sp_configure_peerconflictdetection (Transact-SQL)

  • Článek

Applies to: SQL Server

Configures conflict detection for a publication that is involved in a peer-to-peer transactional replication topology. For more information, see Peer-to-Peer - Conflict Detection in Peer-to-Peer Replication. This stored procedure is executed at the Publisher on the publication database.

Important

You can't use sp_configure_peerconflictdetection to enable lastwriter. To change the conflict resolution of an existing replication topology, drop the publication and recreate it.

Transact-SQL syntax conventions

Syntax

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

Arguments

[ @publication = ] N'publication'

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

[ @action = ] N'action'

Specifies whether to enable or disable conflict detection for a publication. @action is nvarchar(32), 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 hasn't been used in the topology. For a list of IDs that were already 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 = ] N'continue_onconflict'

Determines whether the Distribution Agent continues to process changes after a conflict is detected. @continue_onconflict is nvarchar(5), with a default 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's the highest originator ID. This method doesn't guarantee convergence. You should make sure that the topology is consistent after a conflict is detected. For more information, see Handling Conflicts.

[ @local = ] N'local'

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

[ @timeout = ] timeout

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

Return code values

0 (success) or 1 (failure).

Remarks

sp_configure_peerconflictdetection is used in peer-to-peer transactional replication. To use conflict detection, all nodes must be running SQL Server 2008 (10.0.x) or later versions; and detection must be enabled for all nodes.

Permissions

Requires membership in the sysadmin fixed server role, or db_owner fixed database role.
