Haha! I cannot remember the error description, which is a problem I encountered before. It is estimated that it will not take much time for me to solve such a problem in the future, but I still want to write it out. Maybe it will help some people someday.


Approximate Problem description:


The Oracle database is used in the development system on Windows x86. After the system has been developed and deployed on Windows x64, the problem arises and the connection fails. What should I say: "If the 32-bit Oracle client component is installed, it runs in 64-Bit mode, this problem will occur ".



Cause analysis:


There are special symbols in the Access Directory, which is a problem with program files (x86.




Install Microsoft Visual Studio in another directory. Alternatively, you can install Oracle patches.
