oracle报错：The Network Adapter could not establish the connection的解决

进入oracle安装目录product11.2.0dbhome_1NETWORKADMIN，修改listener.ora和tnsnames.ora，修改host

我的网络IP为192.168.6.24：

 

listener.ora

# listener.ora Network Configuration File: D:	oolsoracleproduct11.2.0dbhome_1NETWORKADMINlistener.ora

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = D:	oolsoracleproduct11.2.0dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:	oolsoracleproduct11.2.0dbhome_1inoraclr11.dll")
    )
    (SID_DESC = 
        (GLOBAL_DBNAME = ORCL) 
        (ORACLE_HOME = D:	oolsoracleproduct11.2.0dbhome_1) 
        (SID_NAME = ORCL) 
    )
  )
     
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.6.24)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = D:	oolsoracle

tnsnames.ora

# tnsnames.ora Network Configuration File: D:	oolsoracleproduct11.2.0dbhome_1

LISTENER_ORCL =
  (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.6.24)(PORT = 1521))


ORACLR_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
    )
  )

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.6.24)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

 然后，重启以下服务
