ORA-23435: cannot create an updatable ROWID materialized view with LOB columns
Cause : The propagation of LOB data from materialized view sites to the master site requires a primary key on the replicated table. Thus updatable ROWID materialized views that contain LOB columns are not supported.
Action - How to fix it : DBA Scripts :: www.high-oracle.com/scripts
Create a primary key materialized view instead of a ROWID materialized view. If the materialized view already exists, it can be converted to a primary key materialized view using the ALTER MATERIALIZED VIEW DDL command.
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.
