When installing Informix, consider installing to a version specific location, instead of accepting the default.
This will allow you to install multiple versions, and switch between them as needed.
For example, to install and test a new version, while the existing version continues to run.
Use the infx idsinstall command to automatically install Informix software to a version specific location.
After you install infx, you run the discovery service to locate existing Informix instances. This automatically configures infx to access and manage them.
The infx disco command locates instances in the output of onstat -g dis, reads their ONCONFIG files, and creates the required files and directories.
This all happens automatically in the background, the purpose of this post is to go through each of those steps in more detail.
