连接oracle时localhost可以ip地址不可以
在本机安装了oracle,使用sqlplus和plsqldev连接的时候,tnsname.ora中host写的是localhost,此时连接oracle都没有任何问题,但是外机连接本机,和tnsname.ora中host写成ip地址(192.168.1.110)是,报错ora-12547,没有监听等

解决问题,oracle自带管理工具,程序-》oracle-oracle...-》配置和移植工具-》Net Manager中找到本地,LISTENER,添加一个监听服务地址,然后重启oracle监听服务,然后就可以使用localhost和ip地址对oracle进行访问了
LISTENER.ORA文件
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.110)(PORT = 1521))
)
)
TNSNAME.ORA文件
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
ORCLIP =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.110)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
