年末整理四 oracle tns 地址

oracle 客户端连接远程oracle的数据源配置，在
oracle9i:　　oracle9/network/admin/tnsnames.ora
oracle10g:   D:\oracle\product\10.2.0\client_1\NETWORK\ADMIN\tnsnames.ora

例如：
10g：
CONTRACT =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.100.42)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SID = sinocrm2)
      (SERVER = DEDICATED)
    )
  )
 
9i:
test1=
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.60.59)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = test1)
    )
  )
