1.安装Statspack工具(statspack工具的脚本在$ORACLE_HOME/rdbms/admin目录下,全是以sp开头的文件)

[oracle@oracle ~]$ sqlplus / as sysdba

sql> select file_name,tablespace_name from dba_data_files;

FILE_NAMETABLESPACE_NAME

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

/home/oracle/app/oradata/orcl/users01.dbf USERS

/home/oracle/app/oradata/orcl/undotbs01.dbf UNDOTBS1

/home/oracle/app/oradata/orcl/sysaux01.dbf SYSAUX

/home/oracle/app/oradata/orcl/system01.dbf SYSTEM

/home/oracle/app/oradata/orcl/tong.dbf TONG1

6 rows selected.

sql> create tablespace perfstat datafile '/home/oracle/app/oradata/orcl/perfstat.dbf' size 200M; --创建独立的表空间存储statspack数据

Tablespace created.

sql>@ /home/oracle/app/product/11.2.0/dbhome_1/rdbms/admin/spcreate.sql --执行安装statspack脚本文件,会提示输入perfstat用户的密码,默认表空间,临时表空间

sql>

2.使用statspack用户登陆,生成数据

sql> conn perfstat/system

Connected.

sql> execute statspack.snap;

PL/sql procedure successfully completed. --执行快照获取数据(多执行几次)

sql> execute statspack.snap;

PL/sql procedure successfully completed.

sql> execute statspack.snap;

PL/sql procedure successfully completed.

sql> execute statspack.snap;

PL/sql procedure successfully completed.

sql> select max(snap_id) from stats$snapshot; --查看有多少个报告

MAX(SNAP_ID)

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

4

sql> @ /home/oracle/app/product/11.2.0/dbhome_1/rdbms/admin/spreport.sql --生成报告

sql> exit

Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production

With the Partitioning,OLAP,Data Mining and Real Application Testing options

[oracle@oracle admin]$ vim sp_1_4.lst --查看statspack中的信息

3.statspack管理

sql> @ /home/oracle/app/product/11.2.0/dbhome_1/rdbms/admin/sppurge.sql --删除历史数据

sql> @ /home/oracle/app/product/11.2.0/dbhome_1/rdbms/admin/sptrunc.sql --清空表中的数据

sql> @ /home/oracle/app/product/11.2.0/dbhome_1/rdbms/admin/spdrop.sql --卸载statspack工具
