本文介绍如何在Oracle的listener.ora文件中正确配置SID_LIST以添加新的数据库实例，并提供了一个具体的修改示例，包括如何重启监听器来使更改生效。

解决方法：

打开Oracle的 listener.ora 文件：

（oracle/oracle/product/10.2.0/db_1/network/admin/listener.ora）

修改前：

# 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))
)
)

修改后：

# 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))
    )
  )

上面的红色文字是增加的内容。 (ORCL -- 是你的SID 数据库名)

重启Oracle的监听器。

问题解决。
