those set options are connection specific; they are not server wide.
just because you set it someplace, does not mean it's going to affect jobs or anything else on the server.
each job would need to be edited to have new set options.
if you are connecting with , say .NET, you need to set the options there.
SSMS has a place where you can change most of those settings via the GUI , and every ODBC driver has the ability to set them as well.
Note that even if you could set these items server wide, they would be over-riden by the connections settings themselves.
