Trying to connect to ADWC server , and to determine whether it is ADWC or not we execute 'SELECT SYS_CONTEXT ('USERENV', 'CLOUD_SERVICE') FROM DUAL;'. But we get invalid parameter error. This query was provided by Oracle team. Is 'CLOUD_SERVICE' a valid parameter of 'userenv'. If yes, why is it throwing this error ? Also there's no documentation of this in oracle. I f no, how should we determine the adwc server info.
Please provide insight, as I am blocked.
Can someone reply on this please ?
