sp_addpushsubscription_agent (Transact-SQL)

Artigo
12/03/2008

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.

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 Encrypting Connections to SQL Server.

Arguments

[ @subscriber =] 'subscriber'
Is the name of the Subscriber. subscriber is sysname, with a default of NULL.

[ @subscriber_db =] '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.

Security Note:
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.

Security Note:
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.

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.

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

Note

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.
