ORA-29880: such column list already indexed using another domain index and indextype
Cause : An attempt was made to create multiple domain indexes on a column list using indextypes which do not have disjoint operators.
Action - How to fix it : DBA Scripts :: www.high-oracle.com/scripts
Check to see if the operator sets for the indextypes can be made disjoint.
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.
