System structure of octoplant¶
There are various possible scenarios for how a octoplant system can be set up and operated. However, the basic structure of a server is always the same and consists of a Windows service and the associated processes that are monitored by this service.
The VDog MasterService monitors all subordinate server processes. In the event of any problems, these are reported to the administrators by email. At the same time, the VDog MasterService attempts to rectify the problems directly. Automatic rectification only fails in exceptional cases. Intervention by an administrator is only necessary in the rarest of cases.
In general, this is a very stable process structure. Even if all server processes were to fail, access to the user data is still possible.
FAQ¶
How to restart the octoplant system after a server failure
To restart octoplant after a server failure without losses, stop the VDog MasterService using the Service Control Manager if possible before restarting the server operating system. After all relevant processes have been terminated, restart the server operating system.
Warning
Restarting the operating system can put the PostgreSQL database in a corrupt state.
