Mainframe encryption causes higher demand in TCP/IP address space
Many shops are using IBM’s pervasive encryption to protect their mainframe's integrity, but how do we get in front of the mainframe impacts or know which encryption methods might meet security requirements at lower cost?
Stretched in 2020?
This year has certainly stretched everyone. Learn some ways to overcome some new and unexpected challenges that likely weren’t even on your radar in January.
Deriving Insights from SMF 116 MQ Accounting Data
MQ Accounting records are often considered to be too expensive, both in CPU overhead and SMF record volume. However, we believe that these concerns may be overstated.
AI: Too Much of a Good Thing
Solution providers will continue to entice us with bigger and better real-time analytics. Some of these should be employed, but first try to understand the logic you may be activating when you implement.
Understanding How Logical Workloads Behave On Physical Hardware
If you find elevated response time on a logical volume, how do you know which physical drives may be causing it?
4 Benefits of Implementing TS7700’s New Microcode Compression
Implementing the TS7700 microcode-based compression algorithms can have benefits beyond better compression. The CPU algorithms allow host jobs to run faster and improve replication time.
Deriving Insights from SMF 115 MQ Statistics Data
SMF 115 MQ Statistics records report metrics at the MQ queue manager level. These records are lightweight and have negligible CPU cost, so sites typically generate MQ Statistics records on an ongoing basis.
Understanding Physical Sequential Datasets
Oftentimes it is sufficient to analyze I/O performance without needing to understand the datasets. The SMF 42 records are useful to obtain a deeper understanding of the datasets and the applications that are using the storage.
Sub-Capacity Reporting Tool (SCRT) Filtering Capabilities & Benefits
The goal of analyzing Sub-Capacity Reporting Tool (SCRT) usage is to ultimately manage and reduce your MSU usage, and thus MLC costs.
Getting to Know Your WebSphere for z/OS Workload
There are many areas of WebSphere that can leave even a seasoned z/OS performance specialist scratching their head. The SMF 120-9 records give us a great way to measure and understand our WebSphere workloads like never before.
Avoid Inefficiencies with Store Into Instruction Stream (SIIS) Assessments
Programs that store data into the instruction stream introduce major inefficiencies into CPU performance. Updating SIIS programs can result in significant reduction of CPU utilization.
Reduce Latency and Lower Demand as You Create the Capacity Plan
Mainframe capacity planning is an important budgetary input. If you ensure your performance is in order or have mentioned some efficiency recommendations, you will help keep your organization lean and productive.
