Parallel servers¶

Parallel servers are used to increase the performance and availability of server systems. Exactly two versiondog servers are combined to form a network.

Requirements¶

• The two servers must be installed on different computers.
• The two servers must each have their own parallel server license (i.e. the serial numbers must be different).

Advantages of parallel servers¶

• Fail-safe
  • Both servers have the same data. As soon as the data changes, the servers are synchronized.
  • The versiondog applications are kept redundant. If one server fails, the remaining server alone takes over all tasks.
• Load balancing
  • The resulting loads, in particular Check-In/Check-Out processes and scheduler jobs, are automatically distributed between the two servers by default.
  • Clients can optionally login to a specific server. If this is not available, the other server is automatically selected.
  • Scheduler jobs can be explicitly assigned to a specific server. If this server is unavailable, the other server automatically takes over the jobs.
