The user should perform a reading of the release note under the $informixdir/release directory during the initialization of the system. This file contains a number of important information related to the operating system, kernel parameters, and system updates.

The machines have preset core configuration parameters at the factory, but they need to be adjusted further if the user wants them. Check release notes for core parameter configurations.

When you prepare disk space for your system, you must first set the following permissions correctly:

chmod 660 device_name
chgrp informix device_name
chown informix device_name

We recommend that users have the best ability to create linked files for the original device for two reasons:

2. Easy recovery.
