Exp local Export and imp local import
Exp command:
1 exp username/psw@test file=d:test.dmp full=y
2 exp username/psw@test file=d:test.dmp owner= (ly)
3 exp username/psw@test file= d:test.dmp tables= (GRID1,GRID2)
1 One is the overall export of test (Oracle service name corresponding to a database) database
2 exporting all tables that belong to user ly
3 The table grid1, with GRID2 export
D:test.dmp is the exported file address
IMP command:
1 Imp system/psw@test file=d:test.dmp
2 imp system/psw@test full=y file=d:test.dmp ignore=y
3 imp system/psw@test file=d:test.dmp tables= (grid1) ignore=y indicates that the table is not imported if a table already exists in the database being imported
3 means import only grid1 this table
Test whether the corresponding database is true before importing the export: Tnsping test, the same test is the service name
All commands can be executed under CMD
Remotely manipulate a database with Exp/imp
Remote operation of the Oracle database, assuming that the database is on the 192.168.1.110, the following methods:
First, on the client creation and service-side corresponding service name
Method 1:
modifying Tnsnames.ora files
To join the name of a remote server:
SQL code
TEST_ORCL =
(DESCRIPTION =
(Address_list =
(address = (PROTOCOL = TCP) (HOST = 192.168.1.110) (PORT = 1521))
)
(Connect_data =
(service_name = ORCL)
)
)
Method 2:
On the Oracle client, open Net Manager.
Create a service named TEST_ORCL, host IP: 192.168.1.110, service name ORCL, Port 1521
Second, test whether the remote server is unblocked
After entering cmd, execute command: tnsping TEST_ORCL.
III. Remote Operations Database
Export:
SQL code
1:exp USERNAME/PASSWORD@TEST_ORCL File=bak_filepath
2:exp USERNAME/PASSWORD@TEST_ORCL full=y File=bak_filepath
Username username, password password, TEST_ORCL customer service name, bak_filepath backup files stored path
Import:
SQL code
1:imp USERNAME/PASSWORD@TEST_ORCL File=bak_filepath full=y
2:imp username/password@test_orcl/database_name File=bak_filepath full=y
3:imp USERNAME/PASSWORD@TEST_ORCL File=bak_filepath fromuser=fromadmin touser=toadmin
Username username, password password, TEST_ORCL customer service name, bak_filepath backup files stored path
Fromadmin the user name of the backup data, toadmin the user name of the restored database. database_name restored to that database.
Full=y exports the database as a whole, including the table structure, and so on.
