ORA-14134: indexes cannot use both DESC and REVERSE
Cause : An attempt was made to make a reverse index with some index columns marked DESC.
Action - How to fix it : DBA Scripts :: www.high-oracle.com/scripts
Do not use DESC in reverse indexes. The rule-based optimizer can scan indexes backwards, which allows a normal reverse index to simulate a reverse index with columns marked DESC.
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.
