Xds: xds on Lync frontend server maintain a read only copy of xds database which is part of central management store and resides in SQL backend database server. Therefore, Lync 2013 maintains presence information on Lync Front End Servers.īelow is the list of frontend server databases:
Microsoft lync 2013 datasheet update#
In lync 2013 Front End & Back End are loosely coupled and use lazy writes to update the databases. There are three databases (xds, rtc & rtcdyn) under RTC Local which created at the time of Lync Installation on each Front End server and maintain the replica from Lync Bank End Server. Lync Front End Server Local databases: Lync FE server uses SQL express edition to store databases under database instance name RTC Local. Rgsdyn: rgsconfig maintains the runtime data for response group configuration service data file. Rgsconfig: rgsconfig maintains the response group configuration service data file.

Rtcab: rtcab stands for real time communication address book and maintain the address book service informationĬpsdyn: cpsdyn maintains the dynamic information database for Call Park application. Rtcshared: rtcshared hosts the conferencing directory Rtcxds: rtcxds maintains the backup for user data Lis: lis stand for Location information service and maintains the location information service data. and replicate a read only copy to every subsequent lync server. Xds: xds is the main database of Lync Server and part of central management store which maintain the topology information, polices, configuration etc. SQL Back End server store Central Management Store, users & applications databases for Lync Enterprise Edition FE pool.īelow is the list of backend server databases:

For more information about the collocation of database please go through You can also use the same database server for archiving, monitoring, persistent chat and persistent chat compliance databases. Lync Back End Server databases: Lync Back End (SQL) Server maintains Lync Central Management Store, users & applications databases. So, now we will have a look into the databases and their uses. You can configure SQL mirror to achieve High Availability for Lync Back End, Archiving, Monitoring, and Persistent Chat and Persistent Chat Compliance databases. Lync Server 2013 use SQL Server 2012 Express Edition (64 bit) for servers where Lync server role require local configuration database and SQL Server 2008 R2/2012 (64 bit) for Lync Back End, Archiving, Monitoring, and Persistent Chat and Persistent Chat Compliance databases.
