sql tunning advisor 使用的主要步驟:
1 建立tunning task
2 執(zhí)行task
3 顯示tunning 結(jié)果
4 根據(jù)建議來(lái)運(yùn)行相應(yīng)的調(diào)優(yōu)方法 ----ADVISOR授權(quán)

在紅崗等地區(qū)，都構(gòu)建了全面的區(qū)域性戰(zhàn)略布局，加強(qiáng)發(fā)展的系統(tǒng)性、市場(chǎng)前瞻性、產(chǎn)品創(chuàng)新能力，以專注、極致的服務(wù)理念，為客戶提供成都做網(wǎng)站、網(wǎng)站建設(shè) 網(wǎng)站設(shè)計(jì)制作按需開(kāi)發(fā)網(wǎng)站,公司網(wǎng)站建設(shè),企業(yè)網(wǎng)站建設(shè),成都品牌網(wǎng)站建設(shè),網(wǎng)絡(luò)營(yíng)銷推廣,外貿(mào)網(wǎng)站制作,紅崗網(wǎng)站建設(shè)費(fèi)用合理。

1 基于SQL文本建立任務(wù)

FUNCTION create_tuning_task(
sql_text IN CLOB,
bind_list IN sql_binds := NULL,
user_name IN VARCHAR2 := NULL,
scope IN VARCHAR2 := SCOPE_COMPREHENSIVE,
time_limit IN NUMBER := TIME_LIMIT_DEFAULT,
task_name IN VARCHAR2 := NULL,
description IN VARCHAR2 := NULL)
RETURN VARCHAR2;

2 基于sql_id建立任務(wù)
FUNCTION create_tuning_task(
sql_id IN VARCHAR2,
plan_hash_value IN NUMBER := NULL,
scope IN VARCHAR2 := SCOPE_COMPREHENSIVE,
time_limit IN NUMBER := TIME_LIMIT_DEFAULT,
task_name IN VARCHAR2 := NULL,
description IN VARCHAR2 := NULL)
RETURN VARCHAR2;

3 基于AWR快照間隔以及相應(yīng)SQL_ID建立任務(wù)
FUNCTION create_tuning_task(
begin_snap IN NUMBER,
end_snap IN NUMBER,
sql_id IN VARCHAR2,
plan_hash_value IN NUMBER := NULL,
scope IN VARCHAR2 := SCOPE_COMPREHENSIVE,
time_limit IN NUMBER := TIME_LIMIT_DEFAULT,
ask_name IN VARCHAR2 := NULL,
description IN VARCHAR2 := NULL)
RETURN VARCHAR2;

案例：
DECLARE
MY_TASK_NAME VARCHAR2(30);
MY_SQLTEXT CLOB;
BEGIN
MY_SQLTEXT :='SELECT 1 from dual';
MY_TASK_NAME := DBMS_SQLTUNE.CREATE_TUNING_TASK(SQL_TEXT => MY_SQLTEXT,
BIND_LIST=>SQL_BINDS(ANYDATA.CONVERTNUMBER(9)),
USER_NAME => 'NOAP',
SCOPE=>'COMPREHENSIVE',
TIME_LIMIT => 600,
TASK_NAME => 'SQL_TUNING_TEST',
DESCRIPTION=>'TUNING TASK'
);
END;

BEGIN DBMS_SQLTUNE.EXECUTE_TUNING_TASK('SQL_TUNING_TEST'); END;
SELECT status FROM USER_ADVISOR_TASKS WHERE task_name ='SQL_TUNING_TEST';
SELECT DBMS_SQLTUNE.REPORT_TUNING_TASK('SQL_TUNING_TEST') FROM DUAL;
BEGIN dbms_sqltune.drop_tuning_task('SQL_TUNING_TEST'); END;
