Uninstall-CsMirrorDatabase

Uninstalls a Skype for Business Server mirror database. A database mirror enables you to simultaneously maintain two copies of a database, each copy residing on a different server. This cmdlet was introduced in Lync Server 2013.

Syntax

Uninstall-CsMirrorDatabase
         -DatabaseType <DatabaseNameType>
         -SqlServerFqdn <Fqdn>
         [-Confirm]
         [-DropExistingDatabasesOnMirror]
         [-Report <String>]
         [-SqlInstanceName <String>]
         [-WhatIf]
         [<CommonParameters>]

Description

Mirror databases enable you to simultaneously maintain two copies of a database: when data is written to Database A, a copy of that data is also written to its mirror database. This provides the ability to instantly replace Database A should that database become unavailable: you can "failover" to the mirror database with minimal disruption to your users and with minimal data loss.

Mirror databases can be installed and configured by using the Install-CsMirrorDatabase cmdlet. If you ever need to remove a mirror database, you can do so by using the Uninstall-CsMirrorDatabase cmdlet.

Skype for Business Server Control Panel: The functions carried out by the Uninstall-CsMirrorDatabase cmdlet are not available in the Skype for Business Server Control Panel.

Examples

-------------------------- Example 1 --------------------------

Uninstall-CsMirrorDatabase -SqlServerFqdn "atl-mirror-001.litwareinc.com" -SqlInstanceName "RTC" -DatabaseType "User" -DropExistingDatabasesOnMirror

The command shown in Example 1 uninstalls the user database from the SQL Server instance RTC on the computer atl-mirror-001.litwareinc.com. Because the DropExistingDatabaseOnMirror parameter was included, the command will also delete the actual User database mirror.
