The optional facility is not supported on this CAPI Connection type. The CAPI facility “NotifyCurrentEndOfLog” is used to ensure that all records are read (without the job ending through a time out) up to the current end of log position, together with logging of messages PWX-09966 and PWX-09967. The “NotifyCurrentEndOfLog” is not supported on the old CAPI_CONNECTION type of EDPQ under z/OS PAC jobs.
