Creating group informix and user informix

Create the group informix and user informix if they do not already exist.

1. Log in as user root.
2. Create the group informix using the groupadd utility followed by the name of the group, in this format:

   groupadd n

   where n is an unused group ID greater than 100.
3. Create the user informix using the utility useradd followed by the group (informix) and username (informix) in this format:

   useradd -u n -g informix informix

4. Create a password for the user informix.

   To do this, use the passwd utility and the following command:

   passwd informix

5. If you use a network, propagate the new user name to all the systems on the network that must recognize the user informix. For example, on some systems, you (or the network administrator) must run the ypmake utility.
