【问题描述】:
在 Oracle11g 数据库上,这是可行的:
SQL> connect USER/pass
Connected.
但是,这不是:
SQL> connect USER/pass@db
ERROR:
ORA-01017: invalid username/password; logon denied
我已经执行了:
SQL> grant connect to USER;
Grant succeeded.
我错过了什么?
tnsnames.ora:
DB =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = a.dom.b.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = db)
)
)

这会产生标识符错误:

ERROR:

我已经验证了 tnsnames.ora 条目,并且我的 service 拼写正确。

【问题讨论】:
-
您的
db是有效的 TNS 名称吗? -
是的,我添加了清除的 tnsnames 条目。
-
USER 在两个数据库上的密码是否相同?你可以简单地输入一个无效的密码......
-
每次输入的密码都是一样的。
-
@mdobrinin - sqlplus 是否接受来自命令行的连接参数?示例:
sqlplus user/pwd@db和sqlplus user/pwd@//host:1521/servicename
