Installed many times Oracle, Shun smoothly, today in the new Installation oracle12c client process unexpectedly magically reported a mistake:
It is clear that the reason for the installation failure has been clearly given: the temporary location cannot be accessed. In fact, before you install the database, the database checks to see if the prerequisites for meeting the database installation database are met. In fact, Oracle performs prerequisite checks that rely on the C $ share, and many system administrators shut down this by default for security.
So how to solve this problem. Here are two ways to:
1. The easiest way to do this is to enter a line sharing command in CMD.
Advanced settings for details require the following stupid method.
2. The stupidest way:
Cough up and find management tools.
Turn on Computer Management:
Double-click to locate the shared folder.
Right-side "sharing"
Wizard to enter folder sharing settings
Input Letter: C:\
Ignore options.
Enter share name: C $
Rotate the permissions on the folder share as needed.
Click Finish.
