Sat, Mar 11th 2017 7:42p   Dave Hay
I was writing a generic ( use anywhere ) script to add a BPM URL to my IBM BPM Advanced 8.5.7 environment.For me, all of the components ( IBM HTTP Server, WebSphere Plugin and WebSphere Application Server / BPM ) are on the same VM.For the record, I'm running the VM on OpenStack.Therefore, I wanted a script that would get the hostname of the VM on which IHS/WAS is running.This served as source: -How can I use Python to get the system hostname?and this was my test script: - foo.jy import socketh
