More reaction on IBM z/OS 1.12 mainframe operating system preview

The new predictive failure and analysis features of z/OS 1.12, due out in September, continue to intrigue IBM mainframe end users.

Last week IBM previewed the new version of z/OS 1.12. Just last night I heard from Robert Rosen on his take of the new z/OS version. Rosen is a past president of IBM computer user group Share, currently serves as the CIO of the National Institute of Arthritis and Musculoskeletal and Skin Diseases of the National Institutes of Health, U.S. Department of Health and Human Services, and is also a member of’s data center advisory board. Here is what he had to say:

The parts that appeal to me relate to the predictive failure and analysis pieces.  Anything that improves reliability or enables me to avoid outages is always important.

Also like the cryptography improvement.

Like to see some more integration with open environments.  They’ve made great improvements but the more the merrier.

Predictive Failure Analysis was first introduced in z/OS 1.11. In z/OS 1.12 due out in the fall, PFA will be able to monitor the rate of systems management facilities (SMF) record generation. If it’s abnormally high, it will send a warning message that could potentially prevent an outage. It will also be able to take into account normal activity spikes to prevent false alarms. Run Time Diagnostics, another feature, will help mainframers determine problems that are affecting the performance while the machine is live.

In terms of cryptography, z/OS 1.12 is planned to support elliptic curve cryptography, a form of cryptography that has been endorsed by the National Security Agency, which if you don’t know already, likes to keep secrets.

Thanks for Rosen for chiming in.
