本文介绍了当遇到Oracle数据库未Mount的问题时的两种解决方法：一是通过修改listener.ora文件中的参数，二是通过修改tnsnames.ora文件中的参数，并提供了具体的步骤指导。

一般出现这个问题可能是因为你的数据库没有Mount 解决方案：

1，可以通过修改listener.ora（该文件位于:{你的Oracle安装盘}:\app\administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN）的参数,把动态的参数设置为静态的参数,红色标注部分,然后从新启动监听,就OK

SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = C:\oracle\product\10.1.0\db_1)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = 数据库实例名)
      (ORACLE_HOME = c:\oracle\product\10.1.0\db_1)
      (SID_NAME = 数据库实例名)
    )
)
LISTENER =
(DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = lypch )(PORT = 1521))
      )
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
      )
    )
)

2，也可以通过修改tnsnames.ora文件（该文件位于:{你的Oracle安装盘}:\app\administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN）的参数,红色表注部分

# tnsnames.ora Network Configuration File: C:\oracle\product\10.1.0\db_1
\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.
AMMICLY =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = lypch )(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = ammicly)
      (UR=A)
    )
)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
)
然后 sqlplus /nolog
SQL>alter database mount;
SQL>alter database open;
