error when synchronizing CONTEXT index

Question

I have a full text database application with a simple procedure which inserts values into a table:

create or replace PROCEDURE put_file
 (
  p_file_name         IN my_doc.file_name%TYPE,
  p_upload_date       IN my_doc.upload_date%TYPE,
  p_filesize          IN my_doc.filesize%TYPE,
  p_filetype          IN my_doc.filetype%TYPE,
  p_creation_date     IN my_doc.creation_date%TYPE, 
  p_modification_date IN my_doc.modification_date%TYPE, 
  p_accessed_date     IN my_doc.accessed_date%TYPE
) AS
 dummy pls_integer;
 BEGIN

  select count(*) into dummy from my_doc where file_name = p_file_name;

  if dummy = 0
      then
         INSERT INTO my_doc (id, file_name, upload_date, filesize, filetype, content, creation_date, modification_date, accessed_date)
         VALUES (my_doc_seq.NEXTVAL, p_file_name, p_upload_date, p_filesize, p_filetype, BFILENAME('DOCUMENTS',p_file_name), p_creation_date, p_modification_date, p_accessed_date);

  end if; 
   ctx_ddl.sync_index;   -- the error occurs here
   COMMIT;

END;

In order to successfully execute this procedure, I provided all necessary rights to the current user:

grant resource, connect, ctxapp to my_user;
/
grant execute on ctxsys.ctx_adm to my_user;
grant execute on ctxsys.ctx_cls to my_user;
grant execute on ctxsys.ctx_ddl to my_user;
grant execute on ctxsys.ctx_doc to my_user;
grant execute on ctxsys.ctx_output to my_user;
grant execute on ctxsys.ctx_query to my_user;
grant execute on ctxsys.ctx_report to my_user;
grant execute on ctxsys.ctx_thes to my_user;
grant execute on ctxsys.ctx_ulexer to my_user;

... but, unfortunately, when I execute the procedure I receive the following error:

Error starting at line 1 in command:
EXECUTE put_file('text.txt', sysdate, 12, '.txt', sysdate, sysdate, sysdate);
Error report:

ORA-20000: Oracle Text error: DRG-10017: you must be CTXSYS to do this: SYNC

       *Cause: The stored procedure 'raise_application_error' was called which causes this error to be generated.
       *Action: Correct the problem as described in the error message or contact the application administrator or DBA for more information.

Can you tell me what am I doing wrong, please?

Thank you,

I think the problem I show you're calling ctx_ddl.sync_index. You're not passing any parameters. This is allowed but the documentation tells us:

"When idx_name is null, all CONTEXT, CTXRULE, and CTXXPATH indexes that have pending changes are synchronized. You must be connected as ctxsys to perform this operation. "

So the solution is you need to include the name of the index in your call.
