Re: Save CPU in z/OSMF and reduce its startup time

I run on zD&T machine on Linux. z/OS starts in about 60 seconds. I'm trying to find out why z/OSMF does not work with Elliptic Curve certificates. With shared cache, and all I/O in ZFS cache - it takes over 2 minutes to start ( and this is the thinnest possible, and no plug ins!).This probl

Re: Use of TAR to test access register validity

A problem state program can validly create and use a SCOPE=SINGLE dataspace , so the ability to test an AR via TAR is valid in that environment. Perhaps having an ESTAE(X) and catching any 0C4 abends would be better in some circumstances, but there is nothing inherently wrong with using TAR. Ro
