我有一个oracle服务器12c，并希望从带有sqlplus的Windows机器连接。
服务器版本是12.2.0.1 SQLPlus是11.2.0.1
当我连接到服务器时，如“sqlplus user / pass @ ORCL”我收到了错误
ORA-01017: invalid username/password; logon denied
凭据是正确的。使用SQLPlus 12.2，它可以正常工作。
通过检查支持矩阵，它也适用于11.2.0
所以这是来自windowsclient的tnsnames.ora
ORCL =
(DESCRIPTION=
(ADDRESS=
(PROTOCOL=TCP)
(HOST=10.162.6.52)
(PORT=1521)
)
(CONNECT_DATA=
(SERVER = DEDICATED)
(SID=orcltok)
)
)
用户的PASSWORD_VERSION是11g和12c。 我从dba_users检查过。
我希望有人给我一个提示。
祝福 奥利弗

我对你的任务很感兴趣，我在oracle XE 11g和即时客户端11上做了一个实验。

如果用户名包含不同寄存器中的字母，则sqlplus 11和12始终将用户名转换为大写。如果你像这样运行它
sqlpus "Scott"/TigeR@aws这相当于sqlpus "SCOTT"/TigeR@aws。
如果您首先运行sqlplus /nolog命令
然后是connect "Scott"/TigeR@aws。这一切都联系在一起。
