sp_addmergepushsubscription_agent (Transact-SQL)

SQL Server 2012

Adds a new agent job used to schedule synchronization of a push subscription to a merge publication. This stored procedure is executed at the Publisher on the publication database.

Security Note
When configuring a Publisher with a remote Distributor, the values supplied for all parameters, including job_login and job_password, are sent to the Distributor as plain text. You should encrypt the connection between the Publisher and its remote Distributor before executing this stored procedure. For more information, see Enable Encrypted Connections to the Database Engine (SQL Server Configuration Manager).

Arguments

[ @publication = ] 'publication'

Is the name of the publication. publication is sysname, with no default.

[ @subscriber = ] 'subscriber'

Is the name of the Subscriber. subscriber is sysname, with a default of NULL.

[ @subscriber_db = ] 'subscriber_db'

Is the name of the subscription database. subscriber_db is sysname, with a default of NULL.

[ @subscriber_security_mode = ] subscriber_security_mode

Is the security mode to use when connecting to a Subscriber when synchronizing. subscriber_security_mode is int, with a default of 1. If 0, specifies SQL Server Authentication. If 1, specifies Windows Authentication.

[ @subscriber_login = ] 'subscriber_login'

Is the Subscriber login to use when connecting to a Subscriber when synchronizing. subscriber_login is required if subscriber_security_mode is set to 0. subscriber_login is sysname, with a default of NULL.

[ @subscriber_password = ] 'subscriber_password'

Is the Subscriber password for SQL Server Authentication. subscriber_password is required if subscriber_security_mode is set to 0. subscriber_password is sysname, with a default of NULL. If a subscriber password is used, it is automatically encrypted.

Security 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.

[ @publisher_security_mode = ] publisher_security_mode

Is the security mode to use when connecting to a Publisher when synchronizing. publisher_security_mode is int, with a default of 1. If 0, specifies SQL Server Authentication. If 1, specifies Windows Authentication.

[ @publisher_login = ] 'publisher_login'

Is the login to use when connecting to a Publisher when synchronizing. publisher_login is sysname, with a default of NULL.

[ @publisher_password = ] 'publisher_password'

Is the password used when connecting to the Publisher. publisher_password is sysname, with a default of NULL.

Security 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.

[ @job_login = ] 'job_login'

Is the login for the Windows account under which the agent runs. job_login is nvarchar(257), with a default value of NULL. This Windows account is always used for agent connections to the Distributor and for connections to the Subscriber and Publisher when using Windows Integrated authentication.

[ @job_password = ] 'job_password'

Is the password for the Windows account under which the agent runs. job_password is sysname, with no default.

Security 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.

[ @job_name = ] 'job_name'

Is the name of an existing agent job. job_name is sysname, with a default value of NULL. This parameter is only specified when the subscription is synchronized using an existing job instead of a newly created job (the default). If you are not a member of the sysadmin fixed server role, you must specify job_login and job_password when you specify job_name.

[ @frequency_type = ] frequency_type

Is the frequency with which to schedule the Merge Agent. frequency_type is int, and can be one of the following values.

Value	Description
1	One time
2	On demand
4	Daily
8	Weekly
16	Monthly
32	Monthly relative
64	Autostart
128	Recurring
NULL (default)

Note
Specifying a value of 64 causes the Merge Agent to run in continuous mode. This corresponds to setting the -Continuous parameter for the agent. For more information, see Replication Merge Agent.

[ @frequency_interval = ] frequency_interval

The days that the Merge Agent runs. frequency_interval is int, and can be one of the following values.

Value	Description
1	Sunday
2	Monday
3	Tuesday
4	Wednesday
5	Thursday
6	Friday
7	Saturday
8	Day
9	Weekdays
10	Weekend days
NULL (default)

[ @frequency_relative_interval = ] frequency_relative_interval

Is the date of the Merge Agent. This parameter is used when frequency_type is set to 32 (monthly relative). frequency_relative_interval is int, and can be one of the following values.

Value	Description
1	First
2	Second
4	Third
8	Fourth
16	Last
NULL (default)

[ @frequency_recurrence_factor = ] frequency_recurrence_factor

Is the recurrence factor used by frequency_type. frequency_recurrence_factor is int, with a default of NULL.

[ @frequency_subday = ] frequency_subday

Is how often to reschedule during the defined period. frequency_subday is int, and can be one of the following values.

Value	Description
1	Once
2	Second
4	Minute
8	Hour
NULL (default)

[ @frequency_subday_interval = ] frequency_subday_interval

[ @active_end_time_of_day = ] active_end_time_of_day

Is the time of day when the Merge Agent stops being scheduled, formatted as HHMMSS. active_end_time_of_day is int, with a default of NULL.

[ @active_start_date = ] active_start_date

Is the date when the Merge Agent is first scheduled, formatted as YYYYMMDD. active_start_date is int, with a default of NULL.

[ @active_end_date = ] active_end_date

Is the date when the Merge Agent stops being scheduled, formatted as YYYYMMDD. active_end_date is int, with a default of NULL.

[ @enabled_for_syncmgr = ] 'enabled_for_syncmgr'

Specifies if the subscription can be synchronized through Windows Synchronization Manager. enabled_for_syncmgr is nvarchar(5), with a default of FALSE.

If true, the subscription is registered with Synchronization Manager and can be synchronized without starting SQL Server Management Studio.

Return Code Values

0 (success) or 1 (failure)
