If you have a Singleton you can use it to store instances.

newCustomer := Customer new.
Customer currents add: newCustomer.

Now the newCustomer is the server.
But it depends on "the structure" that you have in your GemStone/S server.

Your singleton can be part of your:
System myUserProfile symbolList


But every object that is create inside de GemStone/S scope "it born"
persistent (stored).
What you do is put the new object in some part of the server root.
