Mainframe Optimization Services
Stop overpaying for unused capacity. We’ve helped clients save over $1B USD by aligning hardware spend with actual business demand.
Reduce licensing costs
Target the specific workloads and peak windows driving your MLC and TFP expenses.
Stop batch bottlenecks
Reduce resource contention so critical CICS transactions and batch jobs run more efficiently.
Defer hardware upgrades
Maximize your existing MIPS capacity to support business growth without immediate CapEx increases.
What is mainframe optimization?
Mainframe optimization is a technical approach to improving the efficiency of z/OS environments and reducing the Millions of Service Units (MSU) consumed.
By tuning subsystems like Db2 and CICS and flattening the Rolling 4-Hour Average (R4HA), your organization can significantly lower IBM Monthly License Charge (MLC) costs and defer expensive hardware upgrades.
Our proven optimization approach
We’ve helped clients save over $1B USD, leveraging over 30 years of global SMF and RMF data analysis to align technical performance with IBM’s most complex pricing models.
Subsystem & Code Tuning
Surgical optimization of DB2, CICS, and IMS. We analyze SMF/RMF data to fix inefficient code paths that automated tools miss.
WLM & R4HA Management
Calibrate z/OS and related subsystem configurations to flatten the 4-hour rolling average.
IBM Pricing Model Alignment
Whether on Consumption or Tailored Fit Pricing (TFP), we align technical performance with your specific IBM contract.
Solving your mainframe overhead challenges
Expert insights into overcoming performance bottlenecks, managing R4HA peaks, and maximizing ROI on your existing MIPS capacity.
How can mainframe optimization help reduce licensing costs?
Mainframe optimization reduces licensing costs by lowering the peak Rolling 4-Hour Average (R4HA). Since IBM software charges (MLC) are often calculated based on the highest peak utilization in a month, reducing MSU consumption during these peak windows directly lowers the monthly bill.
What is the role of WLM in performance tuning?
The Workload Manager (WLM) manages the distribution of system resources among competing workloads. Proper WLM calibration ensures that mission-critical transactions have the resources they need while “capping” lower-priority tasks to prevent them from driving up billable MSU peaks.
Is optimization still relevant for Tailored Fit Pricing (TFP)?
Yes. While TFP focuses on total consumption rather than peaks, optimization reduces the overall “size” of your workload. This allows you to fit more business processing into your existing container or baseline, effectively increasing your ROI and delaying the need for additional capacity purchases.
