Following a hockey puck can be challenging. It moves really fast and it’s not always obvious what the next player is going to do. Wayne Gretzky famously said: “Skate to where the puck is going; not where it’s been”. The same analogy can be applied in most sports: football quarterbacks throw to where the receiver is going to be; not where they are. Your monthly 4-Hour Rolling Average (and resulting MLC) is also a moving target.
By now, many shops are using soft caps and/or taking advantage of special pricing offerings from IBM such as Mobile and zNALC. These are excellent ideas — but, as all performance and capacity professionals know, reducing one 4HRA bottleneck only creates another.
You know you need to reduce software costs wherever possible. Fine tuning of your batch can do this for you. IBM may recommend using a single LPAR group (Group Capacity soft cap limit) for all LPARS on a CPC; but, this implementation might not work for you on every CPC. You might have LPARs with products or applications that differ a great deal in CPU hourly usage rates from other LPARs. What you really want is to have all the control possible to ensure you strike the right balance between cost savings and performance. A brand new feature of ThruPut Manager can help.
A guest post by Denise P. Kalm – When BMC Software releases the results of its latest survey showing that 90% of the participants are confident in a long-term future for mainframes, you have to listen. Or more importantly, the management teams who keep trying to move off of it needs to read the report. While security and availability are frequently cited as important factors – who has hacked a mainframe lately – too often forgotten is the unequalled ability to manage costs on this platform.
Very often, with distributed systems, the cost is the cost; you pay for seat licenses or for the total capacity of the box or some other immutable metric. And let’s not forget the lower availability statistics, nor the fact that Wintel boxes are the biggest targets for hackers. But back to cost, because every systems programmer has had to become an active participant in managing and reducing costs. Which platform is the most flexible in terms of cost?
Long ago, it was commonplace for the ‘deadwood’ of every department to be pruned. Today, with massive layoffs reported nearly every month in the IT industry, it’s clear that no one—not even the high performer—is immune to this threat.
To protect yourself, you must to take action to bullet-proof your career by finding new ways to demonstrate your value on a continuing basis. The best way to do this is to align your priorities to those that management rates highly. After all, when you deliver on your manager’s hot issues, you’ll stand out as a key player.
A guest post by Denise P. Kalm – Layoffs, outsourcing and wage-stagnation, oh my! The 21st century workplace hasn’t been all that kind to IT workers, leaving us fearful about our jobs, insecure about retirement and desperate to simply survive. While the 20th century was largely marked by rewarding technical prowess, this new century is different. IT investments are no longer the absolute guarantee of profitability and competitive edge.
While most business units have long been focused on ensuring net profits, IT, as a cost center, was not. With the economic downturn, cost centers were no longer okay – everyone has to have an eye on profit. This means us. No matter what your role in IT, but especially if you are in capacity planning or performance, you need to expand your role to look at the balance sheet as it applies to your department.
In a tight job market, one of the most important keys to getting your résumé to the top of the stack, and landing an interview, is to have measurable achievements that mean something to the business.

Thanks to ThruPut Manager, you can achieve the seemingly-impossible while simultaneously making your job easier. The truth is that with the help of the smart automation of ThruPut Manager, you can begin to add significant line items to your résumé without changing the way you work now.
WLM Resource Groups have been around since the introduction of Goal Mode. Their use is often discouraged as their static nature can work against the dynamic nature of Goal Mode.
What if Resource Groups could be automated? What if you could dynamically move selected work in and out of Resource Groups with varying maximums? What if this automation was sensitive to the R4HA as well as application business priorities?
Rather than just limiting consumption of out-of-control workloads, intelligent automation can harness the power of Resource Groups to reduce software costs without capping or impacting critical workloads. Learn how Resource Groups really work under the covers, and how ground breaking automation with ThruPut Manager delivers new value to an old function.
