Parallel server

Parallel servers serve to increase the performance and availability of server systems. To do this, two versiondog servers are networked.

Requirements:

• The two servers must be installed on different computers.
• The two servers must each have a separate parallel server license (that is to say, the serial numbers must be different).

Advantages of parallel servers:

• Guaranteed service availability
  • Both servers have the same data bases. As soon as the data is changed, the servers are synchronized.
  • versiondog applications are kept redundant. If one server goes down, the remaining server takes over all tasks.
• Load sharing
  • The resulting loads, especially Check-In and Check-Out operations and scheduled jobs are automatically distributed between the two servers by default.
  • Clients can optionally log on to a specific server. But if that server is not available, the client will automatically log on to the other one.
  • Scheduled jobs can be explicitly assigned to a particular server. If this server fails, the respective other server automatically takes over the jobs.

Windows-Eventlog, in the versiondog event log and, if configured, per e-mail. This warning is regenerated every 24 hours as long as the server is not available. As soon as the server has been restarted, the configured time period applies again. When the server becomes available again, the parallel server operation will be resumed.
