CPU busy, as plotted on a graph, is not a linear function. And yet, many of us assume it is, and use that assumption for capacity planning. While linear regression may work for CPU busy functions from 20-80%, it doesn’t help you much at the lower or higher end of the utilization graph. And that’s where you actually want to know the impact of changes in transaction volume or batch workload.
ThruPut Manager includes Software Access Control (SAC), a feature that enables refined access control to licensed software. Without it, it’s easy to make the mistake of running a job on a system that isn’t licensed for a required software or to run it on the correct system, but in a way that is at variance with the contract. In both cases, it’s going to cost you more money.
Where once it was enough to ‘keep the sucker running,’ sysprogs now need to contribute to saving money for their corporations. This new paradigm presents some big challenges; it requires that you understand a lot more about how hardware and software companies charge you so you can determine the big ‘wins.’ Automating access control to expensive software can aid in your search for savings.
It’s inevitable. As a sysprog, you run a complex analysis job in production and suddenly realize that your batch job is running forever and sucking up CPU time. While higher priority jobs most likely wait, you don’t really want anything running out of control. A poorly designed SAS job can really cause problems. A new production batch job might do the same thing. But what can you do to prevent it? How can you really manage batch CPU time?
As experienced technicians, we know how to do our job well and can quickly pick up new technologies and processes. But when it comes time for a significant software purchase, something we do much less frequently, it can be a challenge to be sure that we are doing everything we can to get the right solution. As someone who has been on both sides of the software acquisition game, this blogger has learned a few things that might help you feel more confident about your decision. You’ll be able to level the playing field with these suggestions.
Back in the 20th century, it was fairly common to find mountains of manuals organized in piles. The thought was that it would be easier to look things up if you had the manuals close to hand. Then, as now, documentation is like a treasure chest with a wealth of invaluable information. But few people read them. As the Internet became the source for all knowledge, manuals moved there; but, they received no more attention online than their predecessors on paper.
