First Claim
Patent Images
1. A computer program product for controlling execution of transactions in a computing environment, said computer program product comprising:
- at least one non-transitory computer readable storage medium readable by at least one processing circuit and storing instructions for performing a method comprising;
initiating a transaction in a computing environment; and
determining, by a processor, whether the transaction is to be aborted, the determining employing one or more controls of a control register used by the processor, the one or more controls to indicate whether transactions are to be randomly selected to be aborted for testing purposes to debug certain types of abort conditions.

Abstract
Task specific diagnostic controls are provided to facilitate the debugging of certain types of abort conditions. The diagnostic controls may be set to cause transactions to be selectively aborted, allowing a transaction to drive its abort handler routine for testing purposes. The controls include, for instance, a transaction diagnostic scope and a transaction diagnostic control. The transaction diagnostic scope indicates when the transaction diagnostic control is to be applied, and the transaction diagnostic control indicates whether transactions are to selectively aborted.

11. A computer system for controlling execution of transactions in a computing environment, said computer system comprising:
-
a memory; and a processor in communication with the memory, wherein the processor is configured to perform a method, said method comprising; determining, by the processor, whether a transaction initiated in the computing environment is to be aborted, the determining employing one or more controls of a control register used by the processor, the one or more controls to indicate whether transactions are to be randomly selected to be aborted for testing purposes to debug certain types of abort conditions. - View Dependent Claims (12, 13, 14, 15)
