求教！linux下Oracle访问出错

fantasyERIC

用php网页连接oracle，可以在本机上连接，可是在其他机器上连时出现如下错误：
[unixODBC][Easysoft][Oracle]TNS: Could not resolve TARGETDB parameter as service name, SQL state 08001 in SQLConnect
我的tnsname.ora,listener.ora和sqlnet.ora文件内容如下：
tnsname.ora:
# TNSNAMES.ORA Network Configuration File: /opt/oracle/product/9.2.0/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

KEJIE =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 211.91.230.4(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = kejie)
    )
  )

EXTPROC_CONNECTION_DATA.LOCALDOMAIN =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
    )
    (CONNECT_DATA =

      (PRESENTATION = RO)

      )
