I have an Oracle client installed on my workstation. tnsping reports:

C:\temp> tnsping

TNS Ping Utility for 32-bit Windows: Version 12.2.0.1.0 - Production on 06-JUL-2018 09:22:33

However, it does not appear in Control Panel Programs. The only Oracle thing there (other than Java) is

Oracle data Provider for .NET Help

I just want to understand this (apparent) disconnect. Bingoogle found nothing (or I didn't ask the question the right way).

If it's an Instant Client, there is no installer, there is no official windows application installation.

Instead, it's a Zip archive that you extract to a local folder and simply add it's 'bin' folder to your machine's PATH.

Or as the docs say..

Installation

See the Instant Client Home Page for more information about Instant Client packages.

  1. Download the appropriate Instant Client packages for your platform. All installations require the Basic or Basic Light package.

  2. Unzip the packages into a single directory such as C:\oracle\instantclient_12_2

  3. Add this directory to the PATH environment variable. If you have multiple versions of Oracle libraries installed, make sure the new directory occurs first in the path

However, if you installed the client using "setup.exe", then - if it (or any other program you install) creates a registry key whose name is longer than 60 characters, it won't be displayed in "Programs" in Control Panel.
