Is this z/OS workload change normal?
Change Detection allows analysts to automatically detect workload and application changes, saving them countless hours of manual labor and intensive scrutiny while trying to determine the significance of changes
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.
Don’t Overlook Supply Chain Disruptions in Your Disaster Recovery Plan
Learn how to mitigate the risk posed by supply chain disruptions by taking a closer look at your disaster recovery plan.
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.
Troubleshooting Oversubscribed SAN Fabric Inter-Switch Links (ISL’s)
If not resolved quickly, SAN Fabric bottlenecks (starting with the Inter-Switch Links) often result in buffer credit shortages which can lead to performance delays.
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.
