Abstract:
Embodiments relate to dynamic management of a transaction retry indication. One aspect is a system that includes a transactional facility configured to support transactions that effectively delay committing stores to memory or results to an architectural state until transaction completion, and a processor configured to identify a transaction abort reason associated with an aborted transaction of an initiating program. Transaction success and transaction abort history are tracked. Based on determining by the processor that the transaction abort reason was caused by the initiating program, a retry indication is assigned based on a static mapping of the transaction abort reason. Based on determining by the processor that the transaction abort reason was not caused by the initiating program, the retry indication is assigned based on a retry process using the transaction abort reason, the transaction abort history, and a current processor configuration.
