I did some work at home over the weekend and it worked beautifully. I was impressed and couldn’t wait to wow my colleague. Now, time for the production server to play host, and duh! The application fell flat on it’s face. One, the <cfformitem type="text" and type="htm" refused to show. Two, clock icon continues ticking forever and three, worst of all, data wouldn’t load into the forms.
The honchos didn’t waste much time asking for my head on a platter. I started looking for answers. Didn’t get much except for a clue from Ray Camden about bad CFIDE mapping. I compared my settings with the dev servers but it was fine. Along the line, I discovered that only servers that were upgraded from CFMX6.1 have same problem (oh, my app was tested on all the servers in the world!). I did a double take; sent out an outtage report and downed the production server. Copied my settings, uninstall the CFMX7, deleted every trace, and reinstalled and presto, life came back to me. The app worked, the honchos smiled and I had a pizza.
The trouble came from a ‘wonderful‘ trick of replacing your CFIDE in wwwroot (default settings for Windows/IIS6 install) with the old one from CFMX6.1 when you upgrade to CFMX7. Because we are one of the early adopters of CFMX7 around my end, I just looked for what seemed to be the smartest upgrade method on fullasagoog. Only God knows who thought it was smart but I did it.
Since we have decided to use the AD as the user management foundation for the different web applications running on the network, it’s now so easy to write applications without worry. But won’t it be nice for users to login on one application and remain in session across multiple applications just like you have on yahoo, msn, windows network, etc?Why should a user login into different applications? It’s no consolation that the security credentials are the same.
Now, Windows have the same facilities, which is evident for those who have used Outlook Web Access (OWA). If you are authenticated against the domain in which OWA is residing, you wouldn’t be prompted to login again. I tried so much but couldn’t lay my hands on any reference. It should be some obscure ActiveX somewhere…
So I set out to design what we call a base/foundation service (BFS) structure. This is an application that authenticates a user against the active directory and keeps the session information in a database. When a user attempts to use an application, the app queries the BFS to know if the user is logged in and what the security credentials/profiles are. An application must be registered and talks via secured connection (web service over https) before it can query the BFS. The sessions are tied to machines and it has a scheduler that runs the timeout processes.
We use an oracle database so that the applications could survive a crash and also allows clustering. Coldfusion itself could use a database for session management in clustering.
Had to take a quick vacation to rest some parts of my aching body. It was really fun running away from work and getting paid for doing so.
Macromedia just released Studio 8, which includes the much loved/hated Dreamweaver. For me, the coolest additions are the XML and the zoom tools. Go to Macromedia to read more.
If you think only tech issues, budget, (nasty) bosses, etc can derail a beautiful projects, think otherwise. A nastier determinant is the Mozzy.
Mozzies are simply mosquitoes, especially the ravenous types, who think we human beings are the most delicious things walking on two legs. Get any of these dudes to bite a key guy on any project; the direction of the project days after is better left to imagination.
I recently got mugged by a group of very devilish Mozzies, had to spend two days at home recovering from their bites (and the resultant malaria..) while my outstanding deliverables were left undelivered in the office. What a shame!
