我创建了以下个人资料。

create profile EXPTESTPROF limit failed_login_attempts unlimited password_life_time 1/24/60/60 password_reuse_time unlimited password_reuse_max unlimited password_verify_function null password_lock_time 1  password_grace_time 31;

alter user exptest profile EXPTESTPROF;

当我尝试从命令提示符登录时，它成功登录并显示以下错误消息。

错误：
ORA-28002: 密码将在 30 天内过期

直到我没事为止。

但是我为 OCI 登录和一些操作编写了一个小程序。

当我使用上述用户调用 OCILogon 时，它返回 1 的地址OCI_SUCCESS_WITH_INFO。

之后，我尝试OCI_HTYPE_SVCCTX使用OCIAttrGet它来获取返回-2的地址OCI_INVALID_HANDLE。

为什么句柄会损坏？有什么办法可以克服这个问题并一直工作到宽限期结束？

请在下面找到示例 OCI 客户端。

问题出在 OCI Api 中，并且已在 oracle11g R2 中修复 –
