I know it's a long shot that there might be any uniPaaS developers on here, but here goes:
Today for the first time I've gone to duplicate a system we have in uniPaaS 1.5.
In the uniPaaS broker, I added the flag /ApplicationPublicName to change the
APPNAME that the application responds on.
However, the AppName() output that the application generates is still the
original name of the application, not what I specifying as the
ApplicationPublicName.
Our system relies heavily on AppName(). Is there any way to get AppName() to
return the same value as /ApplicationPublicName?
Better late than never to answer your own question I guess.
To work around this, we internally depreciated the use of the AppName() function, and instead replaced it with our own IntAppName(). Our new function does an INIGet('ApplicationPublicName') and returns that, as AppName() seems to always be fixed to the name of the application when it was compiled.
This was 4 years ago on 1.5 - perhaps v2.0 is different now, but we have continued to use our internal function without issue.
