Example Analysis of Skype for Business Conference failure

This article mainly introduces the Skype for Business conference failure example analysis, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

Lync/Skype for Business client creates a meeting error, prompting an error connecting to the server, so serious that the "meet now" option disappears.

Check the event log of the Skype4B frontend server and there are a large number of error alarms indicating the failure of the connection to the backend database and the full rtcxds log of the database.

There are clear fault errors, focus on troubleshooting SQL back-end database, here to mention: many deployment of Lync/Skype4B do not take into account the back-end SQL database management and maintenance, resulting in a system cascading failure.

By looking at the backend database, it is found that the log file of the rtcxds database is about 13g, and the storage disk space of the database is seriously insufficient. Here are the basic ways to shrink the database:

1. Back up the database (full backup and transaction log backup. The database recovery model is "complete" by default)

You can query the database log status first, and find that it is LOG_BACKUP.

Select log_reuse_wait_desc from sys.databases where name='rtcxds'

2. Back up log files

Backup log rtcxds to disk='D:\ dbbackup\ rtcxds-2017-01-06-1.log'

3. Shrink log files

DBCC SHRINKFILE (Numberrtcxdsdedicated Log', 100,100,100, TRUNCATEONLY)

After shrinking the database log file, the Skype4B conferencing failure was eliminated.

Finally, create a database maintenance plan, fully back up the database, back up the transaction log, shrink the database, and so on.
