Oracle Text Index Error - DRG-10700: preference does not exist: CTXSYS.DEFA

Question

Hi we are having a Oracle 11g db.And we have installed CTX SYS package and provided the grants to the required schema.
But while creating the oracle text index, following error is thrown:
ORA-29855: error occurred in the execution of ODCIINDEXCREATE routine
ORA-20000: Oracle Text error:
DRG-10700: preference does not exist: CTXSYS.DEFAULT_LEXER
ORA-06512: at "CTXSYS.DRUE", line 160
ORA-06512: at "CTXSYS.TEXTINDEXMETHODS", line 365
Following grnats are given :
GRANT EXECUTE ON CTXSYS.CTX_DDL TO <schema_name>;
GRANT APPOWN TO <schema_name>;
GRANT CTXAPP TO <schema_name>;
I have verifyed the ctxsys.CTX_PREFERENCES view which is having an entry as :
SELECT PRE_OWNER, PRE_NAME
FROM CTXSYS.CTX_PREFERENCES
WHERE PRE_NAME = 'DEFAULT_LEXER';
The Result is :
PRE_OWNER     PRE_NAME
SYS     DEFAULT_LEXER
Can you please assist if there is a way to update the permission on this DEFAULT_LEXER preference to set the PRE_OWNER as CTXSYS ?
Thanks

Answer 1

That's odd. If I run the same query I see:
SQL> SELECT PRE_OWNER, PRE_NAME
  2  FROM CTXSYS.CTX_PREFERENCES
  3  WHERE PRE_NAME = 'DEFAULT_LEXER';
PRE_OWNER                      PRE_NAME
CTXSYS                         DEFAULT_LEXERAre all your defaults like thsi? What do you see if you run
select pre_owner, pre_name from ctxsys.ctx_preferences where pre_name like 'DEFAULT%';
It would be easy enough to update the underlying table DR$PREFERENCES to fix the owner, but who knows what else might be wrong.
Has this database been updated from a 9i installation by any chance?
