原因/解决方法：
1、分析Oracle的启动过程，没有发现问题，其启动信息如下：
oracle@suse10:~> lsnrctl start LSNRCTL for Linux: Version 10.2.0.1.0 - Production on 17-APR-2010 17:05:04 Copyright (c) 1991, 2005, Oracle. All rights reserved.

2、在sqlplus中查询数据，同样正常：
oracle@suse10:/app/oracle/oracle/product/10.2.0/db_1/network/admin> sqlplus servicemn/servicemn

看来，数据库是没有问题的，那问题应该出在了监听器上。
3、打开Oracle的 listener.ora 文件：
# 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))
)
)
上面的粗体文字是增加的内容。 4、重启Oracle的监听器。
