我无法从SQL plus连接到Oracle数据库。这是我收到的错误消息：
Status: Failure -Test failed: Listener refused the connection with the following error: ORA-12505. TNS: listener dos not currently know of SID given in connect descriptor
这是 listener.ora：
的配置# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.104)(PORT = 1521))
)
)
ADR_BASE_LISTENER = /u01/app/oracle
的 sqlnet.ora中： 的
# sqlnet.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/sqlnet.ora
# Generated by Oracle configuration tools.
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
ADR_BASE = /u01/app/oracle
的的tnsnames.ora： 的
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora

ORACLE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.104)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = oracle)
)
)
我如何解决问题？
的 P.S 的 这是命令lsnrctl status
的输出[oracle@localhost bin]$ ./lsnrctl status
