Statspack 安装和使用

原创: 2016-06-07 17:28:24 782浏览

使用Statspack的性能采集是通过快照的方式实现的，即Statspack在某一个时间点对系统的性能数据做一个快照，并将快照保存在perfst

perfcreate

使用sys用户连接数据库，并运行spcreate.sql脚本，，首先要先输入新建用户perfstat的密码，我们输入的密码是perfcreate。

Choose the Default tablespace for the PERFSTAT user

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

Below is the list of online tablespaces in this database which can

store user data. Specifying the SYSTEM tablespace for the user's

default tablespace will result in the installation FAILING, as

using SYSTEM for performance data is not supported.

Choose the PERFSTAT users's default tablespace. This is the tablespace

in which the STATSPACK tables and indexes will be created.

TABLESPACE_NAME CONTENTS STATSPACK DEFAULT TABLESPACE

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

CW PERMANENT

CW_MD PERMANENT

CW_PART PERMANENT

DBAPI PERMANENT

PETDOG PERMANENT

SEVEN PERMANENT

STRMADMIN PERMANENT

SYSAUX PERMANENT *

USERS PERMANENT

Pressing will result in STATSPACK's recommended default

tablespace (identified by *) being used.

输入 default_tablespace 的值: users

接下来Oracle列出了数据库中可以使用的表空间，要求我们为用户perfstat指定默认表空间，也就是之后储存Statspack信息的表空间，这里我们选择users表空间。

Using tablespace USERS as PERFSTAT default tablespace.

Choose the Temporary tablespace for the PERFSTAT user
-----------------------------------------------------
Below is the list of online tablespaces in this database which can
store temporary data (e.g. for sort workareas). Specifying the SYSTEM
tablespace for the user's temporary tablespace will result in the
installation FAILING, as using SYSTEM for workareas is not supported.

Choose the PERFSTAT user's Temporary tablespace.

TABLESPACE_NAME CONTENTS DB DEFAULT TEMP TABLESPACE
------------------------------ --------- --------------------------
TEMP TEMPORARY *

Pressing will result in the database's default Temporary
tablespace (identified by *) being used.

输入 temporary_tablespace 的值: temp

接着，输入默认临时表空间，毫无疑问，我们选择temp表空间。

下面就是创建perfstat用户对象的操作：

If this script is automatically called from spcreate (which is

the supported method), all STATSPACK segments will be created in

the PERFSTAT user's default tablespace.
