说明
The Test-SqlDatabaseReplicaState cmdlet assesses the health of an availability database on all joined availability replicas by evaluating SQL Server policy based management (PBM) policies. You must have CONNECT, VIEW SERVER STATE, and VIEW ANY DEFINITION permissions to execute this cmdlet.
示例
Example 1: Evaluate the health of an availability database
PS C:\> $Path = "SQLSERVER:\Sql\Computer\Instance\AvailabilityGroups\MainAg\DatabaseReplicaStates\MainReplica.MainDatabase"
PS C:\> Test-SqlDatabaseReplicaState -Path $Path
This command evaluates the health of the availability database named MainDatabase on the availability replica MainReplica in the availability group MainAg and outputs a brief summary.
Example 2: Evaluate the health of all availability databases in an availability group
PS C:\> Get-ChildItem "SQLSERVER:\Sql\Computer\Instance\AvailabilityGroups\MainAg\DatabaseReplicaStates" | Test-SqlDatabaseReplicaState
This command evaluates the health of all availability databases in the MainAg availability group and outputs a brief summary for each database.
Example 3: Evaluate the health of all availability databases in an availability group showing PBM evaluation results
PS C:\> Get-ChildItem "SQLSERVER:\Sql\Computer\Instance\AvailabilityGroups\MainAg\DatabaseReplicaStates" | Test-SqlDatabaseReplicaState -ShowPolicyDetails
This command evaluates the health of all availability databases in the MainAg availability group and outputs the evaluation results for each PBM policy that was executed.
Example 4: Evaluate the health of all availability databases in an availability group and include user-defined policies
PS C:\> Get-ChildItem "SQLSERVER:\Sql\Computer\Instance\AvailabilityGroups\MainAg\DatabaseReplicaStates" | Test-SqlDatabaseReplicaState -AllowUserPolicies
This command evaluates the health of all availability databases in the MainAg availability group. User-defined policies are included in this evaluation.
Example 5: Show all availability databases in an error health state
PS C:\> Get-ChildItem "SQLSERVER:\Sql\Computer\Instance\AvailabilityGroups\MainAg\DatabaseReplicaStates" | Test-SqlDatabaseReplicaState | Where-Object { $_.HealthState -eq "Error" }
This command shows all availability databases with a health state of "Error" in the MainAg availability group.
