databases, but I would start with the Oracle Corporation database compare utilities, found in OEM and Oracle SQL Developer.

There are Several Tools Used for Comparing databases.  Here are some common third-party vendor Oracle database comparison tools:

1 - Starting in 11g, you can also use the dbms_comparison utility to see the differences between two databases.  The book Advanced Oracle DBMS Packages has complete details on using the package.

2-Jeff Hunter - compare_schemas.sql


4-Oracle Enterprise Manager (OEM).

5- DBSOLO - Compare any Two Database .

6-RedGate to Compare Data, schema , Database .

Also, be sure to check-out all freeware tools for Oracle, some of which compares tables and indexes.
