Oracle 无法通过IP连接问题

1.安装目录:D:\app\Administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN

2.listener.ora(里面的localhost或127.0.0.1改成机器名)

# listener.ora Network Configuration File: D:\app\Administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora# Generated by Oracle configuration tools.SID_LIST_LISTENER =  (SID_LIST =    (SID_DESC =      (SID_NAME = CLRExtProc)      (ORACLE_HOME = D:\app\Administrator\product\11.2.0\dbhome_1)      (PROGRAM = extproc)      (ENVS = "EXTPROC_DLLS=ONLY:D:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll")    )  )LISTENER =  (DESCRIPTION_LIST =    (DESCRIPTION =      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))    )    (DESCRIPTION =      (ADDRESS = (PROTOCOL = TCP)(HOST = 改成机器名)(PORT = 1521))    )  )ADR_BASE_LISTENER = D:\app\Administrator

3. sqlnet.ora (参考下,不用该)

# sqlnet.ora Network Configuration File: D:\app\Administrator\product\11.2.0\dbhome_1\network\admin\sqlnet.ora# Generated by Oracle configuration tools.# This file is actually generated by netca. But if customers choose to # install "Software Only", this file wont exist and without the native # authentication, they will not be able to connect to the database on NT.SQLNET.AUTHENTICATION_SERVICES= (NTS)NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

4.tnsnames.ora(里面的localhost或127.0.0.1改成机器名)

# tnsnames.ora Network Configuration File: D:\app\Administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN\tnsnames.ora# Generated by Oracle configuration tools.ORACLR_CONNECTION_DATA =  (DESCRIPTION =    (ADDRESS_LIST =      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))    )    (CONNECT_DATA =      (SID = CLRExtProc)      (PRESENTATION = RO)    )  )LISTENER_ORCL =  (ADDRESS = (PROTOCOL = TCP)(HOST = 机器名)(PORT = 1521))ORCL =  (DESCRIPTION =    (ADDRESS_LIST =      (ADDRESS = (PROTOCOL = TCP)(HOST = 机器名)(PORT = 1521))    )    (CONNECT_DATA =      (SERVER = DEDICATED)      (SERVICE_NAME = orcl)    )  )
