sp_setsubscriptionxactseqno (Transact-SQL)

Used during troubleshooting to specify the log sequence number (LSN) of the next transaction to be applied by the Distribution Agent at the Subscriber, which enables the agent to skip a failed transaction. This stored procedure is executed at the Subscriber on the subscription database. Not supported for non-SQL Server Subscribers.

Caution note Caution

Using this stored procedure incorrectly or specifying an incorrect LSN value can cause the Distribution Agent to revert changes that were already applied at the Subscriber or skip over all remaining changes.

sp_setsubscriptionxactseqno [ @publisher = ] 'publisher' 
        , [ @publisher_db = ] 'publisher_db' 
        , [ @publication = ] 'publication' 
        , [ @xact_seqno = ] xact_seqno

[ @publisher= ] 'publisher'

Is the name of the Publisher. publisher is sysname, with no default.

[ @publisher_db= ] 'publisher_db'

Is the name of the publication database. publisher_db is sysname, with no default. For a non-SQL Server Publisher, publisher_db is the name of the distribution database.

[ @publication= ] 'publication'

Is the name of the publication. publication is sysname, with no default. When the Distribution Agent is shared by more than one publication, you must specify a value of ALL for publication.

[ @xact_seqno= ] xact_seqno

Is the LSN of the next transaction at the Distributor to be applied at the Subscriber. xact_seqno is varbinary(16), with no default.

Column name

Data type

Description

ORIGINAL XACT_SEQNO

varbinary(16)

The original LSN of the next transaction to be applied at the Subscriber.

UPDATED XACT_SEQNO

varbinary(16)

The updated LSN of the next transaction to be applied at the Subscriber.

SUBSCRIPTION STREAM COUNT

int

The number of subscription streams used during the last synchronization.

0 (success) or 1 (failure)

sp_setsubscriptionxactseqno is used in transactional replication.

sp_setsubscriptionxactseqno cannot be used in a peer-to-peer transactional replication topology.

sp_setsubscriptionxactseqno can be used to skip a specific transaction that is causing an error when applies at the Subscriber. When there is a failure and after the Distribution Agent stops, call sp_helpsubscriptionerrors (Transact-SQL) at the Distributor to retrieve the xact_seqno value of the failed transaction, and then call sp_setsubscriptionxactseqno, passing this value for xact_seqno. This will ensure that only the commands after this LSN will be processed.

Specify a value of 0 for xact_seqno to deliver all pending commands in the distribution database to the Subscriber.

sp_setsubscriptionxactseqno may fail if the Distribution Agent uses multi-subscription streams.

When this error occurs, you must run the Distribution Agent with a single subscription stream. For more information, see Replication Distribution Agent.

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