Installing
Extract the contents of all the above into a single directory called D:OracleOra11
That directory doesn’t exist and you’ll have to create it first.
Now with all the files copied in there, create the following windows environment variables:
Drivers
1) OCI_LIB64 = C:OracleOra11
3) TNS_ADMIN = C:OracleOra11
Also, add “C:OracleOra11” to your PATH variable.
At this point you MUST reboot. No other way around it. Simply restarting the explorer task won’t do.
After the reboot, create the following directory: C:OracleOra11NetworkAdmin
Place your tnsnames.ora file inside this new directory.
Open a cmd prompt as administrator.
On the command prompt type the following command:
Drivers
odbc_install.exe
