configure AWS ELB for HTTPS offload with JDE

I’m configuring AWS for a new client implementation, of course this needs to be highly available and DR-erable…  You know what I mean.  My definition of DR is across availability zones, they are separate everything, so that is enough for me.  I don’t need cross region.

I have installed two separate web servers, both listening on port 9005 https and 9001 for http.  I’ve configured my AWS ELB to point to these two nodes.  I had to load the SSL cert into AWS, so it’d do the cert offload and the https work.

To get port 9005 working https, I needed to do the following for my JD Edwards server (within AWS).  I’m using a port above 1024 because of all the root restrictions on the server for ports below that number.

Note that you need to make the 3 distinct changes listed below:  Note that this is for JDE server, not AdminServer as stated in many documents.

Note that Although I’m doing SSL offload, I still need to configure the AWS ELB to point to a secure port in JDE.  I had a bunch of problems with https/http redirects.  It seems that there is something that does not like holding the https tunnel….  So, when the ELB redirects to JDE on HTTPS, all is good.

I also had to defined a custom affinity rule based upon JSESSIONID for the ELB in AWS.  This allowed JDE to work properly.

so now, when I log into my custom URL, I get presented with an https login screen and this is maintained in the application.

Above is the redirects and where they are going from and too.

Let’s summarise with a bit of a lesson:

Only install a single JVM / end point for JD Edwards in WLS in AWS if you are going to use ELB and any sort of elasticity.  Why?  Because the ELB can only really forward to a single port per host… So cookie-cut your web servers to be awesome at single port provisioning of E1 (they could do AIS too)…
