Well at first, move ahead, edit Serverdocument, load rdebug (meantime solve some connection issues because of 3 different IP Interfaces and rdebug binding to the wrong one ...), prepare the agent, connect to Remote Debugger, select database ... where the hell is the agent ?
I've no clue, what finally brought me to the solution (after crawling through some TNs), but I simply moved the database to the server's root directory. Voila !
Seems like the Remote Debugger is not able to handle databases in sub-directories ... bug or feature ? ... I have to think about it ... :cry: ... annyoing ...
