Abstract: Aspects of the invention include methods, systems and computer program products for identifying interaction software defects. Aspects include singly executing a first testcase at a normal processing speed and singly executing a second testcase at the normal processing speed. Aspects also include simultaneously executing the first testcase at a first processing speed and a second testcase at a second processing speed. Based on determining the single and simultaneous testcase results do not match, aspects further include creating an error notification.

Abstract: A computer-implemented method for proactive change verification is provided. Aspects include analyzing runtime execution characteristics from a plurality of base activity metrics and a plurality of experimental activity metrics and creating a plurality of activity pairs wherein each activity pair comprises a base activity metric and its corresponding experimental activity metric. Aspects also include identifying significant activity pairs from the plurality of activity pairs wherein the experimental activity significantly deviates from its corresponding base activity and classifying significant activity pairs by deviation type. Aspects further include sorting activity pairs by their impact and removing activity pairs that have an impact of less than a threshold amount, wherein the threshold amount is based on the deviation type.

Abstract: A source code defining record structure of data is received. The source code includes data tags which provide information for processing to be performed on the data. Data tagging metadata is generated based on the source code, and the data tagging metadata includes record structure information and the data tags. And data is processed according to the data tagging metadata.

Abstract: A computer-implemented method for diagnosing workload performance problems in computer servers includes measuring resource metrics. The method further includes aggregating resource metrics for each consumed resource, and aggregating resource and non-resource activity metrics for each consumer. The method further includes generating condensed diagnostic data, on a synchronized, regular interval with one or more most significant consumed resource names and corresponding consumed resource metrics. Generating the condensed diagnostic data includes grouping consumers into buckets based on bucket and consumer attributes, aggregating resource and non-resource consumer activity metrics across all consumers in each bucket, and including one or more worst offending consumer names with corresponding resource and non-resource consumer activity metrics in each bucket. The condensed diagnostic data with the most significant consumed resources and bucket contents is recorded.

Abstract: A computer-implemented method for diagnosing workload performance problems in computer servers includes measuring activity metrics. The method further includes aggregating activity metrics for each user. The method further includes generating condensed diagnostic data for identifying workload performance problems on a synchronized, regular interval. Generating the diagnostic data includes grouping users into buckets based on bucket and user attributes. Generating the diagnostic data includes aggregating activity metrics across all users in each bucket. Generating the diagnostic data includes including one or more most significant users and corresponding activity metrics for each activity in each bucket, and recording bucket contents. Diagnostic data can be generated in a human consumable form for human analysis or in a machine consumable form for machine analysis through machine learning.

Abstract: A computer-implemented method for dynamic workload bucket reassignment in a system processor includes grouping a plurality of like workloads together via a common workload attribute. The processor calculates an aggregate use of a resource across all of the workloads, and creates a finite number of buckets. The processor then assigns a target resource use for each of the finite number of buckets, and assigns workloads with a same workload attribute value to a bucket of the finite number of buckets. The workload attribute values are distributed across a plurality of the finite number of buckets such that each bucket has a unique nonintersecting range and an aggregate workload resource use in each bucket near a bucket target resource use.
