The SMF 89 record type stores the CPU of each registered Sub-Capacity product over time. This is useful for finding out:
- which address spaces are registering which products on which systems
- product version
- product qualifiers (which relates to subsystem names for DB2 and MQ and components for IMS)
- CPU that is consumed by each product (used in specialized licensing programs like zCAP)
Tracking Software Version Upgrade Progress
One practical use of the SMF 89 data is to track the progress of a migration of a software version upgrade. As shown in the video, when a migration is underway from CICS version 5.3 To 5.5, the SMF 89 records give us insight into where the activity is occurring. In the video we see that most of the activity is happening on 5.5, but some activity is still happening on 5.3. This data also makes it easy to identify which the CICS regions are executing which versions.
Avoid MLC Charges on Unintended Usage
Another practical use of SMF 89 data is to help avoid being charged MLC costs for unintended data usage. Under MLC rules, any execution of a product on a particular system in a given hour causes all the MSUs for that system to be chargeable for that product. There can be instances when controls to limit execution of products to specified systems don’t work as intended.
We’ve seen TSO users executing the IMS BTS batch terminal simulator capability for unit testing result in IMS to be charged for MSUs on an unintended system. So usage data by product in the SMF 30 Address Space Records can be helpful in tracking down such unintended usage.
No-obligation MLC Reduction Assessment
Software costs consistently dominate the budget for mainframe installations of which processor cache efficiency can have a significant role in reducing. However, according to our recent survey, 88% of sites have not optimized their processor cache utilization. Get in touch with one of our experts to determine if your site has potential MLC savings.
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.
Despite the benefits - zIIP processors are typically less expensive to purchase and also run at full speed on sub-capacity CPU models - zIIP processor usage may not always be what one hopes for.
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.
