Synchronizing parallel servers¶
Parallel servers can only be synchronized if they are linked to each other.
Parallel servers are synchronized automatically. Manual synchronization is only carried out when an individual server is converted to a parallel server. Manual synchronization can be carried out via the application VDogParallelServerUtil.exe.
Warning
When you run the VDogParallelServerUtil.exe on server A (connected to server B), this tool will cause server B to be overwritten. It will delete the server archive and remote share (if present) from server B. The data is not restorable in the event of errors or non-completion. Please make a backup of your data!
Parallel servers are automatically synchronized if changes are detected in the following data/objects.
- Job results of the scheduler
- Global settings
- Job configuration
- Components
- Component types
- Scripts
- User management
- Agents
- User data
- Upload classes
- Compare classes
Synchronization takes place directly in normal operation. A delay may occur if there is a very heavy server load (e.g. many large Check-In/Check-Out processes at the same time, many scheduler jobs running in parallel).
Info
If the synchronization fails, there is no rollback on the server that has already been changed.
FAQ¶
Last checked-in version of the component was overwritten on a server in parallel server mode
If the connection between the two servers fails unnoticed for a period of time in parallel server mode, different versions of the component may have been checked in on the two servers. If the connection is restored, the serial number is checked. The last checked-in version on the server with the smaller serial number is retained and copied to the other server. The version on the server with the larger serial number is overwritten and is no longer available.
