The other day I was assigned the job of installing a couple of NAV 2009 (web) servers, which included setting up delegations. Lucky me. [:(]
I ran into an issue that kept me busy for almost 2 days which eventually ended in a, as so often, very simple fix. [:^)]
Of course to prevent you and myself from having to do this 2 days endeavor I'll share my findings below. If you can't hold your nerves just jump to my Long Story Short.
But maybe even more I am writing this story as an homage to all my fellow NAV pros that have consciously and, all but one, unconsciously contributed to the solution. Every workday I am grateful to all of you that share your findings on fora like mibuso, dynamics user and Microsoft Dynamics NAV Community even if you pose them as questions.
So here we go with my Short Story Long.
Here I am, setting up NAV 2009 (web) servers and delegations. Typically a task that I do not perform on a regular base and which often is a nuisance due to these delegations. But every time again I happen to get it working with valuable help of one of my IT colleagues, and so I am guaranteeing I will be the chosen the next time. [H]
BTW: needless to say that this all about a 3-box setup as described here.
This time the main goal was to get a NAV web server running to enable an external party to access our Dynamics back-end. Although we use web services heavily, our main installation is being accessed still by means of classic clients. But in the not too far future we will start running RTC and therefor, having installed the new web service, I wanted, in one go, to get the application service tiers running on our test and acceptance environments.
Easy said then done as it appeared.
Here starts the hunt for 'Mr. X'. Or actually '0x1C', as we will see. Even though we will not be using buses, taxis or the London Underground, we will hunt him down like the detectives in the Scotland Yard board game. We lay out the board and distribute the tokens and other accessories and confront the ...
Where did 'Mr. X' go?
After having installed the right RTC and Service Tier builds, and configuring the service, starting up RTC threw the following error.
A first sign of live from Mr. X. Speaking Dutch, by the way.
ENU: The server net.tcp://<Server>:<ServicePort>/<ServerInstance>/Service is either unavailable or your connection has been lost. Do you want to attempt to reconnect?[Note that I have replaced the server, port and instance names by generic terms.]
Clicking either Yes or No resulted in a follow-up message:
ENU: Lost connection with the server. The application is closed.
... to check was whether the service was still running or not: it appeared to be running.
No sign of Mr. X. Where did he go?
Luckily I always install a full demo version on any NAV environment, be it development, test, acceptance or production. On the default port (7046) the application service for the demo database is running, while on another port (for example 7066) I can access development, test, acceptance or production database. Would I be able to access it? In order to check that the ...
... was to change the ClientUserSettings.config so that my RTC would be looking at the demo service tier (<Server>:7046/DynamicsNAV/Service) and run RTC.
Splash screen, as always slow, keeping me waiting ... and ... keeping me waiting ... and ... keeping me waiting ... and ...
Alive and kicking! Clear that delegations were not blurring things. Although I still had to check whether using a fully qualified DNS would also work OK.
Entering the fully qualified DNS in the Select Server window and pressing TAB showed the available companies in the demo database. Clicking OK resulted in a perfectly normal start-up of my RTC.
Would I be able to do the same with the fully qualified DNS for our test database?
And get closer to my Mr. X?
Didn't halter too long and did the ...
..., i.e. entering the fully qualified DNS for our test database and pressing TAB. Wow, connected to the service tier!
Mr. X, we feel somewhat close to you, but are we? And how to get closer now that I ran out of my first options. What were you actually saying?
Clicking however, threw the next error.
The server net.tcp://<Server>:<ServicePort>/<ServerInstance>/Service is either unavailable or your connection has been lost. Do you want to attempt to reconnect?
... if you can find it. Well, let's at least attempt to. Google is your Friend, isn't he? Straight around the corner.
Google, let's frame Mr. X.
What did you say? Trying to solve one riddle, getting another in turn? [:^)]
Google: The server net.tcp://<Server>:<ServicePort>/<ServerInstance>/Service is either unavailable or your connection has been lost. Do you want to attempt to reconnect?
OK, makes more sense. Let's click on it. Aha, my dynamicsuser friend Manish found a solution to this error. Indeed my default RTC profile was set to PAG50175 (part of our customization), so I changed it to one of the standard pages: PAG9006. No luck. Still getting the same error. To be sure I even removed all the records in the User Personalization (TAB2000000073), but to no avail.
Google: RTC Error “The server <address> is currently not available”
Next hint, you mean?
Well, glad you lead me to my dear fellow MVP Arend-Jan Kaufmann. Always providing valuable, and often technically detailed information. But no, this is not the issue. I know by heart we have the same build running on all machines. OK, I check it once more ...
... maybe I accidentally run into Mr. X. [H]
Back again, Google, and no, found nothing valuable.
And surely no Mr. X.
Got some more riddles for me?
Error: '┴' invalid character
Nope, doesn't seem what I am looking for. No clear cut fix.
In hindsight it was more or less what I was looking for. I was actually sitting next to Mr. X!
It surely pointed out me to have a look at the Event Log; as with the next as with Google's next hint:
As with the previous hint it was too much info in that error message. However this had some clear suggestions which at least I could give a try haven't succeeded so far. But before continuing my search I decided to ask Arend-Jan for help by sending him a mail with the event log file. If I wouldn't find a solution over time he might.
I recon meanwhile Mr. X was laughing in his sleeve making sure I could not hear it.
So based on Google's last hint decided to remove all records form the Object Metadata table and recompile all objects. I guess I was somewhat overreacting by removing all records. Just tired of searching and really getting closer to a solution. Starting RTC again I was welcomed by the next error of which I totally forgot to make a screen shot:
---------------------------Object of type Table with id 2000000045 could not be found.---------------------------
Mr. X has left the room!
Ouch, I am drifting away.
Half an hour later I found myself back on track, again getting some help from another of my fellow MVPs, Saurav Dhyani, on rebuilding the metadata. Don't know why, but this however lead to a Change Listener issue. After solving this and again compiling all objects ... I found myself having a deja vu: I was looking at the initial error again. [:@]
This suggestion from again a fellow MVP, Natalie Karolak, also didn't help me out either unfortunately even though it might prove valuable in the future.
And then I received an answer form Arend-Jan actually not doing much more then focusing on the invalid character as already mentioned above.
Arend-Jan Kauffmann out pointed that this was the crucial clue in the Event Log. He wrote:
Apparently the XML data, that is generated by the NAV server and sent to the RTC, contains a character that is not supported by the RTC. Probably some strange character in a caption or so. Or something else in the data.
Actually seeing our Mr. X almost straight in the eyes, but at the other site of the river Thames.
Within reach, but not ready to grab.
Mr. X, or, as mentioned before, Mr. 0x1C, being an invalid XML character, made the start-up sequence of the sequence of the RTC stop, resulting in this useless message:
Mr. 0x1C was clearly misleading us.
But still needing to find Mr. X.
How was I at long last able to grab him "by the collar"?
Using the Visual Studio Find in Files feature with the following regular expression [\x00-\x08\x0B\x0C\x0E-\x1F] being the illegal XML characters one object file popped up: MEN90.
It thus eventually turned out that Mr. 0x1C had been unconsciously and unintended placed in the Name property of one of the MenuSuite items the week before. Waiting to get out and get me busy for 2 days trying to trace him down ... by talking plainly nonsense.
A big thanx to all my fellow NAV pros that have consciously and unconsciously contributed to the solution. Of course one special thanx to Arend-Jan.
Hope you can profit from my findings as already one of you did.
Oh, one note to be made before I go: the most time consuming part of this endeavor was having to restart the RTC over and over again. Well actually not just restarting but needing to revert the ClientUserSettings.config ... Can't this be made somewhat simpler, MS?
I don't know. Maybe it's just me. Every once in a while, when writing, I get lost in spelling out right the word(s) I am writing. My mind somehow blocks and doesn't do what it normally does automatically. Just like this week, when I needed to translate some captions. More precisely a number of options that were only provided in NLD. So I had to translate them to ENU. It happened with one of the options, namely Geannuleerd.
Geannuleerd is the NLD word for Cancel... Wait ... [Halter] ... Geannuleerd is the NLD word for Canceled ... Or is it Cancelled? I never had thought about, i.e. I never had haltered over, this one before. While writing this right now I actually wonder why I haltered, but I clearly did. If I would have been doing this task now I would have written Canceled straight away.
The funny thing is that, instead of using Google translate, which I do by default and would surely give me the ENU translation, I took a total different approach. I used NAV to help me out. True, this wasn't the first time, but it revealed something totally new to me. No, not really earthshaking, but nevertheless a funny insight.
As you might know by now I am a big TFS user, so I always have (a copy of) the NAV code I am working on/with stored on my laptop in text files. So I took the approach of searching through these text files by means of the search box in the explorer, assuming that this search would tell me which of the two would be right. Cancelled or Canceled.
Well, have a look.
Cancelled or Canceled, that's the question!
Even NAV won't tell me. OK, statistically it would be canceled (110 occurrences) and not cancelled (45 occurrences). So that's what I used right then, not spending more time on it thinking somewhat vague that this might have to do with ENU against ENG.
Now elaborating somewhat more on it here I found Google suggesting me canceled which then probably is ENU. Searching the Internet I also ran into this, which doesn't put a clear cut between the two, but surely eases my mind. But ...
... find myself still wondering why NAV utilizes not just one of them.
While performing a C/SIDE development training - like I am doing right now at Housing in Ljubljana, Slovenia - I am always searching the internet for articles. To provide my students with articles that complement the standard resources and training material. But often, and not in the least, as an answer to the never drying out source of questions students seem to draw from.
Doing so, I often run into the same resources: the still improving help of NAV, NAV Team blog, mibuso, dynamicsuser, fellow MVP blogs, etc. But every now and then I am taken by surprise, like this early morning. Browsing around regarding dimensions, I stumbled over this post: NAV Dimensions - The Theory by Gemma Warren. She made me smile. Thanx, Gemma.
Until this morning, you were totally unknown to me even though your blog has been around somewhat over a year already. Maybe because I am primarily a technical guy and you a functional ... girl. Only God knows, I guess. Nevertheless, it's surely worthwhile reading.
So: Welcome to the Dynamics blog-o-sphere!
At the danger that it will become a normal thing Microsoft has awarded me for the 5th time in a row the MVP Award for my community work in the year passed. And with me 984 exemplary community leaders around the world, among them my dear Dynamics NAV MVP fellows Mark Brummel and Eric Wauters.
But indeed it isn't "a normal thing" and like every year I am thankful for being in this position and still being able to be in this position. Not in the least due to all those that ... support me (thanx, Saskia et al.), ... I work with, ... ask me to help them out, ... I luckily run into and learn from, have fun with, etc.
So again: a big, no a VERY BIG, hand to all of you.
