应用程序仅升级到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"'无法在dll'oraops12.dll中找到名为'opsconisdrcpeNabled'的入口点'
也将ORAOPS12.DLL添加到输出文件夹中。''
这是跟踪堆栈

有什么建议如何解决这个问题？
我认为问题在这里：
加载'c： windows microsoft.net assembly gac_64 oracle.dataaccess v4.0_ 4.122.1.0 __ 89b483f429c4733c47342
加载'c： windows microsoft.net assembly gac_64 oracle.dataaccess v4.0_ 4.121.2.0 __ 89B483F429C477342
看来您的升级到12.2。OraOps12.dll的版本似乎与Oracle.DataAccess.dll的版本不匹配
用gacutil.exe仔细检查您的GAC中安装的内容。您可以使用这些命令正确配置GAC（选择与您相关的行）

而不是OraProvCfg.exe，也可以使用gacutil.exe。
