The Service Group Definition is found in the Service Group Definition File in the Country directory or library which was loaded at install time. It is best practice to work with a copy of the Country Definition Files rather than with the originals.

Taking the USA as an example, at install time the directory or library called USA was loaded. On the Windows computer this should have been copied to a directory called

myusa

. On MVS this should have been copied to a library called

USER.USA

. Within

myusa

or

USER.USA

, there is a file called

n3sgus(.def)

. This is the Fast-start Service Group Definition file for the USA.

For a different country, simply change the country code to one of the codes found in Country Codes section.
