sp_requestpeerresponse (Transact-SQL)

When executed from a node in a peer-to-peer topology, this procedure requests a response from every other node in the topology. By executing this procedure and reviewing the corresponding responses, you can guarantee that all previous commands have been delivered to the responding nodes. This stored procedure is executed at the requesting node on any database.

sp_requestpeerresponse [ @publication = ] 'publication'
    [ , [ @description = ] 'description'

    Is the name of the publication in a peer-to-peer topology for which the status is being verified. publication is sysname, with no default.

  • [ @description= ] 'description'
    User-defined information that can be used to identify individual status requests. description is nvarchar(4000), with a default of NULL.

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.
