ORA-16709: standby archived log location settings conflict with flash recovery area
Cause : The flash recovery area was already set up on the standby database for storing incoming archived logs from the primary database. In this case, the StandbyArchiveLocation and AlternateLocation properties should not be used for setting up a standby archived log location. The Data Guard broker raised this error because it detected one of the following: (1) the user attempted to use the StandbyArchiveLocation or AlternateLocation properties to set up a standby archived log location; (2) On the standby database, a local destination corresponding to the StandbyArchiveLocation or AlternateLocation property was still set up to store archived logs from the primary database.

If you get this error when trying to set property StandbyArchiveLocation or AlternateLocation (case (1) above), avoid setting these properties. If you get this error after a broker health check (case (2) above), reenable the standby database to clear the error.
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.
