sp_adddistributor (Transact-SQL)

Applies to: SQL Server Azure SQL Managed Instance

Creates an entry in the sys.servers table (if there isn't one), marks the server entry as a Distributor, and stores property information. This stored procedure is executed at the Distributor on the master database to register and mark the server as a distributor. In the case of a remote distributor, it's also executed at the Publisher from the master database to register the remote distributor.

Transact-SQL syntax conventions


    [ @distributor = ] N'distributor'
    [ , [ @heartbeat_interval = ] heartbeat_interval ]
    [ , [ @password = ] N'password' ]
    [ , [ @from_scripting = ] from_scripting ]
[ ; ]


[ @distributor = ] N'distributor'

The distribution server name. @distributor is sysname, with no default. This parameter is only used if setting up a remote Distributor. It adds entries for the Distributor properties in the msdb..MSdistributor table.


Server name can be specified as <Hostname>,<PortNumber>. You may need to specify the port number for your connection when SQL Server is deployed on Linux or Windows with a custom port, and the SQL Server browser service is disabled. The use of custom port numbers for remote distributor applies to SQL Server 2019 (15.x) only.

[ @heartbeat_interval = ] heartbeat_interval

The maximum number of minutes that an agent can go without logging a progress message. @heartbeat_interval is int, with a default of 10 minutes. A SQL Server Agent job is created that runs on this interval to check the status of the replication agents that are running.

[ @password = ] N'password'

The password of the distributor_admin login. @password is sysname, with a default of NULL. If the password is NULL or an empty string, @password is reset to a random value. The password must be configured when the first remote distributor is added. distributor_admin login and @password are stored for linked server entry used for a distributor RPC connection, including local connections. If distributor is local, the password for distributor_admin is set to a new value. For Publishers with a remote Distributor, the same value for @password must be specified when executing sp_adddistributor at both the Publisher and Distributor. sp_changedistributor_password can be used to change the Distributor password.


When possible, prompt users to enter security credentials at runtime. If you must store credentials in a script file, you must secure the file to prevent unauthorized access.

[ @from_scripting = ] from_scripting

@from_scripting is bit, with a default of 0. Identified for informational purposes only. Not supported. Future compatibility is not guaranteed.

Return code values

0 (success) or 1 (failure).


sp_adddistributor is used in snapshot replication, transactional replication, and merge replication.
