Method, system, and program for performing processing associated with transaction execution in a computing environment (restricted instructions in transaction execution)

摘要

A method, system, and program for restricted instructions in transaction execution. Prohibiting restricted instructions from being executed within a transaction. There are classes of instructions that are restricted regardless of the type of transaction, ie, constrained or unconstrained. There are instructions that are restricted only in a constrained transaction, and there are instructions that are selectively restricted for a given transaction based on the control specified in the instruction used to initiate the transaction.
