I am working as a junior DBA. I tried to tune a query using SQL Tuning Advisor that is with DBMS_SQLTUNE.I have created the tuning task successfully with DBMS_SQLTUNE.create_tuning_task.But when i execute the tuning task with EXEC DBMS_SQLTUNE.execute_tuning_task() i got an error like

SQL> EXEC DBMS_SQLTUNE.execute_tuning_task(task_name => 'rep_three');

BEGIN DBMS_SQLTUNE.execute_tuning_task(task_name => 'rep_three'); END;

ERROR at line 1:

ORA-06512: at line 1

The oracle version is Oracle Database 10g Enterprise Edition Release 10.2.0.2.0 - 64bi. The OS is HP-UX. The version is HP-UX B.11.23 U ia64.

I tried to execute DBMS_SQLTUNE as DWH user.I have granted the advisor,DROP ANY SQL PROFILE,ALTER ANY SQL PROFILE,CREATE ANY SQL PROFILE privileges and DBA roles to the DWH user. The way i ran DBMS_SQLTUNE is, first i logged in as DWH user and i tried to execute the query for getting the SQL_ID for the query. For getting the SQL_ID i selected the SQL_ID column value for the DWH user session from v$session.I kept that query executing and meanwhile i opened another session as DWH user and created the tuning task as follows

DECLARE
l_sql_tune_task_id VARCHAR2(100);
BEGIN
l_sql_tune_task_id := DBMS_SQLTUNE.create_tuning_task (
sql_id => 'b65fj39dkkb9v',
scope => DBMS_SQLTUNE.scope_limited,
time_limit => 3600,
task_name => 'rep_three',
description => 'Report Tuning');
DBMS_OUTPUT.put_line('l_sql_tune_task_id: ' || l_sql_tune_task_id);
END;
/

The creation of tuning task was successful.And i executed the tuning task as follows

EXEC DBMS_SQLTUNE.execute_tuning_task(task_name => 'rep_three');

The above mentioned errors came when i executed the tuning task.

I am also adding the query which i have tried to tune

The above query also tries to access some tables from another user DISADMIN. Could you please help me in solving this problem ? I am the only DBA here.
