How to remove records from the Live System

Introduction

The Delft-FEWS live system consists of the Master-Controllers, Forecasting Shell Servers and Operating Clients. In rare cases there are errors that make it is necessary to remove some records from the live system. The following steps will reduce the chance that these records are synchronised back to the central database system. Note that for several different removals of records from the central database are made available within the MCRecoveryTool.

2. Delete the records from the central database.

Removal of records with multiple Master-Controllers

1. Suspend all MC-MC Synchronisation tasks.
2. Remove all forecasting shell local datastores.
3. Remove the records from all central databases
4. Reactivate the MC-MC synchronisation tasks.
