    摘要: An approach to improving performance of a target system is disclosed. The approach may involve determining how similar a target system being considered is to other systems in use by other clients. For each of these other separate systems, the approach may involve determining the differences between the performance of the target system and the performance of the separate system, accounting for the level of similarity. A report can be generated that identifies performance values of the target system that are outside an acceptable range, which is based on the performance of the other separate systems. Based on this report, the administrator of the target system can consider configuration changes and upgrades to improve performance of the target system.

    摘要: A method for selectively generating trace data is disclosed. Such a method includes executing a first module on a processor. The processor is operably coupled to a memory storing the first module and one or more branch modules. The method further includes detecting the execution of an instruction of the first module to execute a branch module. In response to detecting execution of the instruction, traces of branch modules subsequently executed by the processor are generated. Upon detecting a return of execution by the processor to the first module, the generation of traces is terminated and a trace report is generated. A corresponding apparatus and computer program product are also disclosed herein.

    摘要: Various embodiments for adaptive reorganization of a virtual storage access method (VSAM) data set are provided. In one exemplary embodiment, upon each control interval (CI) split of a plurality of CI splits occurring over a period of time, historical data including a key value for a record causing each CI split is recorded in a data repository. The historical data is analyzed with a predictive algorithm to determine an amount of free space to be allocated to each of a plurality of control intervals generated pursuant to the adaptive reorganization. The predictive algorithm allocates a greater percentage of the free space to a first location of the VVDS having a larger proportion of historically placed key values than a second location of the VVDS having a smaller proportion of the historically placed key values.

    摘要: An approach to providing auto recovery of data sets in volumes. When an error condition results from an attempt to access an unintentionally deleted data set, an event is generated and sent to other systems with access to the volume in which the data set existed. The volume is also locked to prevent corruption during the recovery process. A system that has the unintentionally deleted data set open retrieves location information for the data set from control blocks in the system's memory. This location information is used to build a new entry for the data set in the VTOC for the volume. When the data set is thus recovered, the data set is validated, the lock removed, and the data set is made available to the systems sharing the volume.
