Informix Error -904

Reasons / Common Causes

-904 fires when the Informix networking software's authorization file is missing on the licensed SQL server — per the official guidance, this indicates the networking software installation wasn't completed correctly, on either the workstation or the network server side.

1. An incomplete Informix networking software installation on the server, per the official guidance — the authorization file step wasn't completed.
2. An incomplete installation on the workstation side, per the official guidance — the installation review needs to cover both ends.

Solutions / Resolution

1. Review the installation steps on the workstation, per the official guidance, to confirm they completed without error.
2. Review the installation steps on the network server, per the official guidance, to confirm the authorization file was correctly put in place there.

Examples

N/A

This is an installation-completeness issue requiring administrative review on both the workstation and server sides, rather than a code-level example.

Diagnostic Checks

1. Review both the workstation and network-server installation logs/steps for the Informix networking software, per the official guidance.
