-- | DATABASE : Oracle |
-- | FILE : dba_compare_schemas.sql |
-- | CLASS : Database Administration |
-- | PURPOSE : This script can be used by developers and DBAs to compare two |
-- | Oracle schemas. This script will generate a report of all |
-- | object discrepancies between two Oracle database schemas. |
-- | |
-- | This script has been tested on the following Oracle database |
-- | versions: 7.3, 8, 8i, 9i, 10g, 11g. |
-- | |
-- | At this time, the following schema object types (and |
-- | attributes) are not compared and reported on within the |
-- | detailed discrepancy sections. Most of them, however, will |
-- | appear in the "Summary" section of the report. |
-- | |
-- | - Comments (On either tables nor columns.) |
-- | - Partitions (Introduced in Oracle8) |
-- | - Object types (Introduced in Oracle8) |
-- | - Nested tables (Introduced in Oracle8) |
-- | - Dimensions (Introduced in Oracle8i) |
-- | - Cluster definitions |
-- | - Auditing metadata |
-- | - Index organized tables (Introduced in Oracle8i) |
-- | - Temporary tables (Introduced in Oracle8i) |
-- | - Snapshots (Also known as materialized views |
-- | in Oracle8 and higher. Also no |
-- | details on snapshot logs and |
-- | refresh groups will be |
-- | generated.) |
-- | - New schema attributes (Introduced in Oracle 9i) |
-- | |
-- | NOTE : As with any code, ensure to test this script in a development |
-- | environment before attempting to run it in production. |

PROMPT | COMPARE SCHEMA SCRIPT |
PROMPT |------------------------------------------------------------------------|
PROMPT | |
PROMPT | USAGE |
PROMPT | -----------------------------------------------------------------------|
PROMPT | This SQL script should be run while connected to the Oracle database |
PROMPT | as one of the schemas you would like to compare. You will be prompted |
PROMPT | to enter the Oracle username, password, and Oracle Net Service Name of |
PROMPT | the second (remote) schema you would like to compare against. Lastly, |
PROMPT | you will be asked for the filename of the report you would like this |
PROMPT | script to create for all generated discrepancies. (You can hit [ENTER] |
PROMPT | to accept the default file name.) |
PROMPT | |
PROMPT | NOTE |
PROMPT | -----------------------------------------------------------------------|
PROMPT | The following database objects will be created for use by this script. |
PROMPT | |
PROMPT | [*] Database Link (remote_schema_link) |
PROMPT | [*] Table (schema_compare_temp) |
PROMPT | [*] PL/SQL Procedure (getLongText) |
PROMPT | [*] PL/SQL Procedure (getLongText2) |
PROMPT | |
PROMPT | These objects will be dropped at the end of this script. |
