The following is a complete workaround: 1: Download the file in the above address: Instantclient-basic-nt-11.2.0.3.0.zip 2: Unzip this installation package and merge the extracted files into: D: Appuserproductinstantclient_11_2 3: Open navicat, select tools → options → other →oci, then set OCI Library as: D:app\user\product\instant\client_ 11_2\oci.dll, set the SQL *plus to: D:app\user\product\11.2.0\dbhome_1\bin\sqlplus.exe.  Are you sure. 4: Test success.
