1 web to 2 engines

Kaman_Paul

I have 1 WFE and 2 APP (Engine Only) servers.

So in 9.1 the Engines are the only location for the EngineServiceConfig.xml.  And the web.config (on the WFE) references the EngineServiceConfig.xml.  My engine config files list both engine servers.  But the WFE only as one value for engineServiceList.  At the moment I do not have any NLB or Pooled IP for these two engines.  You don't need it for the EngineServiceConfig.xml.

But the problem is the web.config on my single WFE.  If it can only reference one Engine, then if that Engine is down, how does the BPM web app know to look for the other engine?

There documentation does reference a scenario of Server A (web / app) and Server B (app only).  And this scenario removes any particular config with the web.cong on Server A.

So question: can you list multiple Engines in the WFE's web.config if the Engines are split from the Web entirely?

Thanks,
Paul

Hi Paul,

 

Instead of using the engineserviceconfig.xml on the engine server via http point the web.config entry  in your web client web.config to a file location on the web client web server. You can copy one of the files from the  iisextension folder to e.g.  c:\.....bpm\web\engineserviceconfig.xml.

 

In your engineserviceconfig.xml you have then two entries for your engines. If one engine goes down the system takes care of it and the web client will then only connect to the other engine server until the broken one is working again.h
