如何升级复制脚本(复制 Transact-SQL 编程)
Transact-SQL 脚本文件可用于以编程方式配置复制拓扑。有关详细信息,请参阅复制系统存储过程概念。如果您是 SQL Server 2005 中 sysadmin 固定服务器角色的成员,并且运行从 SQL Server 2000 创建的复制脚本,则这些脚本将正确执行。如果您是 db_owner 固定数据库角色或其他角色的成员,这些脚本将因出现 MSSQL_ENG021797 或 MSSQL_ENG021798 错误而失败且必须升级。
安全说明 |
---|
虽然不需要升级由 sysadmin 角色的成员执行的脚本,我们仍建议您按照本主题中的说明修改现有脚本。按照复制代理安全性模式主题的“代理所需权限”部分的说明为每个复制代理指定一个具有最低权限的帐户。 |
这些安全改进允许您显式指定用于执行复制代理作业的 Microsoft Windows 帐户,从而可对权限进行更多控制,这些安全改进会影响现有脚本中的以下存储过程:
sp_addpublication_snapshot:
现在,在分发服务器上执行 sp_addpublication_snapshot (Transact-SQL) 来创建该作业时,应提供 Windows 凭据作为快照代理运行时使用的 @job_login 和 @job_password。
sp_addpushsubscription_agent:
现在应执行 sp_addpushsubscription_agent (Transact-SQL) 以显式添加作业,并提供在分发服务器上运行分发代理作业所使用的 Windows 凭据(@job_login 和 @job_password)。在 SQL Server 2005 之前的 SQL Server 版本中,当创建推送订阅时会自动执行此操作。
sp_addmergepushsubscription_agent:
现在应执行 sp_addmergepushsubscription_agent (Transact-SQL) 以显式添加作业,并提供在分发服务器上运行合并代理作业所使用的 Windows 凭据(@job_login 和 @job_password)。在 SQL Server 2005 之前的 SQL Server 版本中,当创建推送订阅时会自动执行此操作。
sp_addpullsubscription_agent:
现在,在订阅服务器上执行 sp_addpullsubscription_agent (Transact-SQL) 来创建该作业时,应提供 Windows 凭据作为分发代理运行时使用的 @job_login 和 @job_password。
sp_addmergepullsubscription_agent:
现在,在订阅服务器上执行 sp_addmergepullsubscription_agent (Transact-SQL) 来创建该作业时,应提供 Windows 凭据作为合并代理运行时使用的 @job_login 和 @job_password。
sp_addlogreader_agent:
现在应执行 sp_addlogreader_agent (Transact-SQL) 以手动添加作业,并提供在分发服务器上用于运行日志读取器代理的 Windows 凭据。在 SQL Server 2005 之前的 SQL Server 版本中,当创建事务发布时会自动执行此操作。
sp_addqreader_agent:
现在应执行 sp_addqreader_agent (Transact-SQL) 以手动添加作业,并提供在分发服务器上运行队列读取器代理所使用的 Windows 凭据。在 SQL Server 2005 之前的 SQL Server 版本中,当创建支持排队更新的事务发布时会自动执行此操作。
在 SQL Server 2005 引入的安全模式中,复制代理总是使用 @job_name 和 @job_password 中提供的凭据连接到带有 Windows 身份验证的 SQL Server 本地实例。有关运行复制代理作业时所使用的 Windows 帐户的要求,请参阅复制代理安全性模式。
安全说明 |
---|
如果可能,请在运行时提示用户输入安全凭据。如果将凭据保存在脚本文件中,请确保该文件本身受到安全保护。 |
升级用于配置快照发布或事务发布的脚本
在现有脚本中,在执行 sp_addpublication (Transact-SQL) 之前,在发布服务器上对发布数据库执行 sp_addlogreader_agent (Transact-SQL)。为 @job_name 和 @job_password 指定用于运行日志读取器代理的 Windows 凭据。如果代理在连接到发布服务器时将使用 SQL Server 身份验证,则还必须将 @publisher_security_mode 的值指定为 0,并为 @publisher_login 和 @publisher_password 指定 SQL Server 登录信息。这样,便为发布数据库创建了一个日志读取器代理作业。
注意 此步骤仅针对事务发布,无需对快照发布执行该步骤。
(可选)在执行 sp_addpublication (Transact-SQL) 之前,在分发服务器上对分发数据库执行 sp_addqreader_agent (Transact-SQL)。为 @job_name 和 @job_password 指定用于运行队列读取器代理的 Windows 凭据。这样,便为分发服务器创建了一个队列读取器代理作业。
注意 仅需要对支持排队更新订阅服务器的事务发布执行此步骤。
(可选)更新 sp_addpublication (Transact-SQL) 的执行以对用于实现新复制功能的参数设置任何非默认的值。
在执行 sp_addpublication (Transact-SQL) 之后,在发布服务器上对发布数据库执行 sp_addpublication_snapshot (Transact-SQL)。指定 @publication,并为 @job_name 和 @job_password 指定用于运行快照代理的 Windows 凭据。如果代理在连接到发布服务器时将使用 SQL Server 身份验证,则还必须将 @publisher_security_mode 的值指定为 0,并为 @publisher_login 和 @publisher_password 指定 SQL Server 登录信息。这将会为发布创建快照代理作业。
(可选)更新 sp_addarticle (Transact-SQL) 的执行以对用于实现新复制功能的参数设置任何非默认的值。
升级向快照发布或事务发布添加订阅的脚本
在执行用于创建订阅的存储过程之后,请确保执行用于创建分发代理作业的存储过程以同步订阅。所用的存储过程将取决于订阅类型。
对于请求订阅,更新 sp_addpullsubscription_agent (Transact-SQL) 的执行从而为 @job_name 和 @job_password 提供在订阅服务器上运行分发代理所使用的 Windows 凭据。此操作将在执行 sp_addpullsubscription 后完成。有关详细信息,请参阅如何创建请求订阅(复制 Transact-SQL 编程)。
对于推送订阅,在发布服务器上执行 sp_addpushsubscription_agent (Transact-SQL)。指定 @subscriber、@subscriber_db、@publication,并为 @job_name 和 @job_password 指定在分发服务器上运行分发代理所使用的 Windows 凭据,同时指定此代理作业的计划。有关详细信息,请参阅如何指定同步计划(复制 Transact-SQL 编程)。此操作将在执行 sp_addsubscription 后完成。有关详细信息,请参阅如何创建推送订阅(复制 Transact-SQL 编程)。
升级用于配置合并发布的脚本
(可选)在现有脚本中,更新 sp_addmergepublication (Transact-SQL) 的执行以对用于实现新复制功能的参数设置任何非默认的值。
在执行 sp_addmergepublication (Transact-SQL) 之后,在发布服务器上对发布数据库执行 sp_addpublication_snapshot (Transact-SQL)。指定 @publication,并为 @job_name 和 @job_password 指定用于运行快照代理的 Windows 凭据。如果代理在连接到发布服务器时将使用 SQL Server 身份验证,则还必须将 @publisher_security_mode 的值指定为 0,并为 @publisher_login 和 @publisher_password 指定 SQL Server 登录信息。这将会为发布创建快照代理作业。
(可选)更新 sp_addmergearticle (Transact-SQL) 的执行以对用于实现新复制功能的参数设置任何非默认的值。
升级向合并发布添加订阅的脚本
执行完用于创建订阅的存储过程后,请确保执行用于创建合并代理作业的存储过程以同步订阅。所用的存储过程将取决于订阅类型。
对于请求订阅,更新 sp_addmergepullsubscription_agent (Transact-SQL) 的执行从而为 @job_name 和 @job_password 提供在订阅服务器上运行合并代理所使用的 Windows 凭据。此操作将在执行 sp_addmergepullsubscription 后完成。有关详细信息,请参阅如何创建请求订阅(复制 Transact-SQL 编程)。
对于推送订阅,在发布服务器上执行 sp_addmergepushsubscription_agent (Transact-SQL)。指定 @subscriber、@subscriber_db、@publication,并为 @job_name 和 @job_password 指定在分发服务器上运行合并代理所使用的 Windows 凭据,同时指定此代理作业的计划。有关详细信息,请参阅如何指定同步计划(复制 Transact-SQL 编程)。此操作将在执行 sp_addmergesubscription 后完成。有关详细信息,请参阅如何创建推送订阅(复制 Transact-SQL 编程)。
