Configuring the IOR cache (high availability environments)

(F5 using 3DNS for load balancing by DNS routing) Configure the IOR cache time-to-live for applications accessing a farmed Process Engine.

In a farmed Process Engine environment where you use F5 for load balancing by using DNS routing and the 3DNS method, you must configure the client machine IOR (Interoperable Object Reference) cache time-to-live to a value smaller than the default 3600 seconds, matching the DNS TTL set for the 3DNS. Having a cache time-to-live that is longer than the 3DNS TTL will cause the calls to be routed to only one Process Engine server instead of the preferred Process Engine server as intended by the 3DNS routing. The cache time-to-live is set by using the system property filenet.pe.ior.cache.ttl.in.seconds.
The configuration is required for the following components:
  • Content Engine
  • Application Engine
  • Component Manager on Application Engine (configuration done post-installation)
  • Workplace XT
  • Component Manager on Workplace XT (configuration done post-installation)
  • Custom client applications that use the Process Engine API.
