Cause 

the errors seen above are encountered because the NLS_LENGTH_SEMANTICS initialisation parameter has been set to CHAR. This is not a supported setting for this parameter in an Oracle Fusion Middle ware installation. This is documented in the Release Notes for each platform.

Solution 

To remove the ORA-01450 errors when creating the MDS and SOAINFRA components ensure that the requirement for NLS_LENGTH_SEMANTICS=BYTE is met.

To check the current setting of NLS_LENGTH_SEMANTICS, login to the target database as SYSDBA and issue the following command:

SQL> show parameter NLS_LENGTH_SEMANTICS

NAME                     TYPE        VALUE
———————— ———– ——-
nls_length_semantics     string      CHAR

SQL> alter system set nls_length_semantics=BYTE;

System altered.

SQL> show parameter NLS_LENGTH_SEMANTICS

NAME                     TYPE        VALUE
———————— ———– ——-
nls_length_semantics     string      BYTE

After resetting the parameter you should restart your database for the change to take effect.
