# listener.ora Network Configuration File: /app/oracle/oracle/product/10.2.0/db_1/network/admin/listener.ora

# Generated by Oracle configuration tools.



SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (SID_NAME = PLSExtProc)

      (ORACLE_HOME = /app/oracle/oracle/product/10.2.0/db_1)

      (PROGRAM = extproc)

    )

  )



LISTENER =

  (DESCRIPTION_LIST =

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))

      (ADDRESS = (PROTOCOL = TCP)(HOST = suse10.site)(PORT = 1521))

    )

  )

2、修改它的 SID_LIST_LISTENER 中的内容，修改后的内容如下：

# listener.ora Network Configuration File: /app/oracle/oracle/product/10.2.0/db_1/network/admin/listener.ora

# Generated by Oracle configuration tools.



SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (SID_NAME = PLSExtProc)

      (ORACLE_HOME = /app/oracle/oracle/product/10.2.0/db_1)

      (PROGRAM = extproc)

    )

    (SID_DESC =

      (GLOBAL_DBNAME = ORCL)

      (ORACLE_HOME = /app/oracle/oracle/product/10.2.0/db_1)

      (SID_NAME = ORCL)

    )

  )



LISTENER =

  (DESCRIPTION_LIST =

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))

      (ADDRESS = (PROTOCOL = TCP)(HOST = suse10.site)(PORT = 1521))

    )

  )

上面的红粗体文字是增加的内容。



3、重启Oracle的监听器。

问题解决。
