[升级] cpu used 100% when export AWR

1^#

发表于 2015-1-22 10:40:11 | 查看: 5915| 回复: 11

各位好：

昨天我在新环境上安装11.2.0.4，操作系统为LINUX ,在执行@?/RDBMS/ADMIN/AWRRPT时，持续时间将近10分钟，期间cpu使用率将近100% ，如下：
Cpu(s): 96.0%us,  3.3%sy,  0.0%ni,  0.0%id,  0.0%wa,  0.0%hi,  0.7%si,  0.0%st
Mem: 2075500k total,  1694588k used, 380912k free, 58424k buffers
Swap:  5116660k total,    92k used,  5116568k free,  1432396k cached

  PID USER    PR  NI  VIRT  RES  SHR S %CPU %MEM TIME+  COMMAND
9980 oracle 25 0  790m  94m  87m R 97.9  4.6  21:11.13 oracle
9902 oracle -2 0  783m  14m  12m S  2.0  0.7 0:23.01 oracle
alert日志未有明显信息
当时ASH 显示主要等待事件为CPU + Wait for CPU，
等待SQL语句为with sn as (select DBID, STAT_ID, STAT_NAME from DBA_HIST_STAT_NAME where STAT_NAME not in ('DB time', 'logons current', 'opened cursors current', 'workarea memory allocated', 'session cursor cache count', 'session uga memory', 'session uga memory max', 'session pga memory', 'session pga memory max') and STAT_NAME not like '%wait time' and dbid = 1397357371), s as (select distinct instance_number, stat_id from dba_hist_service_stat where dbid = 1397357371 and snap_id = 1) select b.stat_name st, e.value - b.value, round((e.value - b.value)/2, 2), round((e.value - b.value)/2, 2) from dba_hist_sysstat b, dba_hist_sysstat e where b.snap_id = 1 and e.snap_id = 1 and b.dbid = 1397357371 and e.dbid = 1397357371 and b.instance_number = 1 and e.instance_number = 1 and b.stat_id = e.stat_id and (e.stat_id, e.instance_number) not in (select stat_id, instance_number from s) and e.stat_id in (select stat_id from sn) and e.value >= b.value and e.value > 0 order by st，重新收集统计信息，手工跑这条语句，还是很慢，MOS上貌似找不到此问题解决办法，请大家给个解决思路，谢谢

FINDINGS SECTION (5 findings)
-------------------------------------------------------------------------------

1- Statistics Finding
---------------------
  Optimizer statistics for table "SYS"."WRH$_STAT_NAME" and its indices are
  stale.

  Recommendation
  --------------
  - Consider collecting optimizer statistics for this table.
execute dbms_stats.gather_table_stats(ownname => 'SYS', tabname =>
         'WRH$_STAT_NAME', estimate_percent =>
         DBMS_STATS.AUTO_SAMPLE_SIZE, method_opt => 'FOR ALL COLUMNS SIZE
         AUTO');

  Rationale
  ---------
The optimizer requires up-to-date statistics for the table in order to
select a good execution plan.

2- Statistics Finding
---------------------
  Optimizer statistics for table "SYS"."WRH$_SERVICE_NAME" and its indices are
  stale.

  Recommendation
  --------------
  - Consider collecting optimizer statistics for this table.
execute dbms_stats.gather_table_stats(ownname => 'SYS', tabname =>
         'WRH$_SERVICE_NAME', estimate_percent =>
         DBMS_STATS.AUTO_SAMPLE_SIZE, method_opt => 'FOR ALL COLUMNS SIZE
         AUTO');

  Rationale
  ---------
The optimizer requires up-to-date statistics for the table in order to
select a good execution plan.

3- Statistics Finding
---------------------
  Optimizer statistics for table "SYS"."WRH$_SERVICE_STAT" and its indices are
  stale.

  Recommendation
  --------------
  - Consider collecting optimizer statistics for this table.
execute dbms_stats.gather_table_stats(ownname => 'SYS', tabname =>
         'WRH$_SERVICE_STAT', estimate_percent =>
         DBMS_STATS.AUTO_SAMPLE_SIZE, method_opt => 'FOR ALL COLUMNS SIZE
         AUTO');

  Rationale
  ---------
The optimizer requires up-to-date statistics for the table in order to
select a good execution plan.

4- Statistics Finding
---------------------
  Optimizer statistics for table "SYS"."WRH$_SYSSTAT" and its indices are
  stale.

  Recommendation
  --------------
  - Consider collecting optimizer statistics for this table.
execute dbms_stats.gather_table_stats(ownname => 'SYS', tabname =>
         'WRH$_SYSSTAT', estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
         method_opt => 'FOR ALL COLUMNS SIZE AUTO');

  Rationale
  ---------
The optimizer requires up-to-date statistics for the table in order to
select a good execution plan.

5- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
  A potentially better execution plan was found for this statement.

  Recommendation (estimated benefit: 99.99%)
  ------------------------------------------
  - Consider accepting the recommended SQL profile.
execute dbms_sqltune.accept_sql_profile(task_name => 'TASK_15',
         task_owner => 'SYS', replace => TRUE);

Validation results
  ------------------
  The SQL profile was tested by executing both its plan and the original plan
  and measuring their respective execution statistics. A plan may have been
  only partially executed if the other could be run to completion in less time.
