Export / import tablespace with all objects (datas, users, roles)

Question

Hi, i have a problem or question to the topic export / import tablespace.
On the one hand, i have a database 10g (A) and on the other hand, a database 11g (B).
On A there is a tablespace called PRO.
Furthermore 3 Users:
PRO_Main - contains the datas - Tablespace PRO
PRO_Users1 with a role PRO_UROLE - Tablespace PRO
PRO_Users2 with a role PRO_UROLE - Tablespace PRO
Now, i want to transfer the whole tablespace PRO (included users PRO_MAIN, PRO_USER1, PRO_User2 and the role PRO_UROLE) from A to B.
On B, I 've created the user PRO_Main and the tablespace PRO.
On A , i execute following statement:
expdp PRO_Main/XXX TABLESPACES=PRO DIRECTORY=backup_datapump DUMPFILE=TSpro.dmp LOGFILE=TSpro.log
On B:
impdp PRO_Main/XXX TABLESPACES=PRO DIRECTORY=backup_datapump DUMPFILE=TSpro.dmp LOGFILE=TSpro.log
Result:
The User PRO_Main was imported with all the datas.
But i 'm missing PRO_USER1, PRO_User2 and the role PRO_UROLE...
I assume, i 've used wrong parameters in my expd and / or impdp.
It would be nice, if anybody can give me a hint.
Thanks in advance.
Best Regards,
Frank

When you do a TABLESPACE mode export by specifying just the tablespaces, then all that gets exported are the tables and their dependent objects. The users, roles, and the tablespace definitions themselves don't get exported.
When you do a SCHEMA mode export by specifying the schemas, you will get the schema definitions (if the schema running the export is privied) and all of the objects that the schema owns. The schema does not own roles or tablespace definitions.
In your case, you want to move
1. schemas - which you already created 1 on your target database
2. roles
3. everything in the tablespaces owned by multiple schemas.
There is no 1 export/import command that will do this. This is how i would do this:
1 - move the schema definitions
a. you can either create these manually or
b1. expdp schemas=<your list of schemas> include=user
b2 impdp the results from b1.
2. move the roles
expdp full=y include=role ...
remember, this will include all roles. If you want to limit what gets exported, then use:
include=role:"in ('ROLE1', 'ROLE2', ETC.)
impdo the roles just exported
3. move the user information
a. If you want to move all of the schema's objects like functions, packages, etc, then you need to use a schema mode
export
expdp user/password schemas=a,b,c ...
b. If you want to move only the objects in those tablespaces, then use the tablespace export
expdp user/password tablespaces=tbs1, tbs2, ...
c. import the dumpfile generated in step 3
impdp user/password ...
Hope this helps.
