SharePoint 2013 - Large SharePoint_Config Database

Question

I have what appears to be a large SharePoint_config database:

SharePoint_Config.mdf = 99GB 
SharePoint_Config_Log.ldf = 14GB

Is this normal? How can I decrease the size of this database?

Answer 1

This is not normal, config DB should be couple of gigs. If some cleanup jobs stop working then we can see the increase the size of config DB.

• check which table is larger in size. using table by size report.

We had problem in past, where "timer job history cleanup" timer job stop working and due to that no more purging in history tables and in a couple of months we were around 150GB,
