Cause of the Problem
The quick_tune procedure performs an analysis and generates recommendations for a single SQL statement.
SQL Access Advisor maintains an internal list of non-tunable tables regardless of the contents of the INVALID_TABLE_LIST parameter.
The table owned by SYS, SYSTEM or any other pre-defined Oracle schema can be tuned and hence will return error.
Solution of The problem
Create the table in other schama rather than SYS, SYSTEM or any other pre-defined Oracle schema and run quick_tune procedure.
SQL> create table arju.emp(empno number);
Table created.
SQL> BEGIN
DBMS_ADVISOR.quick_tune(
advisor_name => DBMS_ADVISOR.SQLACCESS_ADVISOR,
task_name => 'emp_quick_tune',
attr1 => 'SELECT * FROM arju.emp WHERE EMPNO = 7788');
END;
