function Set-DbaAgReplica { <# .SYNOPSIS Sets the properties for a replica to an availability group on a SQL Server instance. .DESCRIPTION Sets the properties for a replica to an availability group on a SQL Server instance. Automatically creates a database mirroring endpoint if required. .PARAMETER SqlInstance The target SQL Server instance or instances. Server version must be SQL Server version 2012 or higher. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential). Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported. For MFA support, please use Connect-DbaInstance. .PARAMETER Replica The replicas to modify. .PARAMETER AvailabilityGroup The availability group of the replica. .PARAMETER AvailabilityMode Sets the availability mode of the availability group replica. Options are: AsynchronousCommit and SynchronousCommit. SynchronousCommit is default. .PARAMETER FailoverMode Sets the failover mode of the availability group replica. Options are Automatic and Manual. .PARAMETER BackupPriority Sets the backup priority availability group replica. Default is 50. .PARAMETER EndpointUrl The endpoint URL. .PARAMETER InputObject Enables piping from Get-DbaAgReplica. .PARAMETER ConnectionModeInPrimaryRole Sets the connection intent modes of an Availability Replica in primary role. .PARAMETER ConnectionModeInSecondaryRole Sets the connection modes of an Availability Replica in secondary role. .PARAMETER ReadonlyRoutingConnectionUrl Sets the read only routing connection url for the availability replica. .PARAMETER SeedingMode Specifies how the secondary replica will be initially seeded. Automatic enables direct seeding. This method will seed the secondary replica over the network. This method does not require you to backup and restore a copy of the primary database on the replica. Manual requires you to create a backup of the database on the primary replica and manually restore that backup on the secondary replica. .PARAMETER SessionTimeout How many seconds an availability replica waits for a ping response from a connected replica before considering the connection to have failed. .PARAMETER WhatIf Shows what would happen if the command were to run. No actions are actually performed. .PARAMETER Confirm Prompts you for confirmation before executing any changing operations within the command. .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Tags: AvailabilityGroup, HA, AG Author: Chrissy LeMaire (@cl), netnerds.net Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Set-DbaAgReplica .EXAMPLE PS C:\> Set-DbaAgReplica -SqlInstance sql2016 -Replica sql2016 -AvailabilityGroup SharePoint -BackupPriority 5000 Sets the backup priority to 5000 for the sql2016 replica for the SharePoint availability group on sql2016 .EXAMPLE PS C:\> Get-DbaAgReplica -SqlInstance sql2016 | Out-GridView -Passthru | Set-DbaAgReplica -BackupPriority 5000 Sets the backup priority to 5000 for the selected availability groups. #> [CmdletBinding(SupportsShouldProcess, ConfirmImpact = 'Medium')] param ( [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [string]$AvailabilityGroup, [string]$Replica, [ValidateSet('AsynchronousCommit', 'SynchronousCommit')] [string]$AvailabilityMode, [ValidateSet('Automatic', 'Manual', 'External')] [string]$FailoverMode, [int]$BackupPriority, [ValidateSet('AllowAllConnections', 'AllowReadWriteConnections')] [string]$ConnectionModeInPrimaryRole, [ValidateSet('AllowAllConnections', 'AllowNoConnections', 'AllowReadIntentConnectionsOnly', 'No', 'Read-intent only', 'Yes')] [string]$ConnectionModeInSecondaryRole, [ValidateSet('Automatic', 'Manual')] [string]$SeedingMode, [int]$SessionTimeout, [string]$EndpointUrl, [string]$ReadonlyRoutingConnectionUrl, [parameter(ValueFromPipeline)] [Microsoft.SqlServer.Management.Smo.AvailabilityReplica]$InputObject, [switch]$EnableException ) process { if (-not $InputObject) { if (-not $AvailabilityGroup -or -not $Replica) { Stop-Function -Message "You must specify an AvailabilityGroup and replica or pipe in an availabilty group to continue." return } } if ($ConnectionModeInSecondaryRole) { $ConnectionModeInSecondaryRole = switch ($ConnectionModeInSecondaryRole) { "No" { "AllowNoConnections" } "Read-intent only" { "AllowReadIntentConnectionsOnly" } "Yes" { "AllowAllConnections" } default { $ConnectionModeInSecondaryRole } } } if ($SqlInstance) { $InputObject += Get-DbaAgReplica -SqlInstance $SqlInstance -SqlCredential $SqlCredential -AvailabilityGroup $AvailabilityGroup -Replica $Replica } foreach ($agreplica in $InputObject) { $server = $agreplica.Parent.Parent if ($Pscmdlet.ShouldProcess($server.Name, "Modifying replica for $($agreplica.Name) named $Name")) { try { if ($EndpointUrl) { $agreplica.EndpointUrl = $EndpointUrl } if ($FailoverMode) { $agreplica.FailoverMode = [Microsoft.SqlServer.Management.Smo.AvailabilityReplicaFailoverMode]::$FailoverMode } if ($AvailabilityMode) { $agreplica.AvailabilityMode = [Microsoft.SqlServer.Management.Smo.AvailabilityReplicaAvailabilityMode]::$AvailabilityMode } if ($ConnectionModeInPrimaryRole) { $agreplica.ConnectionModeInPrimaryRole = [Microsoft.SqlServer.Management.Smo.AvailabilityReplicaConnectionModeInPrimaryRole]::$ConnectionModeInPrimaryRole } if ($ConnectionModeInSecondaryRole) { $agreplica.ConnectionModeInSecondaryRole = [Microsoft.SqlServer.Management.Smo.AvailabilityReplicaConnectionModeInSecondaryRole]::$ConnectionModeInSecondaryRole } if ($BackupPriority) { $agreplica.BackupPriority = $BackupPriority } if ($ReadonlyRoutingConnectionUrl) { $agreplica.ReadonlyRoutingConnectionUrl = $ReadonlyRoutingConnectionUrl } if ($SeedingMode) { $agreplica.SeedingMode = $SeedingMode } if ($SessionTimeout) { if ($SessionTimeout -lt 10) { $Message = "We recommend that you keep the time-out period at 10 seconds or greater.
