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)
------------

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

[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
