Oacle實(shí)現(xiàn)不同機(jī)子間導(dǎo)入導(dǎo)出數(shù)據(jù)

實(shí)現(xiàn)一個(gè)功能即從本地Oracle導(dǎo)出數(shù)據(jù)表，文件名為.dmp，然后將該dmp文件導(dǎo)入到另一臺主機(jī)的oracle表中。感受頗深。主要還是不了解oracle各文件的作用。

首先要更改tnsnames.ora(Oracle安裝目錄中D:\oracle\product\10.2.0\db_1\NETWORK\ADMIN\tnsnames.ora)文件內(nèi)容：

ORA10G =                                   //本地Oracle標(biāo)識（文件已有內(nèi)容）
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 10.10.10.10)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = ora10g)
    )
)
ORA10G2 =                               //***遠(yuǎn)程電腦Oracle標(biāo)識（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)
    )
)

通過導(dǎo)入導(dǎo)出命令：
exp ckkh/ckkh@ora10g file= c:\datanewsmgnt.dmp tables=(ckkh_account,ckkh_account_tmp)
//將本地標(biāo)識為ora10g的數(shù)據(jù)庫的表數(shù)據(jù)導(dǎo)出到c盤
imp ckkh/ckkh@ora10g2 file=c:\datanewsmgnt.dmp full=y
//將導(dǎo)出的dmp文件導(dǎo)入到標(biāo)識為ora10g2的數(shù)據(jù)庫中。
