Security patching is considered as consultancy; and can be requested by the customer. Xynomix will provide a Statement Of Work for customer acceptance and sign-off.

What happens if I’m running an unsupported version of an Oracle product?

Xynomix recommends raising a Service Request (SR) with Oracle for any unlisted, or unsupported products you suspect as being affected.
