Rendition Engine in a highly available environment

You can install Rendition Engine in highly available configurations by using the standard Rendition Engine installer. No extra software is needed to set up a highly available Rendition Engine. FileNet® P8 relies on the built-in LIQUENT high availability.

In a highly available IBM® FileNet Rendition Engine environment, a number of Rendition Engine servers share the rendition administration and workload. Together they provide redundancy in the event of network or server failure. The LIQUENT InSight Rendering software uses a LIQUENT Vista domain to track all render servers that have been configured and joined to the domain.

Each Rendition Engine, controlled by the LIQUENT Vista domain, polls the Rendition Engine database for submitted rendition jobs in a round-robin fashion. If a job is available, the LIQUENT Vista domain assigns it to one of the available Rendition Engine servers. In this scenario the LIQUENT Vista domain, distributed across the available Rendition Engine servers, acts as a “load balancer” and assigns jobs to active Rendition Engine servers.

If a Rendition Engine server becomes unavailable, the available Rendition Engine servers pick up the workload. If a server becomes unavailable during rendering, the job ticket will fail, and a timeout will occur on the ordering Content Platform Engine server. After the timeout, Content Platform Engine resubmits the job once before signaling an error. The new job is picked up by another Rendition Engine server.
