The mainframe capacity usage needs to be seen in the context of the measures that drive the TCO of the mainframe. While there are a number of tools available to analyze application- or transaction-wise capacity usage, these tools are currently unable to analyze the activity within individual business applications. Like, for instance: Is the mainframe processing new or existing business or is the mainframe engaged in re-work on an existing application etc?
This paper will argue that enterprises need a solution that can identify the cost of mainframe computing power. It focuses on a solution to identify the cost of the mainframe used by various business products based on the use of the mainframe capacity. This would facilitate understanding the mainframe TCO, and provide pointers to pro-actively manage mainframe capacity and cost; and identify opportunities for future investment in business applications.
In this white paper, we focus on a solution to identify the cost of the mainframe used by various business activities. This would facilitate an understanding of the mainframe’s TCO and provide pointers to proactively manage mainframe capacity and cost and identify opportunities for a future investment in business applications.
Based on our feasibility study, we conclude that the business product-wise chargeback is doable in the mainframe environment by appropriately identifying the business products, and determining the resource utilization costs by the associated transactions/jobs.
