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.
IBM’s Country Multiplex Pricing (CMP) became available last October. This is arguably the most significant software pricing announcement from IBM in ten years. Virtually every mainframe shop with more than one CPC/CEC should be interested in this announcement.
But don’t think you can just move to CMP and immediately see lower software bills – if you don’t do it right, your annual costs could actually be higher. Whether you’re in finance, capacity planning or performance, you don’t need to be a ThruPut Manager user to get significant value from this webinar.
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.
For those exploiting the benefits of sub-capacity pricing to reduce IBM software costs, the Rolling 4-Hour Average (R4HA) is a critical measure to watch—but are you watching it effectively? If you’re like many systems programmers and capacity managers, you’ve probably created a specific job to keep your company’s R4HA in check.
This job likely focuses on key online workloads—those that impact the costs of CICS, IMS, DB2 and other licenses—and monitor changes to transaction mixes, new workloads and code, which can all cause your average to creep up, leading to increased software charges. Despite this effort, however, you may continue to see your R4HA rise, because you’re missing one sneaky cost contributor: batch.
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.
