Informix Error -9465: Must specify dbname in the URL.

Reasons / Common Causes

-9465 fires when a JDBC URL is missing the database name — per the official guidance.

1. A JDBC URL with no database name segment, per the official guidance — the direct, only cause.

Solutions / Resolution

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

Examples

A JDBC URL missing the database name

"jdbc:informix-sqli://host:port/:INFORMIXSERVER=srv;user=myuser;password=secret"
-- -9465: no database name before the ':'

Corrected

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

Diagnostic Checks

1. Check the JDBC URL for the database-name segment, and add it if missing.

The JDBC URL was missing the database name — add it before the server-parameters segment.
