Informix Error -9636: Opaque type exceeded its maximum length.

Cause and resolution

Opaque type exceeded its maximum length.

Opaque types are defined with a maximum length that cannot be exceeded. Verify that user-defined routines that return the type do not attempt to exceed the size limit.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-9636 fires when a value of an opaque type exceeds the type's defined maximum length — per the official guidance.

  1. A user-defined routine returning a value larger than the opaque type's maximum length, per the official guidance — the direct, only cause.
Solutions / Resolution
  1. Verify that user-defined routines returning the type don't exceed the size limit, per the official guidance.
Examples
N/A

No specific triggering statement is documented; the specific opaque type and its defined maximum length vary.

Diagnostic Checks
  1. Check the opaque type's maxlength definition and the UDR's output size, and correct whichever is producing oversized output.
