'在DLL'OraOps12.dll'中找不到名为'OpsConIsDRCPEnabled'的入口点-Oracle 12c

Question

该应用程序只需升级到Oracle 12.2.0.1。 下载Oracle 12.2.0.1客户端，还尝试了ODAC122010Xcopy_x64.zip，但出错了相同的消息“'在DLL'OraOps12.dll中找不到名为'OpsConIsDRCPEnabled'的入口点”

还将OraOps12.dll也添加到输出文件夹中。''

这是跟踪堆栈

ApplicationXYZ.dbaccess.dll中发生类型'System.EntryPointNotFoundException'的异常，但未在用户代码中处理。无法在DLL'OraOps12.dll'中找到名为“ OpsConIsDRCPEnabled”的入口点。

有什么建议如何解决这个问题？

我认为问题出在这里：

已加载'C：\\ WINDOWS \\ Microsoft.Net \\ assembly \\ GAC_64 \\ Oracle.DataAccess \\ v4.0_ 4.122.1.0 __89b483f429c47342 \\ Oracle.DataAccess.dll'

加载'C：\\ WINDOWS \\ Microsoft.Net \\ assembly \\ GAC_64 \\ Oracle.DataAccess \\ v4.0_ 4.121.2.0 __89b483f429c47342 \\ Oracle.DataAccess.dll'

看来您未正确升级到12.2。 OraOps12.dll版本似乎与Oracle.DataAccess.dll版本不匹配

使用gacutil.exe仔细检查GAC中安装了什么。 您可以使用以下命令正确配置GAC（选择与您相关的行）

如果您愿意，也可以使用gacutil.exe代替OraProvCfg.exe 。
