部署statspack工具（一）

禁用sga自动管理机制，分配比较小的数据缓冲区(30m)和共享池(70m)空间

1.1关闭SGA自动管理机制

查看是否开启了ASSM

idle>show
parameter sga;

NAME TYPE VALUE

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

lock_sga boolean FALSE

pre_page_sga boolean FALSE

sga_max_size big integer 804M

sga_target big integer 500M

关闭sga自动管理机制：(部分参数重启数据库生效)

sys@TESTDB12>alter
system set memory_target=0;

idle>alter
system set sga_target=0;

idle>show
parameter memory;

NAME TYPE VALUE

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

hi_shared_memory_address integer 0

memory_max_target big integer 804M

memory_target big integer 0

shared_memory_address integer 0

idle>show
parameter sga;

NAME TYPE VALUE

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

lock_sga boolean FALSE

pre_page_sga boolean FALSE

sga_max_size big integer 804M

sga_target big integer 0

1.2设置数据缓冲区的大小为30m

idle>alter
system set db_cache_size=30m;

System
altered.

1.3 设置共享池的大小为70m

idle>alter
system set shared_pool_size=70m scope=spfile;

System
altered.

1.4 验证设置好的数据缓冲区和共享池的大小

idle>show
parameter db_cache_size;

NAME TYPE VALUE

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

db_cache_size big integer 32M

idle>show
parameter shared_pool_size;

NAME TYPE VALUE

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

shared_pool_size big integer 72M

sys@TESTDB12>select
component,current_size/1024/1024 from v$sga_dynamic_components;

2.部署statspack

2.1创建一个专门用于statspack的表空间tools

idle>create
tablespace tools

2
datafile '/u01/app/oracle/oradata/TestDB12/tools01.dbf'

3 size
300m;

Tablespace
created.

2.2以sysdba身份执行创建prefstat对象的脚本

SQL> @?/rdbms/admin/spcreate.sql
/sppurge.sql是删除快照

Choose the PERFSTAT user's password

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

Not specifying a password will result in the
installation FAILING

Enter value for
perfstat_password: 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

SYSAUX PERMANENT *

TOOLS PERMANENT

USERS PERMANENT

Pressing <return> will result in STATSPACK's
recommended default

tablespace (identified by *) being used.

Enter value for
default_tablespace: tools

Using tablespace TOOLS 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:回车

… …

NOTE:

SPCPKG complete. Please check spcpkg.lis for any
errors.

Statstack安装完成。

2.3设置statspack自动产生快照的间隔时间为15分钟（一天有24小时96个15分钟）

{oracle@Redhat55.cuug.net:/u01/app/oracle/product/11.2.0/dbhome_1/rdbms/admin}$
vi /u01/app/oracle/product/11.2.0/dbhome_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/,',''MI'')',
TRUE, :instno);

commit;

end;

2.4设置快照的默认级别为7级

perfstat@TESTDB12>exec
statspack.modify_statspack_parameter(i_snap_level=>7);

PL/SQL procedure successfully completed.

创建序列

sys@TESTDB12>alter
user scott identified by tiger;

User
altered.

sys@TESTDB12>conn
scott/tiger;

Connected.

scott@TESTDB12>CREATE
SEQUENCE emp2_empno

2
INCREMENT BY 1

3
START WITH 1

4
MAXVALUE 100000000

5
CACHE 10000

6
NOCYCLE;

Sequence
created.

3搭建查询环境

3.1创建新表并插入数据

scott@TESTDB12>create
table emp2 as select * from emp where 1=2;

Table
created.

scott@TESTDB12>alter
table emp2 modify empno number(10);

Table
altered.

scott@TESTDB12>alter
table emp2 modify ename varchar(30);

Table
altered.

将emp2 表设为nologging

scott@TESTDB12>alter
table emp2 nologging;

Table
altered.

插入2千万行数据：

scott@TESTDB12>begin

2 for
i in 1..20000000 loop

3
insert into emp2

4
values
(emp2_empno.nextval,'cuug'||i,'SALESMAN',7698,sysdate,1600,300,30);

5 if
mod(i,1000)=0 then

6
commit;

7 end
if;

8 end
loop;

9
commit;

10 end;

11 /

3.2编写查询业务脚本

{oracle@Redhat55.cuug.net:/home/oracle}$
mkdir -p script/bin/

{oracle@Redhat55.cuug.net:/home/oracle/script/bin}$ vi script/bin/share_pool_sql_1.sh

#!/bin/bash

CNT=1

while
[ $CNT -lt 20000000 ]

sqlplus
scott/tiger <<EOF

select
* from emp2 where empno=$CNT;

exit

EOF

CNT=`expr
$CNT + 1`

done

4.运行查询业务脚本并产生statspack报告

4.1运行查询业务脚本并启动statspack的自动快照

{oracle@Redhat55.cuug.net:/home/oracle/script/bin}$
sh share_pool_sql_1.sh

sys@TESTDB12>conn
perfstat/oracle

Connected.
