通過存儲過程自動生成AWR報告

以下是存儲過程內容(需要預先在/opt/awrreport創建目錄名dir_awrreport)：

CREATE OR REPLACE PROCEDURE sp_auto_awrreport(reporttime varchar2 default null,
                                              rpt_interval number default 2) 
AS
----用途：自動生成AWR報告
----創建人：cavlin
----創建日期：20130210
----reporttime 報告結束時間
----rpt_interval 報告間隔 1:30分鐘,2:60分鐘
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
    ---查詢最大的快照id
    select max(snap_id) into end_snap from dba_hist_snapshot;
    start_snap:=end_snap-rpt_interval;
  else
    ---取輸入時間對應的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;

---格式化快照時間
  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;

---實例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);

---實例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;

可以直接在數據庫中調用，也可以通過shell調用：

#!/bin/bash

export ORACLE_HOME=/opt/oracle/product/10.2.0/db_1
export ORACLE_SID=STATRAC1
export PATH=$ORACLE_HOME/bin:/usr/sbin:/home/oracle/bin:$PATH

echo "awrruning date: `date +"%F.%T"`">/opt/awrreport/awrrun.log

sqlplus -s / as sysdba << EOF
exec sp_auto_awrreport;
exit
EOF

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

 

通過crontab調用：

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

 

這樣每天22點05分就會在/opt/awrreport目錄自動生成21：00--22：00的awr報告了。
