While investigating a recent Lync issue, I had to reacquaint myself with the main databases used in a Lync deployment. In this blog post, I have documented my experiences for the benefit of others. The Types and Uses of Databases in Lync. Microsoft Lync Server 2. Microsoft SQL. The two flavors of the core Front End Lync Server role requires SQL Lync 2. Server Standard Edition ships with, installs, and uses Microsoft SQL Server 2. Express Edition 6. Lync 2. 01. 0 Server Enterprise Edition requires Microsoft SQL Server 2. SP1 or 2. 00. 5 SP3 6.

Application category Description Microsoft Office 2010 applications Download a list of all settings synced Microsoft Word 2010. Microsoft Excel 2010. Microsoft SQL Server 2. R2. The 3. 2 bit versions of SQL are not supported. You can read more about the supported Database Software prerequisites here Microsoft Lync 2. Database Software and Clustering Support. Lync Server 2. 01. SQL databases 1 Central Management Store CMSThe CMS store is used by the Central Management Service to maintain a current Lync Server 2. Topology for the entire Lync deployment Topology, Policies, Voice Routes, etc. Here is what you need to know about the CMS The database used for this purpose is called Xds it maintains the Lync configuration as published by the Topology Builder. There is only one master copy of CMS database which is automatically installed on the first instance of a Standard or Enterprise Edition Lync pool. For Enterprise Edition pools this first instance will reside on the SQL back end database for the pool. Every subsequent Lync server in the topology gets a read only copy of it. A topology change on the master is replicated to each read only copy on each Lync server. This is a key element to Lync Servers survivability feature set if the network connection between a Lync Edge server goes down for example, the Edge server still knows about the topology and can keep functioning. Changes are replicated to all Lync server roles except the Lync Edge using the Windows file copy SMB protocol on port 4. Changes are replicated to the Edge role via HTTPS on port 4. The Windows service Lync server replica replicator agent is responsible for receiving the snapshot and uploading the local copies of the databases. It then sends a status update to the Master Replicator also a windows service running on the CMS. Pool Configuration Store. How To Build An Installer Is Currently Running more. The pool back end database is the heart of Lync functionality. The Registrar, User Services, and the Address Book use this database for registration, routing, presence information conferences, replicating user information, in band provisioning, and address book functionality. This is commonly referred to the Lync back end database, and one exists for each Lync pool. The following 3 important databases are used for the core feature set of Lync Rtc stores persistent user data such as user contact lists, scheduled conferences, and access control lists. Rtcdyn stores dynamic Lync user data such as presence information. Rtcab Rtcab. Lync address book information i. AD.  The Lync Address Book server alternates use of these databases one of them is used to service address book queries while the other is being updated. Once the updates are done, they switch roles. Theses databases contain a table called Ab. Attribute which specifies which AD fields will be used in the Lync Address Book database and ultimately the Lync address book files. If you are having permission issues with either of these databases, see Access to the Lync Server Address Book Databases. Application Store. Lync server uses the following databases for the Call Park and Response Group applications Cpsdyn stores dynamic system information for the Call Park application. Rgsdyn stores dynamic runtime operational information for the Call Park application. Rgsconfig stores persistent configuration data for the Response Group application. Archiving and Monitoring Store. This store is used by the Lync Archiving Server Role and the Monitoring Server Role. There are 3 separate databases used Lcs. Log stores Instant Messaging and Conferencing data for archiving purposes used by the Archiving Role. Lcs. Cdr stores the Call Details Records used by the Monitoring RoleQo. EMetrics stores the Quality of Experience data used by the Monitoring Role5 Location Store. Lync server uses this database named lis to hold a network wiremap that maps network elements e. WAPs, routers to real civic addresses to provide the new Location and Emergency Services Support E9 1 1 features. All of the individual SQL databases used for each Lync purpose is listed here SQL Server Data and Log File Placement. RTC A Source of Confusion. A common source of confusion when trying to understand the Lync databases is the presence of multiple Lync SQL instances and databases which share the name RTC. Here is a breakdown An. SQL instance named RTC is used to store the back end pool databases, including the master CMS database. This is installed on the first Front End server or back end pool that was installed in the Lync Organization. RTC is the default name for this instance it can be changed or removed to use the base SQL instance. Another SQL instance named RTCLOCAL which is a SQL Express Instance present on each Lync Front End server which is used to hold a replica of the CMS database, and the databases necessary for registration and routing. The presence of an SQL database named rtc which holds the persistent configuration information for the pool such as user contact lists, scheduled conferences, etc. The diagram below illustrates these Lync SQL instances and databases in an example Lync organization with 2 pools and 3 front end servers. In this organization, the Standard Edition Pool and associated Front End server was the first to be installed in this organization. Remember, there is only one master copy of CMS database which is automatically installed on the first instance of a Standard Edition or Enterprise Edition Lync pool. This database is shown in red xds. The other xds databases shaded in gray are read only copies replicated to the other 2 Enterprise Edition Front End servers. Putting It All Together. Power. Shell. One the great features introduced with Lync server is Power. Shell access to almost everything in the Lync system. You can install, install, and configure the various Lync databases from Power. Shell. See Database and Management Server Cmdlets for a list of Lync Management Server cmdlets. One of the more useful cmdlets is the Get Cs. Configuration. Store. Location cmdlet. This cmdlet will tell you the location of the Active Directory Service Control Point SCP for the Central Management Store. This AD location allows Lync server to locate the Lync CMS SQL database server instance a crucial setting to the operation of Lync. Note the default AD location for the CMS SCP object is CNTopology Settings, CNRTC Service, DClt example. The ms. RTCSIP Back. End. Server attribute contains the SQL server and instance name of the master CMS copy. The back end pool database is crucial for Lync login and function. The back end for any pool can be viewed in the Lync Topology builder, or you can retrieve the SQL serverand instance name for any back end pool database using the following Power.
