Oacle实现不同机子间导入导出数据

实现一个功能即从本地Oracle导出数据表，文件名为.dmp，然后将该dmp文件导入到另一台主机的oracle表中。感受颇深。主要还是不了解oracle各文件的作用。

首先要更改tnsnames.ora(oracle安装目录中D:\oracle\product\10.2.0\db_1\NETWORK\ADMIN\tnsnames.ora)文件内容：

  ORA10G =                                   //本地oracle标识（文件已有内容）
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 10.10.10.10)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = ora10g)
    )
  )
ORA10G2 =                               //***远程电脑oracle标识（需添加的）***
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 10.3.43.130)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = ora10g)
    )
  )
EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    )
    (CONNECT_DATA =
      (SID = PL***tProc)
      (PRESENTATION = RO)
    )
  )
 
通过导入导出命令：
exp ckkh/ckkh@ora10g file= c:\datanewsmgnt.dmp tables=(ckkh_account,ckkh_account_tmp)
//将本地标识为ora10g的数据库的表数据导出到c盘
imp ckkh/ckkh@ora10g2 file=c:\datanewsmgnt.dmp full=y
//将导出的dmp文件导入到标识为ora10g2的数据库中。
