Informix Error -9464: Must specify user=name in the URL.

Reasons / Common Causes

-9464 fires when a JDBC URL is missing the username — per the official guidance.

1. A JDBC URL with no user=name parameter, per the official guidance — the direct, only cause.

Solutions / Resolution

1. Make sure the JDBC URL contains the username, per the official guidance.

Examples

A JDBC URL missing the username

"jdbc:informix-sqli://host:port/db:INFORMIXSERVER=srv;password=secret"
-- -9464: no user=name

Corrected

"jdbc:informix-sqli://host:port/db:INFORMIXSERVER=srv;user=myuser;password=secret"

Diagnostic Checks

1. Check the JDBC URL for a user=name parameter, and add it if missing.
