-- | 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 | |
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. |

Oracle Database Error Messages



Oracle Database High Availability Any organization evaluating a database solution for enterprise data must also evaluate the High Availability (HA) capabilities of the database. Data is one of the most critical business assets of an organization. If this data is not available and/or not protected, companies may stand to lose millions of dollars in business downtime as well as negative publicity. Building a highly available data infrastructure is critical to the success of all organizations in today's fast moving economy.

Well, the reason for above error is that i have taken the above script from a 11g database and running it on 10g database. 11g has bring some changes in password management. Below code is executed on 11g and user created successfully, which is expected result.
