Oracle 数据库监听错误

Question

实际上，昨天工作时，我在 sql developer 中的连接是正常的。今天我无法连接，当我检查我的监听器（LISTENER1）的状态时，它不知何故被终止了。当我尝试启动它时，我收到以下错误消息：

TNSLSNR for 64-bit Windows: Version 11.2.0.1.0 - Production
System parameter file is C:\app\neiral\product\11.2.0\dbhome_1\network\admin\listener.ora
Log messages written to c:\app\neiral\diag\tnslsnr\DESKTOP-BNNHGQO\listener1\alert\log.xml
Error listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.0.78)(PORT=2521)))
TNS-12545: Connect failed because target host or object does not exist
 TNS-12560: TNS:protocol adapter error
  TNS-00515: Connect failed because target host or object does not exist
   64-bit Windows Error: 49: Unknown error

这种情况还发生过一次。不过，我可以通过简单的计算机重启来“修复”它。现在它仍然存在。我的另一个侦听器（我认为是在创建数据库时创建的）启动时没有问题（它的名字是 LISTENER，但它没有出现在 NET 配置助手中。它们会不会相互干扰，因为它们在不同的端口上侦听，所以我无法连接？），而我用来创建连接的侦听器（LISTENER1）无法启动并给出上述错误。

这是“listener.ora”文件

LISTENER1 =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.78)(PORT = 2521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC2521))
    )
  )

SID_LIST_LISTENER1 =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\app\neiral\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\app\neiral\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
  )

ADR_BASE_LISTENER1 = C:\app\neiral

这是“tnsnames.ora”文件

LISTENER_RLLESHI =
  (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.78)(PORT = 2521))


REJNALD =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.78)(PORT = 2521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = rejnald.lleshi)
    )
  )

ORACLR_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC2521))
    )
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
    )
  )

感谢您花时间思考这个问题。
