Oracle怎樣部署Statspack并生成報告，針對這個問題，這篇文章詳細介紹了相對應的分析和解答，希望可以幫助更多想解決這個問題的小伙伴找到更簡單易行的方法。

Oracle 部署 Statspack

[實驗環境]
操作系統 RedHat 5.5
主機名 lxh
數據庫版本 Oracle 10.2.0
字符集 GHS16GBK
生產庫實例名 prod

[實驗過程]
1.部署statspack

1.1、創建一個專門用于statspack的表空間statspack

SYS@ prod>create tablespace statspack datafile '/u01/app/oracle/oradata/prod/statspack01.dbf' size 300m;

1.2、以sysdba身份執行創建prefstat對象的腳本
SYS@ prod>@?/rdbms/admin/spcreate.sql
Choose the PERFSTAT user's password
-----------------------------------
Not specifying a password will result in the installation FAILING

Enter value for perfstat_password:oracle
oracle
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
------------------------------ --------- ----------------------------
EXAMPLE                        PERMANENT
STATSPACK                      PERMANENT
SYSAUX                         PERMANENT *
TBS1                           PERMANENT
TEST3                          PERMANENT
USERS                          PERMANENT

Pressing <return> will result in STATSPACK's recommended default
tablespace (identified by *) being used.

Enter value for default_tablespace:statspack
Using tablespace STATSPACK 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 <return> will result in the database's default Temporary
tablespace (identified by *) being used.
Enter value for temporary_tablespace:回車
… …

SPCPKG complete. Please check spcpkg.lis for any errors.
PERFSTAT@ prod>

Statstack安裝完成。

1.3、設置statspack自動產生快照的間隔時間為15分鐘

[oracle@James ~]$vi /u01/app/oracle/product/10.2.0/db_1/rdbms/admin/spauto.sql
variable jobno number;
variable instno number;
begin
 select instance_number into :instno from v$instance;
 dbms_job.submit(:jobno, 'statspack.snap;',trunc(sysdate+1/96,'MI'), 'trunc(SYSDATE+1/96,''MI'')', TRUE, :instno);
 commit;
end;
/
1.4、設置快照的默認級別為7級

SYS@ prod>exec statspack.modify_statspack_parameter(i_snap_level=>7);


2.產生statspack報告

2.1、啟動statspack的自動快照

SCOTT@ prod>conn perfstat/oracle
PERFSTAT@ prod>@?/rdbms/admin/spauto

2.2、驗證statspack自動生成的報告

PERFSTAT@prod>alter session set nls_date_format='yyyy-mm-dd hh34:mi:ss';
PERFSTAT@prod>select snap_id,snap_time,snap_level from stats$snapshot order by snap_time;

  SNAP_ID SNAP_TIME           SNAP_LEVEL
---------- ------------------- ----------
        1 2014-08-25 17:52:02          7
        2 2014-08-25 19:05:03          7
        3 2014-08-25 19:20:04          7
        4 2014-08-25 19:35:05          7
        5 2014-08-25 19:50:05          7
        6 2014-08-25 20:05:01          7

2.3、生成statspack分析報告
SQL>@?/rdbms/admin/spreport

Current Instance
~~~~~~~~~~~~~~~~
  DB Id    DB Name      Inst Num Instance
----------- ------------ -------- ------------
 199802235 PROD                1 prod
Instances in this Statspack schema
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  DB Id    Inst Num DB Name      Instance     Host
----------- -------- ------------ ------------ ------------
 199802235        1 PROD         prod         lxh

Using  199802235 for database Id
Using          1 for instance number
Specify the number of days of snapshots to choose from
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Entering the number of days (n) will result in the most recent
(n) days of snapshots being listed.  Pressing <return> without
specifying a number lists all completed snapshots.
Listing all Completed Snapshots
                                                      Snap
Instance     DB Name        Snap Id   Snap Started    Level Comment
------------ ------------ --------- ----------------- ----- --------------------
prod         PROD                 1 25 Aug 2014 17:52     7

                                 2 25 Aug 2014 19:05     7
                                 3 25 Aug 2014 19:20     7
                                 4 25 Aug 2014 19:35     7
                                 5 25 Aug 2014 19:50     7
                                 6 25 Aug 2014 20:05     7
Specify the Begin and End Snapshot Ids
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Enter value for begin_snap:2
Enter value for end_snap: 3
Enter value for report_name:

@?/rdbms/admin/spreport

Specify the Begin and End Snapshot Ids
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Enter value for begin_snap: 3
Enter value for end_snap: 4
Enter value for report_name:

Specify the Begin and End Snapshot Ids
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Enter value for begin_snap: 4
Enter value for end_snap: 5
Enter value for report_name:

Specify the Begin and End Snapshot Ids
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Enter value for begin_snap: 5
Enter value for end_snap: 6
Enter value for report_name:

2.4、取消statspack自動生成快照
查看job ID
PERFSTAT@ prod>select job,log_user,last_date,next_date from user_jobs;

      JOB LOG_USER                       LAST_DATE           NEXT_DATE
---------- ------------------------------ ------------------- -------------------
       22 PERFSTAT                       2014-08-25 20:05:01 2014-08-25 20:20:00

PERFSTAT@ prod>exec dbms_job.remove('22');
