A method, a system and a computer program product for hybrid computing system management are proposed. In the method, workload information associated with a set of application server instances running in a first computing system is obtained by a server controller in response to a scaling request for changing the number of instances in the set of application server instances from a request controller. The set of application server instances serves at least one application running in a second computing system. A scaling decision indicating whether to change the number of instances in the set of application server instances is determined by a predictor based on the workload information from the server controller. The second computing system is enabled by the request controller to handle requests associated with the at least one application for the set of application server instances based on the scaling decision.

Hybrid computing system management

Data collection is provided, in which one or more affected transactions related to one or more transaction exceptions are determined. Based on one or more features of the one or more affected transactions, one or more trace features are determined. Based on the one or more trace features, a data collection rule is generated. Data of a subsequent transaction complying with the data collection rule is collected.

Data collection in transaction problem diagnostic

Provided are systems, methods, and media for concurrency conflict testing for shared resources. An example method includes identifying shared resources that are to be accessed by an application. Generating a plurality of concurrency test scenarios based on the shared resources. Analyzing a plurality of concurrency test cases to detect which concurrency test cases include a reference to the shared resources. Executing a concurrency test scenario. Performing the following while or before the concurrency test scenario is executing, obtaining analyzed concurrency test cases associated with the concurrency test scenario which referenced the shared resources, obtaining application modules pertaining to the obtained concurrency test cases, generating concurrency application modules by adding breakpoints to the obtained application modules, executing the obtained concurrency test cases until all of the obtained concurrency test cases are latched at the breakpoints, and simultaneously resuming the execution of the obtained concurrency test cases.

A computing system performs file conversion upon format expiration. A computing system evaluates a risk of expiration of a first format associated with a first format object. The computing system determines if the risk of expiration is above a threshold. The computing system identifies in response to determining the risk of expiration is above the threshold, one or more files stored in the first format for conversion. The computing system converts one or more files stored in the first format to a second format. The computing system saves the one or more files in the second format.
