如何:升級複寫指令碼 (複寫 Transact-SQL 程式設計)
Transact-SQL 指令碼檔案可以用於以程式設計的方式設定複寫拓撲。如需詳細資訊,請參閱<複寫系統預存程序概念>。如果您是 SQL Server 2005 中的 sysadmin 固定伺服器角色的成員,而且執行從 SQL Server 2000 建立的複寫指令碼,則指令碼可正確執行。如果您是 db_owner 固定資料庫角色或另一個角色的成員,則指令碼會失敗,發生錯誤 MSSQL_ENG021797 或 MSSQL_ENG021798,必須升級才行。
安全性注意事項 |
---|
雖然並不一定要升級由 sysadmin 角色的成員所執行的指令碼,但建議您依照本主題所述修改現有的指令碼。請根據主題<複寫代理程式安全性模型>的「代理程式所需的權限」一節所述,為每個複寫代理程式指定具有最小權限的帳戶。 |
這些安全性改進會影響現有指令碼中的下列預存程序,讓您可以明確地指定 Microsoft Windows 帳戶,並在這些帳戶下執行複寫代理程式工作,對權限可以有更多的控制:
sp_addpublication_snapshot:
現在當您執行 sp_addpublication_snapshot (Transact-SQL) 時,應該以 @job_login 和 @job_password 提供「Windows 認證」,以建立在「散發者」端執行「快照集代理程式」的作業。
sp_addpushsubscription_agent:
現在應該執行 sp_addpushsubscription_agent (Transact-SQL) 以明確地加入作業並提供「Windows 認證」(@job_login 和 @job_password),藉此在「散發者」端執行「散發代理程式」作業。在 SQL Server 2005 之前的SQL Server 版本中,這項作業會在建立發送訂閱時自動完成。
sp_addmergepushsubscription_agent:
現在應該執行 sp_addmergepushsubscription_agent (Transact-SQL) 以明確地加入作業並提供「Windows 認證」(@job_login 和 @job_password),藉此在「散發者」端執行「合併代理程式」作業。在 SQL Server 2005 之前的SQL Server 版本中,這項作業會在建立發送訂閱時自動完成。
sp_addpullsubscription_agent:
現在當您執行 sp_addpullsubscription_agent (Transact-SQL) 時,應該以 @job_login 和 @job_password 提供「Windows 認證」,以建立在「訂閱者」端執行「散發代理程式」的作業。
sp_addmergepullsubscription_agent:
現在當您執行 sp_addmergepullsubscription_agent (Transact-SQL) 時,應該以 @job_login 和 @job_password 提供「Windows 認證」,以建立在「訂閱者」端執行「合併代理程式」的作業。
sp_addlogreader_agent:
現在應該執行 sp_addlogreader_agent (Transact-SQL) 以手動加入作業並提供「Windows 認證」,藉此在「散發者」端執行「記錄讀取器代理程式」。在 SQL Server 2005 之前的SQL Server 版本中,這項作業會在建立交易式發行集時自動完成。
sp_addqreader_agent:
現在應該執行 sp_addqreader_agent (Transact-SQL) 以手動加入作業並提供「Windows 認證」,藉此在「散發者」端執行「佇列讀取器代理程式」。在 SQL Server 2005 之前的SQL Server 版本中,這項作業會在建立支援佇列更新的交易式發行集時自動完成。
在 SQL Server 2005 所導入的安全性模型中,複寫代理程式一定會使用 @job_name 和 @job_password 所提供的認證,與具有「Windows 驗證」的 SQL Server 執行個體建立連接。如需有關在執行複寫代理程式作業時所使用 Windows 帳戶之需求的資訊,請參閱<複寫代理程式安全性模型>。
安全性注意事項 |
---|
可能的話,會在執行階段提示使用者輸入安全性認證。如果將認證儲存在指令碼檔案中,請確定該檔案本身受到安全保護。 |
若要升級設定快照式或交易式發行集的指令碼
在現有的指令碼中,在發行集資料庫的「發行者」端先執行 sp_addlogreader_agent (Transact-SQL),再執行 sp_addpublication (Transact-SQL)。指定「Windows 認證」,「記錄讀取器代理程式」執行時會將該認證用於 @job_name 和 @job_password。如果代理程式會在與「發行者」時連接時使用「SQL Server 驗證」,則也必須指定 @publisher_security_mode 的值 0,以及 @publisher_login 和 @publisher_password 的 SQL Server 登入資訊。如此會建立發行集資料庫的「記錄讀取器代理程式」作業。
[!附註]
只有交易式發行集才需要這個步驟,快照式發行集不需要。
(選擇性) 在散發資料庫的「散發者」端先執行 sp_addqreader_agent (Transact-SQL),再執行 sp_addpublication (Transact-SQL)。指定「Windows 認證」,「佇列讀取器代理程式」執行時會將該認證用於 @job_name 和 @job_password。如此會為「散發者」建立「佇列讀取器代理程式」作業。
[!附註]
只有支援佇列更新訂閱者的交易式發行集才需要這個步驟。
(選擇性) 更新 sp_addpublication (Transact-SQL) 的執行,以針對實作新複寫功能的參數設定預設以外的值。
在發行集資料庫的「發行者」端先執行 sp_addpublication (Transact-SQL),再執行 sp_addpublication_snapshot (Transact-SQL)。指定 @publication 和「Windows 認證」,「快照集代理程式」執行時會將該認證用於 @job_name 和 @job_password。如果代理程式會在與「發行者」時連接時使用「SQL Server 驗證」,則也必須指定 @publisher_security_mode 的值 0,以及 @publisher_login 和 @publisher_password 的 SQL Server 登入資訊。這麼做會為發行集建立「快照集代理程式」作業。
(選擇性) 更新 sp_addarticle (Transact-SQL) 的執行,以針對實作新複寫功能的參數設定預設以外的值。
若要升級將訂閱加入至快照式或交易式發行集的指令碼
在執行建立訂閱的預存程序之後,請務必執行建立「散發代理程式」作業的預存程序,以同步處理訂閱。您使用的預存程序將依照訂閱類型而定。
如果是提取訂閱,則請更新 sp_addpullsubscription_agent (Transact-SQL) 的執行,以提供「Windows 認證」,在「訂閱者」端執行的「散發代理程式」會將該認證用於 @job_name 和 @job_password。此項作業會在執行 sp_addpullsubscription 之後完成。如需詳細資訊,請參閱<如何: 建立提取訂閱 (複寫 Transact-SQL 程式設計)>。
如果是發送訂閱,請在「發行者」端執行 sp_addpushsubscription_agent (Transact-SQL)。指定 @subscriber、@subscriber_db、@publication、「Windows 認證」等 (在「散發者」端執行的「散發代理程式」會將該認證用於 @job_name 和 @job_password),以及此代理程式作業的排程。如需詳細資訊,請參閱<如何:指定同步排程 (複寫 Transact-SQL 程式設計)>。此項作業會在執行 sp_addsubscription 之後完成。如需詳細資訊,請參閱<如何:建立發送訂閱 (複寫 Transact-SQL 程式設計)>。
若要升級設定合併式發行集的指令碼
(選擇性) 在現有的指令碼中,更新 sp_addmergepublication (Transact-SQL) 的執行,以針對實作新複寫功能的參數設定預設以外的值。
在發行集資料庫的「發行者」端先執行 sp_addmergepublication (Transact-SQL),再執行 sp_addpublication_snapshot (Transact-SQL)。指定 @publication 和「Windows 認證」,「快照集代理程式」執行時會將該認證用於 @job_name 和 @job_password。如果代理程式會在與「發行者」時連接時使用「SQL Server 驗證」,則也必須指定 @publisher_security_mode 的值 0,以及 @publisher_login 和 @publisher_password 的 SQL Server 登入資訊。這麼做會為發行集建立「快照集代理程式」作業。
(選擇性) 更新 sp_addmergearticle (Transact-SQL) 的執行,以針對實作新複寫功能的參數設定預設以外的值。
若要升級將訂閱加入至合併式發行集的指令碼
在執行建立訂閱的預存程序之後,請務必執行建立「合併代理程式」作業的預存程序,以同步處理訂閱。您使用的預存程序將依照訂閱類型而定。
如果是提取訂閱,則請更新 sp_addmergepullsubscription_agent (Transact-SQL) 的執行以提供「Windows 認證」,在「訂閱者」端執行的「合併代理程式」會將該認證用於 @job_name 和 @job_password。此項作業會在執行 sp_addmergepullsubscription 之後完成。如需詳細資訊,請參閱<如何: 建立提取訂閱 (複寫 Transact-SQL 程式設計)>。
