今天在本机上连接rman时抛出12514的错误：

RMAN-00571:
RMAN-00569: ERROR MESSAGE STACK FOLLOWS
RMAN-00571:
RMAN-00554:内部恢复管理器程序包初始化失败
RMAN-04005:目标数据库中存在错误:
ORA-12514: TNS:监听程序当前无法识别连接描述符中请求的服务
这个错误很常见，造成这个错误的原因也比较多，根据在线文档上的错误描述为：
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
Cause:The listener received a request to establish a connection to a database or other service. The connect descriptor received by the listener specified a service name for a service (usually a database service) that either has not yet dynamically registered with the listener or has not been statically configured for the listener. This may be a temporary condition such as after the listener has started, but before the database instance has registered with the listener.
Action:
- Wait a moment and try to connect a second time.
- Check which services are currently known by the listener by executing: lsnrctl services
- Check that the SERVICE_NAME parameter in the connect descriptor of the net service name used specifies a service known by the listener.
- If an easy connect naming connect identifier was used, check that the service name specified is a service known by the listener.
- Check for an event in the listener.log file.
笔者这边遇到的情况为，每次关闭数据库重新启动后都会抛这样的错误。
SQL> shutdown immediate;
数据库已经关闭。
已经卸载数据库。
ORACLE例程已经关闭。

ERROR:
ORA-12514: TNS:监听程序当前无法识别连接描述符中请求的服务
察看监听文件的配置为：
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
) ----注意这里缺少了相应得数据库服务
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = COLIN)(PORT = 1521))
)
)
下面呢就利用net manager为监听添加相应得数据库服务了
注：上面是一个添加数据库服务的图片
服务添加完成后，保存下，再看监听的配置：
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = colin)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(SID_NAME = colin)
)-------相应的数据库服务添加上了
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = COLIN)(PORT = 1521))
)
)
好了下步就是要重新装入下监听器
C:\Documents and Settings\Administrator>lsnrctl reload
LSNRCTL for 32-bit Windows: Version 10.2.0.1.0 - Production on 17-7月-2007 12:0
2:25
Copyright (c) 1991, 2005, Oracle.All rights reserved.
正在连接到(DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1)))
命令执行成功
我们再来显示下监听的状态：
C:\Documents and Settings\Administrator>lsnrctl status
