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

While I have not done this in V9 (yet), I did just finish doing this in V7 and I would suspect V9 would be similar or the same.  Each of our engines also have the WFE local.

I built out a sepearate WFE in an attempt to increase user performance in Asia.  On that server I have its own Engine config file where each of the engine machines are listed.  Thus far, it seems to be working fine.  (We're still testing to find out if performance is increased or not.)

We also have a separate 7.6 environment and I noticed that in this install, the EngineService (escripts / IIS Extensions) web site gets installed in the WFE.

But in 9.1 if you separate the Engine from the WFE, you do not get escripts installed on the WFE.  Or it gets installed but with no content (folder is empty).

So the only location on the WFE with a reference to the EngineServiceConfig is the web.config.

I'm wondering if I need to setup the escripts web site on the WFE as well?  It is seeming like I should.

Thanks,
Paul

Just had a call with MBPM support and confirmed that escripts (IIS Extensions) needs to be installed on the Web Front End.

This makes sense as otherwise the web can only connect to one engine.
