Set-MailboxDatabaseCopy

 

Applies to: Exchange Server 2013

Topic Last Modified: 2012-08-03

Use the Set-MailboxDatabaseCopy cmdlet to configure the properties of a database copy.

For information about the parameter sets in the Syntax section below, see Syntax.

Set-MailboxDatabaseCopy -ClearHostServer <SwitchParameter> -Identity <DatabaseCopyIdParameter> <COMMON PARAMETERS>
Set-MailboxDatabaseCopy -Identity <DatabaseCopyIdParameter> [-ActivationPreference <UInt32>] <COMMON PARAMETERS>
COMMON PARAMETERS: [-Confirm [<SwitchParameter>]] [-DatabaseCopyAutoActivationPolicy <Unrestricted | IntrasiteOnly | Blocked>] [-DomainController <Fqdn>] [-ReplayLagTime <EnhancedTimeSpan>] [-TruncationLagTime <EnhancedTimeSpan>] [-WhatIf [<SwitchParameter>]]

This example configures the replay lag time with a value of 3 days for a copy of the database DB2 hosted on the Mailbox server MBX1.

Set-MailboxDatabaseCopy -Identity DB2\MBX1 -ReplayLagTime 3.0:0:0

This example configures an activation preference of 3 for the copy of the database DB1 hosted on the Mailbox server MBX2.

Set-MailboxDatabaseCopy -Identity DB1\MBX2 -ActivationPreference 3

With this cmdlet, you can configure the replay lag time, truncation lag time, and activation preference value for a mailbox database copy.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Database availability groups" entry in the High Availability and Site Resilience Permissions topic.

 

Parameter Required Type Description

ClearHostServer

Required

System.Management.Automation.SwitchParameter

This parameter is reserved for internal Microsoft use.

Identity

Required

Microsoft.Exchange.Configuration.Tasks.DatabaseCopyIdParameter

The Identity parameter specifies the name of the database whose copy is being modified.

ActivationPreference

Optional

System.UInt32

The ActivationPreference parameter value is used as part of Active Manager's best copy selection process and to redistribute active mailbox databases throughout the database availability group (DAG) when using the RedistributeActiveDatabases.ps1 script. The value for the ActivationPreference parameter is a number equal to or greater than 1, where 1 is at the top of the preference order. The position number can't be larger than the number of database copies of the mailbox database.

Confirm

Optional

System.Management.Automation.SwitchParameter

The Confirm switch causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm switch.

DatabaseCopyAutoActivationPolicy

Optional

Microsoft.Exchange.Data.Directory.SystemConfiguration.DatabaseCopyAutoActivationPolicyType

This parameter is reserved for internal Microsoft use.

DomainController

Optional

Microsoft.Exchange.Data.Fqdn

The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory.

ReplayLagTime

Optional

Microsoft.Exchange.Data.EnhancedTimeSpan

The ReplayLagTime parameter specifies the amount of time that the Microsoft Exchange Replication service should wait before replaying log files that have been copied to the passive database copy. Setting this parameter to a value greater than 0 creates a lagged database copy.

To specify a value, enter it as a time span: dd.hh:mm:ss where d = days, h = hours, m = minutes, and s = seconds.

The maximum allowable setting for this value is 14 days. The minimum allowable setting is 0 seconds, and setting this value to 0 seconds eliminates any delay in log replay activity.

For example, to specify a 14-day replay lag period, enter 14.00:00:00. The default value is 00.00:00:00, which specifies that there's no replay lag.

TruncationLagTime

Optional

Microsoft.Exchange.Data.EnhancedTimeSpan

The TruncationLagTime parameter specifies the amount of time that the Microsoft Exchange Replication service should wait before truncating log files that have replayed into the passive copy of the database. The time period begins after the log has been successfully replayed into the copy of the database.

To specify a value, enter it as a time span: dd.hh:mm:ss where d = days, h = hours, m = minutes, and s = seconds.

The maximum allowable setting for this value is 14 days. The minimum allowable setting is 0 seconds, and setting this value to 0 seconds eliminates any delay in log truncation activity.

For example, to specify a 14-day truncation lag period, enter 14.00:00:00. The default value is 00.00:00:00, which specifies that there's no truncation lag.

WhatIf

Optional

System.Management.Automation.SwitchParameter

The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf switch.
