在Oracle OLAP中，Analytic workspace的概念有点类似与数据库中的schema，也是一组相关对象的集合。但是Analytic workspace会使用一个名为aw$name的table来实际的存储analytic workspace中的对象(dimension,cube,level,attribute等)。有时候，我们可能需要将一个analytic workspace从一个系统迁移到另外一个系统，也可能需要将一个analytic workspace的内容迁移到另外一个analytic workspace中，利用Analytic Workspace Manager可以在图形界面下完成该任务，首先将一个aw导出为EIF文件，然后将EIF导入到另外一个aw即可。
除了awm，也可以通过dbms_aw包来实现同样的功能。
1.版本
GLOBAL@ning>select * from v$version;
BANNER
—————————————————————-
Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 – Prod
PL/SQL Release 10.2.0.3.0 – Production
CORE 10.2.0.3.0 Production
TNS for 32-bit Windows: Version 10.2.0.3.0 – Production
NLSRTL Version 10.2.0.3.0 – Production
2.创建一个directory并授权
SYS@ning>create directory dir_aw as ‘d:\’;
Directory created.
SYS@ning>grant read,write on directory dir_aw to global;
Grant succeeded.
3.将名为global的aw导出为EIF文件
SYS@ning>conn global/global
Connected.
GLOBAL@ning>set serveroutput on
–首先attach该aw
GLOBAL@ning>exec dbms_aw.execute(‘aw attach global’);
IMPORTANT: Analytic workspace GLOBAL is read-only. Therefore, you will not be
able to use the UPDATE command to save changes to it.
PL/SQL procedure successfully completed.
–将当前目录设置为dir_aw
GLOBAL@ning>exec dbms_aw.execute(‘CDA DIR_AW’);
The current directory is DIR_AW.
PL/SQL procedure successfully completed.
–导出为EIF文件
GLOBAL@ning>exec dbms_aw.execute(‘EXPORT ALL TO EIF FILE ”GLOBAL.EIF” NOTEMPDATA’);
PL/SQL procedure successfully completed.
–Detach该aw
GLOBAL@ning>exec dbms_aw.execute(‘AW DETACH global’);
PL/SQL procedure successfully completed.
4.导入EIF文件为已经存在的AW中
–首先以RW模式attach欲导入的aw
GLOBAL@ning>exec dbms_aw.execute(‘AW ATTACH global RW’)
PL/SQL procedure successfully completed.
–将当前目录设置为dir_aw
GLOBAL@ning>exec dbms_aw.execute(‘CDA DIR_AW’);
The current directory is DIR_AW.
PL/SQL procedure successfully completed.
–导入EIF文件到已经存在的aw
GLOBAL@ning>exec dbms_aw.execute(‘IMPORT ALL FROM EIF FILE ”globaL.eif” UPDATE’);
PL/SQL procedure successfully completed.
–Detach该aw
GLOBAL@ning>exec dbms_aw.execute(‘AW DETACH GLOBAL’);
PL/SQL procedure successfully completed.
GLOBAL@ning>commit;
Commit complete.
5.导入EIF文件为新的aw
–创建新的aw
GLOBAL@ning>exec dbms_aw.execute(‘aw create global_new’);
PL/SQL procedure successfully completed.
–设置当前目录
GLOBAL@ning>exec dbms_aw.execute(‘CDA DIR_AW’);
The current directory is DIR_AW.
PL/SQL procedure successfully completed.
–导入EIF文件到已经存在的aw
GLOBAL@ning>exec dbms_aw.execute(‘IMPORT ALL FROM EIF FILE ”globaL.eif” UPDATE’);
PL/SQL procedure successfully completed.
–Detach该aw
GLOBAL@ning>exec dbms_aw.execute(‘AW DETACH GLOBAL’);
PL/SQL procedure successfully completed.
GLOBAL@ning>commit;
Commit complete.
–查看系统中所有的aw
GLOBAL@ning>exec dbms_aw.execute(‘aw list’);
GLOBAL_NEW* R/W UNCHANGED GLOBAL.GLOBAL_NEW
GLOBAL R/W UNCHANGED GLOBAL.GLOBAL
EXPRESS R/O UNCHANGED SYS.EXPRESS
