sp_configure_peerconflictdetection (Transact-SQL)

SQL Server 2008

Configures conflict detection for a publication that is involved in a peer-to-peer transactional replication topology. For more information, see How to: Configure Conflict Detection for Peer-to-Peer Transactional Replication (Replication Transact-SQL Programming). This stored procedure is executed at the Publisher on the publication database.

Syntax

sp_configure_peerconflictdetection [ @publication= ] 'publication'
    [ , [ @action= ] 'action']
    [ , [ @originator_id= ] originator_id ]
    [ , [ @conflict_retention= ] conflict_retention ]
    [ , [ @continue_onconflict= ] 'continue_onconflict']
    [ , [ @local= ] 'local']
    [ , [ @timeout= ] timeout ]

Arguments

[ @publication=] 'publication'

Is the name of the publication for which to configure conflict detection. publication is sysname, with no default.

[ @action= ] 'action'

Specifies whether to enable or disable conflict detection for a publication. action is nvarchar(5), and can be one of the following values.

Value	Description
enable	Enables conflict detection for a publication.
disable	Disables conflict detection for a publication.
NULL (default)

[ @originator_id= ] originator_id

Specifies an ID for a node in a peer-to-peer topology. originator_id is int, with a default of NULL. This ID is used for conflict detection if action is set to enable. Specify a positive, nonzero ID that has never been used in the topology. For a list of IDs that have already been used, query the Mspeer_originatorid_history system table.

[ @conflict_retention= ] conflict_retention

Identified for informational purposes only. Not supported. Future compatibility is not guaranteed.

[ @continue_onconflict= ] 'continue_onconflict' ]

Determines whether the Distribution Agent continues to process changes after a conflict is detected. continue_onconflict is nvarchar(5) with a default value of FALSE.

Caution
We recommend that you use the default value of FALSE. When this option is set to TRUE, the Distribution Agent tries to converge data in the topology by applying the conflicting row from the node that has the highest originator ID. This method does not guarantee convergence. You should make sure that the topology is consistent after a conflict is detected. For more information, see "Handling Conflicts" in Conflict Detection in Peer-to-Peer Replication.
