A conversion operation is performed which includes a plurality of conversion actions. A conversion action includes processing an instruction to convert selected data from a source data type to a target data type. The processing includes determining whether a data type indicated using the instruction is a valid data type for a select machine. The data type is a selected data type selected from the source data type or the target data type. The selected data is converted from the source data type to the target data type, based on determining that the data type is a valid data type for the select machine. An indicator is set to a select value to indicate the data type is an invalid data type, based on determining that the data type is an invalid data type for the select machine. The indicator is checked at an end of the conversion operation.

Detection of invalid machine-specific data types during data conversion

A computer-implemented method includes monitoring, by an agent, resource consumption at a system running at an on-premises data center, where the agent is embedded into the system. Compliance data is determined by measuring, by the agent, the resource consumption according to one or more cost factors of a consumption-based pricing agreement. The compliance data is useable to determine a consumption-based price of operating the system according to the consumption-based pricing agreement.

Ensuring compliance in on-premise compute models

According to one or more embodiments of the present invention, a computer-implemented method includes allocating a set of computing resources to a first partition from a plurality of partitions in a computer server, and monitoring a usage duration of the set of computing resources by the first partition. The method further includes generating a billing statement based on the usage duration of the computing resources by the first partition. The method further includes detecting an abnormal event in operation of the first partition and adjusting one or more settings of the set of computing resources to increase processing capacity associated with the first partition to complete the abnormal event. The method further includes monitoring a first usage duration of the computing resources during completion of the abnormal event and adjusting the usage duration of based on the first usage duration, and adjusting the billing statement using the adjusted usage duration.

Increasing processing capacity of processor cores during initial program load processing

Systems and methods for tracking computing resources are provided. Aspects include receiving, by a workload manager, a workload, wherein the workload is executable on a customer machine, and wherein the customer machine comprises a plurality of computing resources. The workload is analyzed to determine a workload profile. A token associated with the workload is received and associated with the workload profile. The token is authenticated and the workload is executed based at least in part on authentication of the token.

Tracking usage of computing resources

A file with an exclusive serialization is allocated. The exclusive serialization associated with the newly allocated file is transformed into a shared serialization. The file with the shared serialization is allocated as shared resource for a multisystem environment.

Sharing files in a multisystem environment

Embodiments of the present invention provide systems, methods, and computer program products for managing requests for acquiring one or more resources in a computing environment. In one embodiment, successful acquisition of the one or more resources is determined. Embodiments of the present invention provide systems, methods, and computer program products for initiating a synchronous request to acquire the one or more resources, responsive to determining that the acquisition of the one or more resources is not successful.

Management of asynchronous and synchronous resource requests

Embodiments of the present invention provide methods, program products, and systems for reusing a duplex storage medium resource. Embodiments of the present invention can be used to transition between duplex media by determining that a prior transition from a first duplex storage media to a second duplex storage media is being performed and reinitializing the second duplex storage media to receive, for storage, duplex data transferred from the first duplex storage media. Embodiments of the present invention can be used to reduce potential collisions with naming conventions and reduce unwanted delay that results in forcing an offload by managing the recovery medium and keeping it available through policy based medium changes.

Reusing a duplexed storage resource

Managing requests for acquiring resources in a computing environment. A first request to acquire resources is received. Whether the resources have been pre-acquired is determined. If the resources have not been pre-acquired, a token registering interest of a first thread in the first request is subscribed to. If the acquisition of the resources is not successful, whether a prior synchronous request has been initiated by a thread for the first request is determined. If a prior synchronous request has not been initiated, a synchronous request is initiated to acquire the resources. If the resources have not been pre-acquired for a second received request, an interest is registered of a second thread in the first request using the token. If the acquisition of the one or more resources is successful, a thread is notified of the successful acquisition, and the interest of the second thread is unregistered in the first request.

A method and computer program product for testing a system logger. Randomized input is provided into a logging facility and automated testing of the logging facility is performed in a multi-processing environment. Self-verification of data retrieved from the logging facility is performed to ensure no data loss occurs due to external system events or failures driven by a test tool. Real-time analysis of results received is performed by the test tool based on the randomized input into the logging facility. First failure data is captured and self-verification of results of a data recovery operation of the logging facility is performed in a disaster recovery scenario. Self-verification includes writing log blocks of random sizes to the log stream, iteratively forcing log data to be offloaded from primary storage to secondary storage, iteratively updating log stream attributes, and iteratively swapping duplexing modes.
