Visit the official address Oracle Instant Client Downloads and select the appropriate version. This time, taking window as an example, select the 64-bit version.
Enter the download page and select the latest version V21.10.0.0.0. Users can also choose the version that suits them according to their actual needs. Click the + on the right to display the download list.
Download the basic package of Instant Client.
2. Set up Navicat’s oci environment
Unzip the Instance Client Base downloaded in the previous step to any folder. Then select Navicat->Tools->Options to enter the option configuration page.
Select environment options on the options configuration page. Then configure the OCI environment and select the oci.dll file in the decompressed folder of the Instance Client Base downloaded in the first step.
