Even without Automated Capacity Management (ACM), ThruPut Manager’s automation engine – Service Level Manager – can really speed up your batch workload and, in most cases, 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.
A guest post by Denise P. Kalm – Not that we get a lot of ‘gifts’ at work, except the ‘opportunities’ to do a new, hard project with an impossible deadline. But a real gift would be software that would make 2017 a lot easier. Have you considered that sometimes, there is a little money left in the budget year? Use it or lose it! But what would you buy? How about some automation to free up your time in the coming year?
A properly tuned and conducted orchestra can produce amazing sounds. One out-of-tune instrument can ruin the whole performance. Your mainframe is no different. A well architected and tuned system can support thousands of users and applications with sub-second response. But it only takes one small parameter or threshold to be exceeded and the whole system feels like it’s grinding to a halt.
There is no shortage of available metrics to provide detailed insight into system performance. The problem is sorting through them all and recognizing what’s important. Utilization, for example, comes in many forms. Hiperdispatch can make or break performance, and processor cache… well, a faster CPU won’t help you with a cache miss. This session will discuss these and other key performance areas to watch, what to look for, what to ignore, and what… well, as they say – it depends.
For many in the USA, the 4th of July is filled with barbecues, sports, and family with no thought about the meaning of Independence Day and the sacrifices made to ensure American freedoms. I think that’s a mistake; we take our freedoms for granted, no matter where we live. But we also can fail to exercise them as much as we can.
This happens a lot at work. When you find yourself doing too many low reward tasks, you have to ask yourself, “Why am I working this way?” But too often, we don’t ask and continue to toil away wondering why our efforts don’t lead to raises, bonuses and promotions.
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?
The cure for the summer blues is to have batch managed automatically, so that in most cases, problems will be resolved without your intervention. You will have the luxury of coming in and reading the notes on what was done for you, instead of driving into work (or better, but not great), holing up in your house or hotel and managing the problem remotely. Summer is the perfect time to consider automation. Isn’t there somewhere you’d rather be right now? ThruPut Manager has to be in your summer game plan.
Every year, when the switch to daylight savings time takes away an hour of sleep but gives you back light in the evening, many of us think about doing some spring cleaning. Have you ever considered how you could do some spring cleaning around the office? While cleaning your workspace is a great idea and one too rarely considered, you’re going to get more points from looking at some ‘systems spring cleaning.’ What would that look like?
