Informix Error -41002

-41002 The INFORMIX.INI file does not have a username or has a format error.

Check the INFORMIX.INI file. If you did not define a user name variable in the InetLogin structure, the [INET_CONNECTION] section must have a user name. You must define the user name in the [INET_CONNECTION] section with the following format:

user=username

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-41002 fires when INFORMIX.INI's [INET_CONNECTION] section is missing a user name, or the InetLogin structure didn't define one in code — per the official guidance.

  1. No user name variable defined in the InetLogin structure, and none in [INET_CONNECTION] either, per the official guidance — the direct, only cause.
Solutions / Resolution
  1. Define the user name in [INET_CONNECTION] using the format user=username, per the official guidance.
Examples
The required user-name format
[INET_CONNECTION]
user=myuser
Diagnostic Checks
  1. Check [INET_CONNECTION] for a user=username line, and add or correct it if missing or malformed.
