Use this command to set up your shell environment for a specific instance. For example, set up to manage instance named demo01.
infxenv demo01 

To enable this, add the following line to your .bashrc or .profile.

alias infxenv='. /infx/scripts/infxenv'

Otherwise, you can set your environment directly

. /infx/scripts/infxenv infx01

  • see config.ini for more information on setting configuration parameters
  • by default infx looks in /infx, /usr/infx, /usr/local/infx or /home/informix/infx for the software
  • set environment variable INFX if you want to use a different location
  • set environment variable INFX if you want to have multiple infx versions installed
