错误ORA-12545: Connect failed because target host or object does not exist

[StoneStark]

在虚拟机中安装了linux作为客户端，然后连接局域网内的ORACLE服务器(安装在win7下)，配置完linux客户端后，使用sqlplus test/000000连接时报错
ORA-12545: Connect failed because target host or object does not exist。。。。。。。。。
WIN7服务器端主机名admin-PC，ORACLE服务名APP，用户名test 密码000000

linux客户端下tnsnames.ora内容：ORACLR_CONNECTION_DATA =

sqlnet.ora
里面

SQLNET.AUTHENTICATION_SERVICES= (NTS)

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
试一试 看看

咋样了？
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = admin-PC)(PORT = 1521)) 把这里admin-PC改成IP
)
)

这样可以吗

不行,sqlnet.ora我也加上了;HOST客户端我改为了 admin-PC也不行.......
然后又尝试把服务器的HOST改为IP地址,也不行...............
上网不太方便,回复有点晚,不好意思啊.........
