The system and techniques described herein include receiving a transaction report from a log dataset, where the transaction report includes a class identifier (ID) for each of the transactions, a transaction execution count, and a total transaction response time. A first listing of the transactions is generated. An average number of unique transactions assigned to all of the classes and an average transaction execution count are calculated. A second listing of the transactions is generated that includes all of the transactions for the class IDs where the count of unique transactions assigned to the class is greater than the average number of unique transactions assigned to all of the classes. For each class ID and transaction name, the second listing is updated to identify one or more of the transactions as candidate transactions for running in a P-WFI region when the conditions are met.

Systems and methods for isolating transactions to a pseudo-wait-for-input region

System and techniques for determining an optimal number of regions in an IMS system include receiving a transaction report from a log dataset. A first table is generated from the transaction report, where the first table includes a class identified by a class identifier (ID), a number of regions the class is assigned, and a total percent region occupancy by the class. Classes ineligible to be shut down are identified based on a set of criteria and the classes ineligible to be shut down are eliminated. For each remaining class assigned to a threshold number of regions, candidate regions from the threshold number of regions eligible for shut down are identified and remaining regions from the threshold number of regions that can handle a workload from the candidate regions eligible for shut down are identified, where the remaining regions represent the optimal number of regions in the IMS system.

Optimizing the number of IMS dependent regions

A technique for collecting and correlating locking data collects and correlates information on a plurality of programs waiting on or holding a plurality of resources in a multi-computer database system. The technique identifies a program executing on one computer of the multi-computer database system that is waiting on a resource. The technique also identifies a second program, executing on another computer, as the ultimate holder of the resource. An operator display screen displays information corresponding to the first program and the second program. The operator display screen may be switched between a multiline display format and a single line display format. The collection, identification, and display of the locking data is performed periodically, to allow the operator to discover locking problems and take a desired corrective action.
