Download the 18, 12, or 11.2 “Basic” or “Basic Light” zip file from https://www.oracle.com/technetwork/topics/intel-macsoft-096467.html. Choose either a 64-bit or 32-bit package, matching your application architecture. Most applications use 64-bit. | |
Unzip the package into a single directory that is accessible to your application. For example: | |
mkdir -p /opt/oracle | |
unzip instantclient-basic-macos.x64-12.2.0.1.0.zip |
