在這個可用性群組中,至少有一個次要複本具有 NOT SYNCHRONIZING 同步處理狀態,而且並未收到來自主要複本的資料。 可能的解決方案 使用可用性複本原則狀態來尋找具有 NOT SYNCHRONIZING 狀態的可用性複本,然後解決可用性複本的問題。 另請參閱 AlwaysOn 可用性群組概觀 (SQL Server) 使...
例如,假設 SQL Server 正在執行,且可用性資料庫設定為Recovery Pending或Suspect狀態。 當您使用下列 SQL 腳本查詢主要複本上的動態管理檢視 (DMV)時,資料庫可能會回報NOT_HEALTHY為 和RECOVERY_PENDING狀態或SUSPECT狀態,如下所示: SQL SELECTdc.database_name, d.synchronizati...
例如,假设 SQL Server 正在运行,可用性数据库设置为Recovery Pending或Suspect状态。 使用以下 SQL 脚本查询主要副本的动态管理视图(DMV)时,数据库可能以状态RECOVERY_PENDING或SUSPECT状态报告NOT_HEALTHY,如下所示: SQL SELECTdc.database_name, d.synchronization_health_desc, d.synchronization_state_desc, d.databa...

Starting with SQL Server 2016 (13.x), fast inserts are enabled by default, using minimal logging when database is in simple or bulk logged recovery model to optimize insert performance for records inserted into new pages. With fast inserts, each bulk load batch acquires new extents bypassing ...
RESTORE WITH MOVE:若要建立次要資料庫,在裝載次要複本的每個 SQL Server 執行個體上,資料庫檔案必須是 RESTORED WITH MOVE。 對新增檔案作業的影響:在次要資料庫上,對主要複本稍後的新增檔案作業可能會失敗。 此失敗可能導致次要資料庫暫停。 而這又會導致次要複本進入 NOT SYNCHRONIZING 狀態。
1、primary_recovery_health_desc , secondary_recovery_health_desc 主要展示相关的服务是否在线 2、synchronization_health_desc 当前同步的状态 3、recovery_health_desc 判断当前同步组中的所有数据库是否都在同步中,如果展示为 ONLINE_IN_PROGRESS, 则说明在复制组中的某个数据库不在同步状态, 如果展示为 PROGRESS...
The databases indicate the "Not Synchronizing" status. You review the sys.dm_exec_requests DMV and notice the DB STARTUP command is blocked on wait HADR_RECOVERY_WAIT_FOR_UNDO.In this scenario, you restart the SQL Server instance hosting the primary replica of the availability group. Then the...
When you perform an in-place upgrade of a secondary replica to a newer version of SQL Server, the database inside the availability group remains in theSynchronizing / In recoveryorSynchronized / In Recoverystate until the availability group is manually failed over, which finishes the recovery and...
Additionally, the availability databases report that they are in a NOT SYNCHRONIZING state, and applications can't access these databases.For example, in the following image, SQL Server Management Studio reports that the secondary replica is in a RESOLVING state because the automa...
