Could you please provide some additional information:
1. make the following settings
set linesize 1000
set pagesize 1000
2. then run
alter session set statistics_level=all;
3. then run your sql,
4. after that run the following select:
select plan_table_output from table ( sys.dbms_xplan.display_cursor( '','','ADVANCED ALLSTATS LAST'));
5. upload the last formatted output.
