Oracle 数据库远程连接问题

我已在Windows计算机上安装了数据库11g。现在我需要从我的应用程序所在的机器B窗口访问该数据库。我可以ping B->A，但telnet不工作。下面是一些供参考的文件

我已经尝试过几件事：

已禁用防火墙。 已使用入站和出站规则打开端口。 已启动服务。 listener.ora

listener.ora Network Configuration File: C:\app\rajhegde\product\11.2.0\dbhome_1\network\admin\listener.ora

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

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS =
        (PROTOCOL = IPC)(KEY = EXTPROC1522)
      )
      (ADDRESS =
        (PROTOCOL = TCP)(HOST = rajhegde-lap2)(PORT = 1522))
      )
    )

    )
    (CONNECT_DATA =

    )
  )

lsnrctl状态的输出

检查防火墙是否未阻止您尝试访问的端口，以及oracle服务是否正常运行，该服务正在侦听端口以进行连接。您尚未说明如何连接，但标记暗示SQL Developer，因此显示您正在使用的连接设置会有所帮助。您正在尝试远程登录到端口1522吗？你能把你的问题格式化以便于阅读吗？但是您的数据库没有向侦听器注册，并且您的listener.ora和tnsnames.ora中的IP不匹配，因此您可能有，并且需要检查/设置local_listener参数？检查Rajegde-lap2解析为什么，并与该设置进行比较，以及您正在使用什么进行连接。此外，请不要
