sp_repldone (Transact-SQL)

  • Άρθρο

Applies to: SQL Server Azure SQL Managed Instance

Updates the record that identifies the last distributed transaction of the server. This stored procedure is executed at the Publisher on the publication database.

Caution

If you execute sp_repldone manually, you can invalidate the order and consistency of delivered transactions. You should only use sp_repldone for troubleshooting replication as directed by an experienced replication support professional.

Transact-SQL syntax conventions

Syntax

sp_repldone [ @xactid = ] xactid
    , [ @xact_seqno = ] xact_seqno
    [ , [ @numtrans = ] numtrans ]
    [ , [ @time = ] time ]
    [ , [ @reset = ] reset ]
[ ; ]

Arguments

[ @xactid = ] xactid

The log sequence number (LSN) of the first record for the last distributed transaction of the server. @xactid is binary(10), with no default.

[ @xact_seqno = ] xact_seqno

The LSN of the last record for the last distributed transaction of the server. @xact_seqno is binary(10), with no default.

[ @numtrans = ] numtrans

The number of transactions distributed. @numtrans is int, with no default.

[ @time = ] time

The number of milliseconds, if provided, needed to distribute the last batch of transactions. @time is int, with no default.

[ @reset = ] reset

The reset status. @reset is int, with no default.

  • If 1, all replicated transactions in the log are marked as distributed.
  • If 0, the transaction log is reset to the first replicated transaction and no replicated transactions are marked as distributed.

@reset is valid only when both @xactid and @xact_seqno are NULL.

Return code values

0 (success) or 1 (failure).

Remarks

sp_repldone is used in transactional replication.

sp_repldone is used by the log reader process to track which transactions have been distributed.

With sp_repldone, you can manually tell the server that a transaction has been replicated (sent to the Distributor). It also allows you to change the transaction marked as the next one awaiting replication. You can move forward or backward in the list of replicated transactions. (All transactions less than or equal to that transaction are marked as distributed.)

The required parameters @xactid and @xact_seqno can be obtained by using sp_repltrans or sp_replcmds.

This procedure can be used in emergency situations to allow truncation of the transaction log when transactions pending replication are present. For more information, see the Examples section.

Permissions

Members of the sysadmin fixed server role or the db_owner fixed database role can execute sp_repldone.

Examples

When @xactid is NULL, @xact_seqno is NULL, and @reset is 1, all replicated transactions in the log are marked as distributed. This is useful when there are replicated transactions in the transaction log that are no longer valid and you want to truncate the log, for example:

EXEC sp_repldone
    @xactid = NULL,
    @xact_seqno = NULL,
    @numtrans = 0,
    @time = 0,
    @reset = 1;
