使用模板来创建工作量
1.创建变量

SQL> variable template_id number;
SQL> variable template_name varchar2(255);

2.创建名叫my_wk_template的模板

SQL> execute :template_name := 'my_wk_template';

PL/SQL procedure successfully completed
template_name
---------
my_wk_template
SQL> execute dbms_advisor.create_sqlwkld(:template_name, is_template=>'true');

PL/SQL procedure successfully completed
template_name
---------
my_wk_template

3.设置模板参数。下面设置过滤只有insur_changde方案中的表被优化:

SQL> -- set USERNAME_LIST filter to insur_changde
SQL> execute dbms_advisor.set_sqlwkld_parameter(:template_name, 'USERNAME_LIST',  'insur_changde');

PL/SQL procedure successfully completed
template_name
---------
my_wk_template

4.使用模板来创建工作量

SQL> variable workload_name varchar2(255);
SQL> execute :workload_name := 'myworkload';

PL/SQL procedure successfully completed
workload_name
---------
myworkload
SQL> execute dbms_advisor.create_sqlwkld (:workload_name, 'this is my first workload',  'my_wk_template');

PL/SQL procedure successfully completed
workload_name
---------
myworkload
