Redundancy helps balance job processing and increases availability
should one installation fail.
Important: Redundancy does
not provide failover capability or other high-availability capabilities.
It simply increases job-processing capacity. If one of the redundant
installations fails, all executing jobs managed by that installation
are lost, but the remaining installations continue to process their
executing jobs and accept new jobs.
When users start jobs, entries for the job are made in the database.
The process engine polls the database to see whether there are new
jobs. When there are multiple process engines, load balancing occurs
naturally because each engine polls independently during its non-busy
cycles.
When you set up redundancy, you perform a normal installation of
the management console, and then install the management console on
additional hosts. All of the installations are configured to access
the same Build Forge database.
Important: Every installation
must be installed on its own host. You cannot install multiple management
consoles on the same host.
