以下是存储过程内容: CREATE OR REPLACE PROCEDURE sp_auto_awrreport(reporttime varchar2 default null,

以下是存储过程内容:

CREATE OR REPLACE PROCEDURE sp_auto_awrreport(reporttime varchar2 default null,
rpt_interval number default 2)
AS
----用途:自动生成AWR报告
----创建人:cavlin
----创建日期:20130210
----reporttime 报告结束时间
----rpt_interval 报告间隔 1:30分钟,2:60分钟
start_snap number;
end_snap number;
start_time varchar2(14);
end_time varchar2(14);
awr_file utl_file.file_type;
n_dbid number;

BEGIN

if reporttime is null then
---查询最大的快照id
select max(snap_id) into end_snap from dba_hist_snapshot;
start_snap:=end_snap-rpt_interval;
else
---取输入时间对应的snap_id
select snap_id
into end_snap
from dba_hist_snapshot
where to_char(end_interval_time, 'yyyymmddhh24mi') = reporttime
and instance_number = 1;
start_snap:=end_snap-rpt_interval;
end if;

---格式化快照时间
select dbid,to_char(end_interval_time-rpt_interval/48, 'yyyymmddhh24mi'),to_char(end_interval_time, 'yyyymmddhh24mi')
into n_dbid,start_time,end_time
from dba_hist_snapshot
where snap_id = end_snap and instance_number=1;

---实例1
awr_file:=utl_file.fopen('DIR_AWRREPORT','AWR_NODE1_'||start_time||'_'||end_time||'.html', 'a',32767);
for awr_info in (select output from table(dbms_workload_repository.awr_report_html(n_dbid,1,start_snap,end_snap,0))) loop
UTL_FILE.put_line(awr_file,awr_info.output);
end loop;
utl_file.fclose(awr_file);

---实例2
awr_file:=utl_file.fopen('DIR_AWRREPORT','AWR_NODE2_'||start_time||'_'||end_time||'.html', 'a',32767);
for awr_info in (select output from table(dbms_workload_repository.awr_report_html(n_dbid,2,start_snap,end_snap,0))) loop
UTL_FILE.put_line(awr_file,awr_info.output);
end loop;
utl_file.fclose(awr_file);

END sp_auto_awrreport;

可以直接在数据库中调用,,也可以通过shell调用:

cat /opt/cron/autoawr.sh
#!/bin/bash

sqlplus -s / as sysdba exec sp_auto_awrreport;
exit
EOF

find /opt/awrreport/ -mtime +7 -name "*.html" -exec rm -f {} \;

通过crontab调用:

$ crontab -l
5 22 * * * sh /opt/cron/autoawr.sh

这样每天22点05分就会在/opt/awrreport目录自动生成21:00--22:00的awr报告了。
