Server States
The operating system and the services of a FOXMAN-UN server can be in different states. In the FOXMAN-UN context these states will be mapped to so called Server States depending on whether a FOXMAN-UN server is of type Standard, Main or Standby. The possible Server States are listed in the following table:
FOXMAN-UN Services State | State of Standard Server | State of Main Server | State of Standby Server | Remark |
|---|---|---|---|---|
Operating System (Linux) not running | No Connection | No Connection | No Connection | |
Operating System (Linux) restarting | No Connection | No Connection | No Connection | In case of a Main or a Standby Server, restarting the OS will result in started up Base Services and not started up Cores Services. In case of a Standard Server, restarting the OS will result in started up Base and Core Services. |
Base Services not running | No Connection | No Connection | No Connection | |
Base Services restarting | No Connection | No Connection | No Connection | Restarting the base services will also restart the core services (if they are running). |
Base Services running and Core Services not running | Not Running | Not Running | Standby | |
Core Services stopping | Stopping | Stopping | Stopping | |
Core Services starting | Starting | Starting | Starting | |
Core Services restarting | Restarting | Restarting | Restarting | |
Base and Core Services running | Running | Running | Running | Core Services can only be running if also base services are running. |
