-- | designed to work with Oracle7 and Oracle8. This script can be |
-- | run against higher database versions (i.e. Oracle8i) but will |
-- | not return information about true TEMPORARY tablespaces. |
-- | (i.e. use of "tempfiles") |
-- | NOTE : As with any code, ensure to test this script in a development |
-- | environment before attempting to run it in production. |

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.
