Vote Read-Only Response to a Sync Point Operation (249)

This option set improves performance of sync point operations by allowing the local LU to vote read-only when none of the protected resources in its part of the distributed transaction have been changed. This option set includes the VOTE_READ_ONLY_PERMITTED parameter of the ATBSSO4 call, and affects the return code to the SRRCMIT or SRRBACK verb.
