Getting DRG-50858: OCI error: OCI_NO_DATA with user_datastore on 9iR2

Question

Hi there,
Created a procedure and mapped it to a user_datastore... getting the following error in the ctx error table:
DRG-12604: execution of user datastore procedure has failed
DRG-50857: oracle error in drsinopen
DRG-50858: OCI error: OCI_NO_DATA
Created the following preferences:
begin
-- set the user datastore procedure
ctx_ddl.create_preference('ccnews_ud', 'user_datastore');
ctx_ddl.set_attribute('ccnews_ud', 'procedure', 'ctxsys_ccnews_ustore_idx_prc');
ctx_ddl.set_attribute('ccnews_ud', 'output_type', 'CLOB');
ctx_ddl.create_preference('english_lexer','basic_lexer');
ctx_ddl.create_preference('french_lexer','basic_lexer');
ctx_ddl.create_preference('global_lexer', 'multi_lexer');
ctx_ddl.add_sub_lexer('global_lexer','default','english_lexer');
ctx_ddl.add_sub_lexer('global_lexer','ENGLISH','english_lexer','1');
ctx_ddl.add_sub_lexer('global_lexer','FRENCH','french_lexer','2');
end;
Is it possible that the procedure returns an empty clob for a row which causes this problem?
The index is running on a table with 28,000 rows, I have to admint that the data integrity is not up to par (ie could be existence of orphaned records) Could this cause the problem?

Answer 1

An empty clob or even an orphaned record should not cause the problem. It is usually due to a bug in the procedure. Data corruption could be a cause. Please post a copy and paste of a run of create or replace for your procedure, followed by show errors and a copy and paste of a run of a query that produces the error stack.
