Statspack安装配置使用说明

Statspack安装配置使用说明
eygle ([email protected])

在数据库管理中,Oracle提供的statspack是一个很强大的工具,通过Statspack,可以收集系统信息,诊断数据库故障,也方便第三方技术支持进行远程阅读和建议。

看到很多人还不太了解这个工具的使用,论坛上同样的问题很多,所以写了一下一个说明文档,主要涉及安装配置和数据收集。

希望通过这些文字可以使不了解的朋友学会怎样配置和使用Statspack!

下面是正文:

Oracle Statspack 从Oracle8.1.6开始被引入Oracle,并马上成为DBA和Oracle专家用来诊断数据库性能的强有力的工具。通过Statspack我们可以很容易的确定Oracle数据库的瓶颈所在,记录数据库性能状态。因此了解和使用Statspack对于DBA来说至关重要。
在数据库中Statspack的脚本位于$Oracle_HOME/RDBMS/ADMIN目录下,对于Oracle8.1.6,是一组以stat开头的文件;对于Oracle8.1.7,是一组以sp开头的文件。
在Oracle8.1.6中,Statspack第一次发布,但是你也可以在以下链接找到可用于Oracle80~Oracle8.1.5的版本。

http://www.Oracle.com/oramag/Oracle/00-Mar/index.html?o20tun.html
http://www.Oracle.com/oramag/Ora ... tatspack-other.html

在816以前的版本使用Statspack,你需要使用statscbps.sql脚本建立一个v$buffer_pool_statistics视图,该脚本包含在以上链接下载的tar文件中。
访问该链接,你可能需要一个OTN帐号,申请该帐号是免费的。

在Statspack发布之前,我们通常能够使用诊断数据库的工具是两个脚本UTLBSTAT.SQL和UTLESTAT.SQL,BSTAT/ESTAT是一个非常简单的性能诊断工具。UTLBSTAT获得开始时很多V$视图的快照,UTLESTAT通过先前的快照和当前视图生成一个报表。实际上通过这个报表我们很难读出或者解释系统性能方面的问题。Statspack改变了这一切,通过连续的数据收集,Statspack能给我们提供至关重要的趋势分析。这是一个巨大的进步。

下面我们来讲一讲Statspack的安装,配置,使用,解读。

一. 系统参数

为了能够顺利安装和运行Statspack你可能需要设置以下系统参数:
1. job_queue_processes
为了能够建立自动任务,执行数据收集,该参数需要大于0。你可以在初试化参数文件中修改该参数。

2. timed_statistics
收集操作系统的计时信息,这些信息可被用来显示时间等统计信息、优化数据库和 SQL 语句。要防止因从操作系统请求时间而引起的开销,请将该值设置为False。
使用statspack收集统计信息时建议将该值设置为 TRUE,否则收集的统计信息大约只能起到10%的作用,将timed_statistics设置为True所带来的性能影响与好处相比是微不足道的。
该参数使收集的时间信息存储在在V$SESSTATS 和V$SYSSTATS 动态性能视图中。

Timed_statistics参数可以在实例级进行更改

SQL> alter system set timed_statistics = true;
System altered

SQL>

二. 安装Statspack

安装Statspack需要用internal身份登陆,或者拥有SYSDBA(connect / as sysdba)权限的用户登陆。需要在本地安装或者通过telnet登陆到服务器。
在Oracle8.1.6版本中运行statscre.sql;在Oracle8.1.7版本中运行spcreate.sql。

首先登陆到数据库,最好转到$Oracle_HOME/RDBMS/ADMIN目录,这样我们执行脚本就可以方便些。

创建存储数据的表空间,如果采样间隔较短,周期较长,打算长期使用,那么你可能需要一个大一点的表空间,如果每个半个小时采样一次,连续采样一周,数据量是很大的。本例创建一个500M的测试表空间。

三. 测试安装好的Statspack

运行statspack.snap可以产生系统快照,运行两次,然后执行spreport.sql就可以生成一个基于两个时间点的报告。

如果一切正常,说明安装成功。

SQL>execute statspack.snap
PL/SQL procedure successfully completed.
SQL>execute statspack.snap
PL/SQL procedure successfully completed.
SQL>@spreport.sql


可是有可能你会得到以下错误:

SQL> exec statspack.snap;
BEGIN statspack.snap; END;

*
ERROR at line 1:
ORA-01401: inserted value too large for column
ORA-06512: at "PERFSTAT.STATSPACK", line 978
ORA-06512: at "PERFSTAT.STATSPACK", line 1612
ORA-06512: at "PERFSTAT.STATSPACK", line 71
ORA-06512: at line 1


这是Oracle的一个Bug,Bug号1940915。
该Bug自8.1.7.3后修正。
这个问题只会出现在多位的字符集,需要修改spcpkg.sql脚本,$Oracle_HOME/rdbms/admin/spcpkg.sql,将"substr" 修改为 "substrb",然后重新运行该脚本。
该脚本错误部分:

select l_snap_id
, p_dbid
, p_instance_number
, substr(sql_text,1,31)
...........

substr 会将多位的字符, 当作一个byte.substrb 则会当作多个byte。在收集数据时, statpack 会将 top 10 的 sql 前 31 个字节 存入数据表中,若在SQL的前31 个字有中文,就会出现此错误。

四. 规划自动任务

Statspack正确安装以后,我们就可以设置定时任务,开始收集数据了。可以使用spatuo.sql来定义自动任务。
先来看看spauto.sql的关键内容:

dbms_job.submit(:jobno, 'statspack.snap;', trunc(sysdate+1/24,'HH'), 'trunc(SYSDATE+1/24,''HH'')', TRUE, :instno);

这个job任务定义了收集数据的时间间隔:
一天有24个小时,1440分钟,那么:
1/24 HH 每小时一次
1/48 MI 每半小时一次
1/144 MI 每十分钟一次
1/288 MI 每五分钟一次

我们可以修改spauto.sql来更改执行间隔,如:

dbms_job.submit(:jobno, 'statspack.snap;', trunc(sysdate+1/144,'MI'), 'trunc(SYSDATE+1/24,''HH'')', TRUE, :instno);

然后我们执行spauto,这样我们就建立了一个每30分钟执行一次的数据收集计划。你可以查看spauto.lis来获得输出信息:

SQL>
SQL> --
SQL> -- Schedule a snapshot to be run on this instance every hour, on the hour
SQL>
SQL> variable jobno number;
SQL> variable instno number;
SQL> begin
2 select instance_number into :instno from v$instance;
3 dbms_job.submit(:jobno, 'statspack.snap;', trunc(sysdate+1/144,'MI'), 'trunc(SYSDATE+1/144,''MI'')', TRUE, :instno);
4 commit;
5 end;
6 /

PL/SQL 过程已成功完成。

SQL>

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Note that this job number is needed when modifying or removing
the job:

----------
22

Job queue process
~~~~~~~~~~~~~~~~~
Below is the current setting of the job_queue_processes init.ora
parameter - the value for this parameter must be greater
than 0 to use automatic statistics gathering:

3 where job = :jobno;

五. 生成分析报告

调用spreport.sql可以生成分析报告:

The default report file name is sp_1_100. To use this name,

这样就生成了一个报告,可是如果中间停过机,那么你可能收到以下错误信息:

六. 移除定时任务

移除一个定时任务,可以如下操作:

SQL> select job,log_user,priv_user,last_date,next_date,interval from user_jobs;
JOB LOG_USER LAST_DATE NEXT_DATE INTERVAL
---------- ------------------------------ ------------------------------ ------------------------------ ----------- 22 PERFSTAT 2002-12-5:14:33:26 2002-12-5 14:43:00 trunc(SYSDATE+1/144,'MI')
SQL> execute dbms_job.remove('22')

PL/SQL procedure successfully completed

七. 删除历史数据

删除stats$snapshot数据表中的相应数据,其他表中的数据会相应的级连删除:

SQL> select max(snap_id) from stats$snapshot;

MAX(SNAP_ID)
------------
166

SQL> delete from stats$snapshot where snap_id < = 166;

143 rows deleted

你可以更改snap_id的范围以保留你需要的数据。
在以上删除过程中,你可以看到所有相关的表都被锁定。

SQL> select a.object_id,a.Oracle_username ,b.object_name
from v$locked_object a,dba_objects b
where a.object_id = b.object_id
/

八. 调整STATSPACK的收集门限

Statspack有两种类型的收集选项:
级别(level):控制收集数据的类型
门限(threshold):设置收集的数据的阈值。

1.级别(level)
Statspack共有三种快照级别,默认值是5
a.level 0: 一般性能统计。包括等待事件、系统事件、系统统计、回滚段统计、行缓存、SGA、会话、锁、缓冲池统计等等。
b.level 5: 增加SQL语句。除了包括level0的所有内容,还包括SQL语句的收集,收集结果记录在stats$sql_summary中。
c.level 10: 增加子锁存统计。包括level5的所有内容。并且还会将附加的子锁存存入stats$lathc_children中。在使用这个级别时需要慎重,建议在Oracle support的指导下进行。

可以通过statspack包修改缺省的级别设置

SQL>execute statspack.snap(i_snap_level=>0,i_modify_parameter=>’true’);

通过这样的设置,以后的收集级别都将是0级。
如果你只是想本次改变收集级别,可以忽略i_modify_parameter参数。

SQL>execute statspack.snap(i_snap_level=>10);

2.快照门限

快照门限只应用于stats$sql_summary表中获取的SQL语句。
因为每一个快照都会收集很多数据,每一行都代表获取快照时数据库中的一个SQL语句,所以stats$sql_summary很快就会成为Statspack中最大的表。

门限存储在stats$statspack_parameter表中。让我们了结一下各种门限:
a. executions_th 这是SQL语句执行的数量(默认值是100)
b. disk_reads_tn 这是SQL语句执行的磁盘读入数量(默认值是1000)
c. parse_calls_th 这是SQL语句执行的解析调用的数量(默认值是1000)
d. buffer_gets_th 这是SQL语句执行的缓冲区获取的数量(默认值是10000)

任何一个门限值超过以上参数就会产生一条记录。

通过调用statspack.modify_statspack_parameter函数我们可以改变门限的默认值。
例如:
SQL>execute statspack.modify_statspack_parameter(i_buffer_gets_th=>100000,i_disk_reads_th=>100000;
