Complete the attach phase for the fresh version by attaching the database to the server instance , which makes it available as a scalable shared database 通過將數(shù)據(jù)庫附加到服務(wù)器實(shí)例來完成新版本的附加階段,這將使此數(shù)據(jù)庫用作可縮放共享數(shù)據(jù)庫。
A scalable shared database enables you to scale - out a database using commodity hardware for reporting servers and volumes and to achieve a smooth upgrade path 通過可伸縮的共享數(shù)據(jù)庫,可以使用報(bào)表服務(wù)器和報(bào)表卷的標(biāo)準(zhǔn)硬件擴(kuò)展數(shù)據(jù)庫,以獲得平穩(wěn)的升級路徑。
We recommend that you limit your scalable shared database configurations to eight server instances per shared database . scalable shared databases do not support database snapshots 我們建議您將可縮放共享數(shù)據(jù)庫的配置限制為:每個(gè)共享數(shù)據(jù)庫接納8個(gè)服務(wù)器實(shí)例。
If only one set of reporting volumes is used for a scalable shared database configuration , the attach process during an update is equivalent to the original attach process 如果只有一組報(bào)表卷用于可縮放共享數(shù)據(jù)庫配置,則更新期間的附加過程等同于最初的附加過程。
Finally , the database is established as a scalable shared database during an attach phase that involves the same steps as used to attach a new reporting database 最后,在附加階段期間,數(shù)據(jù)庫建立為可縮放共享數(shù)據(jù)庫,此階段中涉及的步驟與用于附加新報(bào)表數(shù)據(jù)庫的步驟相同。
The following figure illustrates building a new reporting database using a single reporting volume and attaching the reporting database to make it available as a scalable shared database 下圖說明如何使用一個(gè)報(bào)表卷生成新的報(bào)表數(shù)據(jù)庫,以及如何將報(bào)表數(shù)據(jù)庫附加為可縮放共享數(shù)據(jù)庫。
The scalable shared database feature , which is new in microsoft sql server , allows you to scale out a read - only database built exclusively for reporting purposes a reporting database 可縮放共享數(shù)據(jù)庫功能是microsoft sql server中的新增功能,可用于擴(kuò)展專為報(bào)表用途生成的只讀數(shù)據(jù)庫( “報(bào)表數(shù)據(jù)庫
Perform the whole detach phase for the stale database by detaching it , which makes the scalable shared database unavailable on this reporting server , and dismounting the corresponding reporting volume or volumes 通過分離操作執(zhí)行舊數(shù)據(jù)庫的整個(gè)分離階段,這將使此報(bào)表服務(wù)器中的可縮放共享數(shù)據(jù)庫不可用,并卸除相應(yīng)的報(bào)表卷。
