An XA roll back request to system System name failed because RRS is downlevel (RRS call RRS function call failed)
The Gateway daemon is unable to roll back unit of work on system System name because the RRS APARs which implement function call RRS function call are not installed on system System name , or the Gateway is running on an unsupported level of z/OS.
This message is logged and the Gateway daemon continues. Units of recovery might be in an incomplete state and might need to be resolved manually.
Check that all units of recovery associated with the Gateway in RRS are in a completed state. Check the CICS® Transaction Gateway Information Center for the RRS APARS required by the CICS TG at your level of z/OS. Install the required service and restart the Gateway.
