Error during upgrade from 12.1.0.2 to 18.4: ORA-01422: ORA-06512: at "SYS.CDBVIEW_INTERNAL"

Hi,

During an upgrade from 12.1.0.2 to 18.4 I received the following 2 errors:

1)

create index i_radm_pe2 on sys.radm_pe$(pe_obj#, pe_name)

                               *

ERROR at line 1:

ORA-01450: maximum key length (3118) exceeded

2)

   ORA-01422: exact fetch returns more than requested number of rows

   ORA-06512: at "SYS.CDBVIEW_INTERNAL", line 199

   ORA-06512: at "SYS.CDBVIEW_INTERNAL", line 6

The database being upgraded is a 4K database.  I have seen some bugs related to 2 and 4K databases, but not a direct match.  I should also note this is on an AIX Power-64 platform.

The result is that it leaves the "oracle_server" component in an "invalid" state.
