Informix Error -9468: Cannot make UDR connection in non-UDR thread.

Reasons / Common Causes

-9468 fires when a UDR (server-side) connection is attempted from a thread that isn't the one executing the Java UDR — per the official guidance.

1. The connection created on a child thread forked by the UDR, rather than the UDR's own executing thread, per the official guidance — the direct, only cause; a UDR connection can be made only from the thread executing the Java UDR.

Solutions / Resolution

1. Make sure the connection isn't created on a child thread forked by the UDR, per the official guidance — create it directly on the UDR's executing thread.

Examples

N/A

No specific triggering statement is documented beyond creating the connection on a forked child thread.

Diagnostic Checks

1. Check the Java UDR's code for where the JDBC connection is opened, and move it onto the UDR's own executing thread if it's on a child thread.
