1.使用 CREATE_BASELINE_TEMPLATE 存储过程创建 single baseline template： col BASELINE_NAME for a30 TEMPLATE_NAME for a30 select DBID,BASELINE_ID,BASELINE_NAME,BASELINE_TYPE,EXPIRATION,TEMPLATE_NAME from dba_hist_baseline; DBID BASELINE_ID BA
1.使用 CREATE_BASELINE_TEMPLATE 存储过程创建 single baseline template：
col BASELINE_NAME for a30
TEMPLATE_NAME for a30
select DBID,BASELINE_ID,BASELINE_NAME,BASELINE_TYPE,EXPIRATION,TEMPLATE_NAME from dba_hist_baseline;
DBID BASELINE_ID BASELINE_NAME BASELINE_TYPE EXPIRATION TEMPLATE_NAME

2.使用 CREATE_BASELINE_TEMPLATE 存储过程创建 repeating baseline template：
--创建一个 repeating baseline template，在 2013 年每周星期一下午5点到晚上8点之间生成一个 baseline：
BEGIN
DBMS_WORKLOAD_REPOSITORY.CREATE_BASELINE_TEMPLATE (
day_of_week => 'monday', hour_in_day => 17,
duration => 3, expiration => 30,
start_time => '2013-03-10 17:00:00',
end_time => '2013-12-31 20:00:00',
baseline_name_prefix => 'baseline_2013_mondays_',
template_name => 'template_2013_mondays',
dbid => 220853307);
END;
/
-- 对比 single baseline template 和 repeating baseline template
select * from dba_hist_baseline_template;
DBID TEMPLATE_ID TEMPLATE_NAME TEMPLATE_TYPE BASELINE_NAME_PREFIX START_TIME END_TIME DAY_OF_WEEK HOUR_IN_DAY DURATION EXPIRATION REPEAT_INTERVAL LAST_GENERATED
---------- ----------- ------------------------------ ------------- ------------------------------ ----------- ----------- ----------- ----------- ---------- ---------- -------------------------------------------------------------------------------- --------------

3.删除 baseline template
BEGIN
DBMS_WORKLOAD_REPOSITORY.DROP_BASELINE_TEMPLATE (
template_name => 'template_2013_mondays',
dbid => 220853307);
END;
/
select * from dba_hist_baseline_template;

---------- ----------- ------------------------------ ------------- ------------------------------ ----------- ----------- ----------- ----------- ---------- ---------- -------------------------------------------------------------------------------- --------------
