What remote libnames are assigned?

I was attempting to upload some SAS formats from my local PC to the SAS server and while there was no error message in the log, the formats did not get updated. I had assumed the APFMTLIB was already assigned but it was not and the way I determined that was via the following code.

signon ;
  rsubmit wait = yes ;

    proc sql ;
      create table onserver as
        select   libname
               , path
          from   dictionary.libnames ;
    quit ;

    proc download
      data = onserver
      out  = localdsn ;
    run ;

  endrsubmit ;
signoff ;
