AWR导入分析数据
有些时候，我们分析客户的数据库的性能，需要请客户将AWR数据导出，然后导入本机数据库进行分析。
一、在导入数据之前，一般需要创建以下路径
DATA_FILE_DIR
DATA_PUMP_DIR
EXP
IMP
SQL> create directory data_file_dir as 'd:\dir'; --将要导入的dmp文件存到此路径下
SQL> create directory exp as 'd:\exp';
SQL> create directory exp as 'd:\exp';
SQL> create directory data_pump_dir as 'd:\dpdump';
create directory data_pump_dir as 'd:\dpdump'
*
第 1 行出现错误:
ORA-00955: 名称已由现有对象使用
data_pump_dir 这个路径数据库已经有了，就不用创建啦。
二、导入
SQL> @?/RDBMS/ADMIN/AWRLOAD --执行awrload脚本
~~~~~~~~~~
AWR LOAD
~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~ This script will load the AWR data from a dump file. The ~
~ script will prompt users for the following information: ~
~ (1) name of directory object ~
~ (2) name of dump file ~
~ (3) staging schema name to load AWR data into ~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Specify the Directory Name
~~~~~~~~~~~~~~~~~~~~~~~~~~
Directory Name Directory Path
------------------------------ -------------------------------------------------
DATA_FILE_DIR D:\dir
DATA_PUMP_DIR D:\oracle\admin\stream\dpdump\
EXP d:\exp
IMP d:\imp
ORACLECLRDIR D:\oracle\product\11.2.0\dbhome_1\bin\clr
ORACLE_OCM_CONFIG_DIR D:\oracle\product\11.2.0\dbhome_1\ccr\state
XMLDIR D:\oracle\product\11.2.0\dbhome_1\rdbms\xml
Choose a Directory Name from the list above (case-sensitive).
输入 directory_name 的值: DATA_FILE_DIR ----输入dmp文件保存的路径名字注意一定要大写
Using the dump directory: DATA_FILE_DIR
Specify the Name of the Dump File to Load
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Please specify the prefix of the dump file (.dmp) to load:
输入 file_name 的值: awrdat_50063_50209_20110622 ---输入dmp文件的名字，不写后缀，否则报错
Loading from the file name: awrdat_50063_50209_20110622.dmp
Staging Schema to Load AWR Snapshot Data
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The next step is to create the staging schema
where the AWR snapshot data will be loaded.
After loading the data into the staging schema,
the data will be transferred into the AWR tables
in the SYS schema.
The default staging schema name is AWR_STAGE.
To use this name, press <return> to continue, otherwise enter
an alternative.
输入 schema_name 的值: AWR_STAGE
Using the staging schema name: AWR_STAGE
Choose the Default tablespace for the AWR_STAGE user
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Choose the AWR_STAGE users's default tablespace. This is the
tablespace in which the AWR data will be staged.
TABLESPACE_NAME CONTENTS DEFAULT TABLESPACE
------------------------------ --------- ------------------
SYSAUX PERMANENT *
USERS PERMANENT
Pressing <return> will result in the recommended default
tablespace (identified by *) being used.
输入 default_tablespace 的值: USERS --输入导入的数据存放的表空间名字
Using tablespace USERS as the default tablespace for the AWR_STAGE
Choose the Temporary tablespace for the AWR_STAGE user
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Choose the AWR_STAGE user's temporary tablespace.
TABLESPACE_NAME CONTENTS DEFAULT TEMP TABLESPACE
------------------------------ --------- -----------------------
TEMP TEMPORARY *
Pressing <return> will result in the database's default temporary
tablespace (identified by *) being used.
输入 temporary_tablespace 的值: TEMP --输入临时表空间的名字
Using tablespace TEMP as the temporary tablespace for AWR_STAGE
... Creating AWR_STAGE user
|
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| Loading the AWR data from the following
| directory/file:
| D:\dir
| awrdat_50063_50209_20110622.dmp
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
| *** AWR Load Started ...
|
| This operation will take a few moments. The
| progress of the AWR load operation can be
| monitored in the following directory/file:
| D:\dir
| awrdat_50063_50209_20110622.log
|
... Dropping AWR_STAGE user
End of AWR Load

导入成功。

四、验证导入信息
可以通过查看dba_hist_snap表来验证导入的snap信息：
SQL> select snap_id, dbid, instance_number, to_char(begin_interval_time, 'yyyy-m
m-dd hh24:mi:ss.ff')from dba_hist_snapshot where dbid = 2400249746 order by 1, 3;
SNAP_ID DBID INSTANCE_NUMBER TO_CHAR(BEGIN_INTERVAL_TIME,'
