RE: MRT's & SRT's

["DeLong, Eric" <EDeLong@xxxxxxxxxxxxxxx>]

I think I agree with David on this one....  On iSeries, SLS ensures that a program object is only loaded into main storage once.  Each job that invokes that program manages the memory used by that program object for that instance.  This seems more akin to MRT, at least from main storage POV.

I don't think so -- the instance specific data is usually on the 
requesters machine, e.g. hidden input fields on a web page, or cookies.  
Afaik, once a web page has been delivered to a browser, the system 
forgets about it.
