Setting up SQL Server Log Shipping between the primary mirror and the Log Shipping secondary database in Lync Server 2013
Topic Last Modified: 2013-02-21
Perform the following steps for log shipping to continue if the primary Persistent Chat database is failed over to its mirror database.
Manually fail over the primary Persistent Chat database to the mirror. This is done by using the Lync Server Management Shell and the Invoke-CsDatabaseFailover cmdlet. For details, see "Using Lync Server Management Shell Cmdlets" in Deploying SQL mirroring for Back End Server high availability in Lync Server 2013.
Using the SQL Server Management Studio, connect to the primary Persistent Chat Server mirror instance.
Be sure that the SQL Server Agent is running.
Right-click the mgc database, and then click Properties.
Under Select a page, click Transaction Log Shipping.
Select the Enable this as a primary database in a log shipping configuration check box.
Under Transaction log backups, click Backup Settings.
In the Network path to the backup folder box, type the network path to the share you created for the transaction log backup folder.
If the backup folder is located on the primary server, type the local path to the backup folder in the If the backup folder is located on the primary server, type a local path to the folder box. (If the backup folder is not on the primary server, you can leave this box empty.)
Important
If the SQL Server service account on your primary server runs under the local system account, you must create your backup folder on the primary server and specify a local path to that folder.
Configure the Delete files older than and Alert if no backup occurs within parameters.
Look at the backup schedule listed in the Schedule box under Backup job. To customize the schedule for your installation, click Schedule, and adjust the SQL Server Agent schedule, as required.
Important
Use the same settings that you used for the primary database.
Under Compression, select Use the default server setting, and click OK.
Under Secondary server instances and databases, click Add.
Click Connect, and connect to the instance of SQL Server that you have configured as your secondary server.
In the Secondary Database box, select the mgc database from the list.
On the Initialize Secondary database tab, select the option No, the secondary database is initialized.
On the Copy Files tab, in Destination folder for copied files, type the path of the folder into which the transaction logs backups should be copied, and click OK. This folder is often located on the secondary server.
Open the Script Configuration drop-down list, and select Script Configuration to New Query Window.
In the new query window, in Database Properties, click OK to begin the configuration process.
Select and run the first half of the query (see step 18) up to the line: -- ****** End: Script to be run at Primary: ******.
Important
Manually running this script is necessary because SQL Server Management Studio does not support multiple primary databases in a SQL Server Log Shipping configuration.
Select Cancel to close the Log File shipping configuration panel and to establish a working setup that correctly implements the log file shipping for both the primary and mirrored database (in case of failover).
Manually fail back the primary Persistent Chat database to the primary. This is done by using the Lync Server Management Shell, and the Invoke-CsDatabaseFailover cmdlet.
