Applies to: SQL Server Azure SQL Managed Instance

Creates a new distribution database and installs the Distributor schema. The distribution database stores procedures, schema, and metadata used in replication. This stored procedure is executed at the Distributor on the master database in order to create the distribution database, and install the necessary tables and stored procedures required to enable the replication distribution.

Arguments

[ @database = ] N'database'

The name of the distribution database to be created. @database is sysname, with no default. If the specified database already exists and isn't already marked as a distribution database, then the objects needed to enable distribution are installed, and the database is marked as a distribution database. If the specified database is already enabled as a distribution database, an error is returned.

[ @data_folder = ] N'data_folder'

The name of the directory used to store the distribution database data file. @data_folder is nvarchar(255), with a default of NULL. If NULL, the data directory for that instance of SQL Server is used, for example, C:\Program Files\Microsoft SQL Server\MSSQL16.MSSQLSERVER\MSSQL\Data.

[ @data_file = ] N'data_file'

The name of the database file. @data_file is nvarchar(255), with a default of NULL. If NULL, the stored procedure constructs a file name using the database name.

[ @data_file_size = ] data_file_size

The initial data file size in megabytes (MB). @data_file_size is int, with a default of 5, which is 5 MB.

[ @log_folder = ] N'log_folder'

The name of the directory for the database log file. @log_folder is nvarchar(255), with a default of NULL. If NULL, the data directory for that instance of SQL Server is used (for example, C:\Program Files\Microsoft SQL Server\MSSQL16.MSSQLSERVER\MSSQL\Data).

[ @log_file = ] N'log_file'

The name of the log file. @log_file is nvarchar(255), with a default of NULL. If NULL, the stored procedure constructs a file name using the database name.

[ @log_file_size = ] log_file_size

The initial log file size in megabytes (MB). @log_file_size is int, with a default of 0, which creates the file using the smallest log file size allowed by the Database Engine.

[ @min_distretention = ] min_distretention

The minimum retention period, in hours, before transactions are deleted from the distribution database. @min_distretention is int, with a default of 0.

[ @max_distretention = ] max_distretention

The maximum retention period, in hours, before transactions are deleted. @max_distretention is int, with a default of 72. Subscriptions that haven't received replicated commands, and that are older than the maximum distribution retention period, are marked as inactive and need to be reinitialized. Error number 21011 is issued for each inactive subscription. A value of 0 means that replicated transactions aren't stored in the distribution database.

[ @history_retention = ] history_retention

The number of hours to retain history. @history_retention is int, with a default of 48, which means two days.

[ @security_mode = ] security_mode

The security mode to use when connecting to the Distributor. @security_mode is int, with a default of 1.

0 specifies SQL Server authentication
1 specifies Windows authentication

[ @login = ] N'login'

The login name used when connecting to the Distributor to create the distribution database. @login is sysname, with a default of NULL. @login is required if @security_mode is set to 0.

[ @password = ] N'password'

The password used when connecting to the Distributor. @password is sysname, with a default of NULL. @password is required if @security_mode is set to 0.

[ @createmode = ] createmode

@createmode is int, and can be one of the following values.

Value	Description
`0`	Identified for informational purposes only. Not supported. Future compatibility is not guaranteed.
`1` (default)	`CREATE DATABASE` or use existing database and then apply the `instdist.sql` file to create replication objects in the distribution database.
`2`	Identified for informational purposes only. Not supported. Future compatibility is not guaranteed.

[ @from_scripting = ] from_scripting

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

[ @deletebatchsize_xact = ] deletebatchsize_xact

Specifies the batch size to be used during cleanup of expired transactions from the MSRepl_Transactions tables. @deletebatchsize_xact is int, with a default of 5000.

Applies to: SQL Server 2012 (11.x) with Service Pack 4, SQL Server 2016 (13.x) with Service Pack 2, SQL Server 2017 (14.x), and later versions.

[ @deletebatchsize_cmd = ] deletebatchsize_cmd

Specifies the batch size to be used during cleanup of expired commands from the MSRepl_Commands tables. @deletebatchsize_cmd is int, with a default of 2000.

Applies to: SQL Server 2012 (11.x) with Service Pack 4, SQL Server 2016 (13.x) with Service Pack 2, SQL Server 2017 (14.x), and later versions.

Return code values

0 (success) or 1 (failure).

Remarks

sp_adddistributiondb is used in all types of replication. However, this stored procedure only runs at a distributor.

You must configure the distributor by executing sp_adddistributor before executing sp_adddistributiondb.

Run sp_adddistributor prior to running sp_adddistributiondb.

Examples

This script uses SQLCMD scripting variables and must run in SQLCMD mode. The variables are in the form $(MyVariable). For information about how to use scripting variables on the command line and in SQL Server Management Studio, see the Executing Replication Scripts.
