sp_adddistributor (Transact-SQL)

Creates an entry in the sys.sysservers table (if there is not 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 is also executed at the Publisher from the master database to register the remote distributor.

Syntax

sp_adddistributor [ @distributor= ] 'distributor' 
    [ , [ @heartbeat_interval= ] heartbeat_interval ] 
    [ , [ @password= ] 'password' ] 
    [ , [ @from_scripting= ] from_scripting ]

Arguments

  • [ @distributor=] 'distributor'
    Is 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.

  • [ @heartbeat_interval=] heartbeat_interval
    Is 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=] 'password']
    Is the password of the distributor_admin login. password is sysname, with a default of NULL. If 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.

    Security noteSecurity Note

    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

-- Install the Distributor and the distribution database.
DECLARE @distributor AS sysname;

DECLARE @publicationDB AS sysname;
-- Specify the Distributor name.
SET @distributor = $(DistPubServer);
-- Specify the distribution database.
SET @distributionDB = N'distribution';
-- Specify the Publisher name.
SET @publisher = $(DistPubServer);
-- Specify the replication working directory.
SET @directory = N'\\' + $(DistPubServer) + '\repldata';
-- Specify the publication database.
