Even knowledgeable performance experts make the mistake of throwing more resources at work. If 10 buffers are good, 15 would be even better. If we have more batch work, throw initiators at it; it will get things moving faster. But it turns out that overinitiation is very similar to putting up more toll collectors on a bridge.
In the 21st century, we’ve given up our tool belts, relished the tape robots that replaced running around hanging tapes, and enjoyed the ease of keying in parameters, code fixes, and more on a PC dedicated to our needs. So, perhaps, it’s time to give up things like hand-managing batch performance.
Sometimes, we stick with things because they’ve become habit. We know there is probably a better way to do them; but, we don’t want to fight the battle to get new software and face a learning curve.
Many ThruPut Manager users may not realize all the benefits they are getting from the base automation product, even before implementing Automated Capacity Management (ACM). We know that ThruPut Manager’s automation engine – Service Level Manager – can really speed up your batch workload.
In most cases, it can reduce your batch window. But it can also save you CPU cycles; and, anything you can do to put off an upgrade or reduce your MSU numbers means you’ve saved your company money. And that should be measured and reported.
We’ve heard the mantra so often—‘Mainframes are dead’—and yet, despite the fact that most major corporations still rely on the mainframe, some people just don’t get it. The good news is that Compuware Corporation, the world’s leading mainframe-dedicated software company, leads a mainframe renaissance through product development and key acquisitions, like ThruPut Manager.
A guest post by Denise P. Kalm – For 2017, I have a dream that more women will see the value of an IT career and that companies will leap to hire them. While there may be discrimination in some places, companies can’t hire more women if fewer are choosing this path. Better jobs with a diverse set of colleagues will attract more people to a field that is only growing bigger and more critical to business.
Companies are more cost-focused than ever before. While some industries have always had narrow margins, every company is looking for cost-savings wherever possible. Soft-capping can be scary, but you still need to save money. So what do you do? The solution is LPAR sets.
