Hi, Many years ago, we created an application that would attach a R/W DCSS to use for extra memory. As the demands for more memory increased, subsequent DCSS space would be attached. We used to attach existing DCSS space (such as VTAM) for testing (no, this would no trash the real VTAM segment, we'd just ATTACH the DCSS in R/W mode, thus extending our virtual machine storage dynamically). I was wondering if Linux on 390 could be taught how to do this. Can Linux on 390 handle "holes" in it's address space?
Cheers, Arty
