Remarks

sp_requestpeerresponse is used in peer-to-peer transactional replication.

sp_requestpeerresponse is used to ensure that all commands have been received by all other nodes before restoring a database published in a peer-to-peer topology. It is also used when replicating data definition language (DDL) changes made while a node was offline to estimate when these changes arrive at the other nodes.

sp_requestpeerresponse cannot be executed within a user-defined transaction.

Permissions

Only members of the sysadmin fixed server role or the db_owner fixed database role can execute sp_requestpeerresponse.
