1. A computer implemented method for collecting memory operand access characteristics during transactional execution (TX) of a transaction, the method comprising:

  • initiating, by a processor, a transactional execution of a set of instructions in a transaction of a program;

    collecting, by the processor, memory operand access characteristics of the set of instructions during the transactional execution;

    storing, by the processor, the memory operand access characteristics upon a termination of the transactional execution of the set of instructions; and

    wherein the initiating is performed by execution of a TBEGIN instruction in the program, by the processor, the TBEGIN instruction specifying a parameter, the parameter designating a storage location for the storing of the memory operand access characteristics.
