一、修改資料庫伺服器中listener.ora檔案內容

路徑：

/u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora

# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
    )
  )
ADR_BASE_LISTENER = /u01/app/oracle
 

修改為：

SID_LIST_LISTENER =
    (SID_LIST =
        (SID_DESC =
            (GLOBAL_DBNAME = orcl)
            (ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
            (SID_NAME = orcl)
        )
    )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
    )
  )


ADR_BASE_LISTENER = /u01/app/oracle
 

二、修改資料庫伺服器中tnsnames.ora檔案內容

路徑：

/u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora

# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )
 

修改為：

# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
orcl =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.8.13)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SID = orcl)
    )
  )

三、Windows 2012 R2 Server伺服器自身缺少.net framework 3.5也會導致監聽問題。
