Oracle Database Import Export DMP file

First ask the table space name and size of the other database, then create the appropriate tablespace in your Oracle, and finally use the command to import and export the data.
Add:
1. To create a new database;

Oracle data import and export imp/exp is equivalent to Oracle data restore and backup. The EXP command can be

To export data from the remote database server to a local DMP file, the IMP command can take the DMP file from the

To a remote database server. With this feature you can build two identical databases, one

one for testing and one for formal use.
example: Imp command import data:
imp username/[email  Protected] File=xxx.dmp fromuser=xxx touser=xxx tables= (xxx,xxx)

fromuser If the table space is multiple, use () to enclose it: fromuser= (A, B),
touser parameter Imitation fromuser parameter;
data export:
1 full export of database test, user Name System Password Manager Export to D:\daochu.dmp
[email protected]  file=d:\daochu.dmp full=y

2 Exporting the system user in the database to the SYS user's table
Exp system/[email protected] file=d:\daochu.dmp owner= (System,sys)

3 Exporting Tables Inner_notify, Notify_staff_relat in the database
Exp aichannel/[email protected] file= d:\data\newsmgnt.dmp tables=

(Inner_notify,notify_staff_relat)

import of data
1 Import data from D:\daochu.dmp Test database.
   imp system/[email protected]  file=d:\daochu.dmp
   imp aichannel/[email protected]  full=y file=file= d:\data\newsmgnt.dmp

Ignore=y
There may be a problem, because some tables already exist, and then it will error, the table will not be guided

Into.
Add Ignore=y to the back.

2 the table table1 in D:\daochu.dmp into
imp system/[email protected]  file=d:\daochu.dmp tables= (table1)  

Basically the above import and export is enough. In many cases, you must first delete the table and then import it.

note:
The database can be connected. You can use tnsping test to get the database test to connect.

Appendix I:
First, start SQL*PULS
Second, System/manager landed
Third, create user username identified by password (if you have already created a user, this step

can be omitted)
IV, GRANT CREATE user,drop user,alter USER, create any VIEW,
   DROP any view,exp_full_database,imp_full_database,
       dba,connect,resource,create SESSION to User name  
      Imp userid=system/ Manager full=y file=*.dmp
      or Imp userid=system/ Manager Full=y File=filename.dmp

Example execution:
F:\work\oracle_data\backup>imp userid=test/test full=y

File=inner_notify.dmp
