ORA-01403: no data found on ctxposup.sql while upgrading from 11g to 12.2

From: Oracle Database - Enterprise Edition - Version 11.2.0.3 + PSU 11.2.0.3.5 (14727310)
To:   Oracle Database - Enterprise Edition - Version 12.2.0.1.0
Operation System -  Solaris 10 1/13 s10s_u11wos_24a SPARC


It failed to upgrade database from 11.2.3 to 12.2 with error 'ORA-01403: no data found', and following message is found from log file 'Oracle_Server.log',

Script ctxposup.sql (STATEMENT 1) which upgrades Oracle Text raised ORA-01403 while running PL/SQL block listed in the above. Testing individual statements in the block as following:

sys@DB01> select user#  from sys."_BASE_USER" where name='CTXSYS';

     USER#
----------
       100

sys@DB01> ALTER SESSION SET CURRENT_SCHEMA = CTXSYS;

Session altered.

sys@DB01> select idx_id from dr$index where
  2    idx_name = 'ENT_EXT_DICT_OBJ' and
  3    idx_owner# = 100;

no rows selected

The object CTXSYS.ENT_EXT_DICT_OBJ (a policy of Oracle Text) does not exist in the database. Therefore, STATEMENT 2 (select ... into ... from) returned ORA-01403. Apparently, The purpose of STATEMENT 2 is to test whether CTXSYS.ENT_EXT_DICT_OBJ exists, but listing records is not a better choice for exist-testing than counting the number of records. Let's try to replace STATEMENT 2 in script filectxposup.sql with following code

 select count(idx_id) into l_count from dr$index where

Start the upgrade again, it succeeded!
