sp_addpushsubscription_agent (Transact-SQL)

Adds a new scheduled agent job used to synchronize a push subscription to a transactional publication. This stored procedure is executed at the Publisher on the publication database.

Uwaga dotycząca zabezpieczeń

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. For a non-SQL Server Subscriber, specify a value of (default destination) for subscriber_db.

• [ @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. 0 specifies SQL Server Authentication. 1 specifies Windows Authentication.

  Uwaga dotycząca zabezpieczeń
  For queued updating subscriptions, use SQL Server Authentication for connections to Subscribers, and specify a different account for the connection to each Subscriber. For all other subscriptions, use Windows Authentication.

• [ @subscriber_login =] 'subscriber_login'
  Is the Subscriber login to use when connecting to a Subscriber when synchronizing. subscriber_login is sysname, with a default of NULL.

• [ @subscriber_password =] 'subscriber_password'
  Is the Subscriber password. 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.

  Uwaga dotycząca zabezpieczeń
  Do not use a blank password. Use a strong 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.

• [ @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 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.

  Uwaga dotycząca zabezpieczeń
  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 will be 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 Distribution 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 (default)	Autostart
  128	Recurring

  [!UWAGA]

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

• [ @frequency_interval = ] frequency_interval
  Is the value to apply to the frequency set by frequency_type. frequency_interval is int, with a default of 1.

• [ @frequency_relative_interval = ] frequency_relative_interval
  Is the date of the Distribution 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 (default)	First
  2	Second
  4	Third
  8	Fourth
  16	Last

• [ @frequency_recurrence_factor = ] frequency_recurrence_factor
  Is the recurrence factor used by frequency_type. frequency_recurrence_factor is int, with a default of 0.

• [ @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 (default)	Minute
  8	Hour

• [ @frequency_subday_interval = ] frequency_subday_interval
  Is the interval for frequency_subday. frequency_subday_interval is int, with a default of 5.

• [ @active_start_time_of_day = ] active_start_time_of_day

• [ @active_start_date = ] active_start_date
  Is the date when the Distribution Agent is first scheduled, formatted as YYYYMMDD. active_start_date is int, with a default of 0.

• [ @active_end_date = ] active_end_date
  Is the date when the Distribution Agent stops being scheduled, formatted as YYYYMMDD. active_end_date is int, with a default of 99991231.
