The ObjectUseCountCollectRate field in DBS Control controls when the system writes the counts to the Data Dictionary. The field sets the number of minutes you want the system to wait before it writes the cached counts to the Data Dictionary table DBC.ObjectUsage. The recommended minimum value is 10 minutes. The default value is also 10 minutes. Any rate below 10 minutes may impact performance of systems with heavy workloads. The counts also write to disk when the cache is full. You can also write the counts to DBC.ObjectUsage whenever applications require it by using a FLUSH QUERY LOGGING WITH USECOUNT request.
