expdp/impdp 參數network_link使用測試

下面是network_link常用的三個環境測試

1，伺服器端的資料匯出到指定的用戶端

2，不同資料庫間遷移資料。

3，同一個資料庫中不同使用者之間遷移資料。

一：伺服器端的資料匯出到指定的用戶端

1，修改用戶端的TNSNAMES檔案
POWER1 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.111.13)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = power1)
    )
  )
2，建立dblink
SQL> CREATE PUBLIC DATABASE LINK "POWER1"
  2  CONNECT TO scott
  3  IDENTIFIED BY "Oracle"
  4  USING 'POWER1';
 
Database link created.
 
SQL> select * from dual@power1;
 
D
-
X
3，directory目錄
SQL> set lines 170
SQL> col owner for a15
SQL> col directory_name for a60
SQL>  col directory_name for a30
SQL> col DIRECTORY_PATH for a70
SQL> select * from dba_directories;
 
OWNER          DIRECTORY_NAME                DIRECTORY_PATH
--------------- ------------------------------ ----------------------------------------------------------------------
SYS            DUMP                          /tmp
SYS            TOAD_BDUMP_DIR                /u01/app/oracle/diag/rdbms/orcl11g/orcl11g/trace
SYS            XMLDIR                        /u01/app/oracle/product/11.2/db_1/rdbms/xml
SYS            DATA_PUMP_DIR                  /u01/app/oracle/admin/orcl11g/dpdump/
SYS            ORACLE_OCM_CONFIG_DIR          /u01/app/oracle/product/11.2/db_1/ccr/state
如果不存在使用create directory建立再用grant授予使用者權限
4，導資料
[oracle11g@rhel4 admin]$ expdp system/oracle directory=dump dumpfile=scott_test.dmp logfile=scott_log.dmp  network_link='power1' schemas=scott

grant這個命令要在源端資料庫上面執行
SQL> GRANT exp_full_database TO scott; 
 
Grant succeeded.
回到用戶端上面
[oracle11g@rhel4 admin]$ expdp system/oracle directory=dump dumpfile=scott_test.dmp logfile=scott_log.dmp  network_link='power1' schemas=scott
