In order for the master controller (and Forecasting Shell Server) to run properly several maintenance workflows must be scheduled. These workflows make sure the database does not overflow (they run the rolling barrel) and that configuration marked to be removed using the Configuration Manager actually gets deleted. In addition, each FSS must also run a rolling barrel task, usually once a day. This task runs the rolling barrel on the FSS and deletes configuration marked for deletion. Also the cache files are compacted which is essential for performance and preventing OutOfMemory errors. Both for synchronisation as for direct database access this maintenance of the cache files is important for optimal performance.
- MC_MarkedRecordManager - Removes records marked for deletion. This removes static entries only.
- MC_Synchronisation - Synchronise between several master controllers, only needed on duty standby systems
- MC_RollingBarrel - Removes expired records from the MC database (e.g. timeseries, model states etc)
- MC_SystemAlerter - Optional, used for triggering emails on log event codes.
- RollingBarrel_FSS (one for each FSS), recommended up to 2014.01 - synchronises the localDatastore and removes expired records from the FSS database. RollingBarrelFSS won't work unless module descriptors file is available and properly configured. Please use Compact_FSSCache.xml instead from 2014.02 onwards.
- Compact_FSSCache.xml, preferred worfklow replacing RollingBarrel_FSS since 2014.02 .
