TM1Web server can't connect to TM1 Appl Server

[harrytm1]

Hi all,

Previously, the TM1 Application server and TM1Web server are both residing in the same box. Today, we decided to separate these two into two servers. The original physical server will solely be used to run TM1 Web (i.e. only Excel Service will be running). Let's call it "WEB".

We copied out the Data folder, cfg file and Log folder and plonked them into the new Appl server "APPL". It will be running Admin Service and the TM1 service.

WEB has all along been placed in the public zone as it always serves as a file server. Thus, overseas users can FTP files into it, as well as accessing TM1 Web through Internet. Users with TM1 client and reside within the intranet can of course access TM1 directly too.

So now, APPL is taking over the Admin Server and Application server role, and it is sitting in a more secured zone. After the migration, the Excel client works fine. However, when we tried to access TM1 Web through the public URL (which was working previously), the whole login page will take a long time to load when we enter the name of the application server "APPL" in the Admin Host field. Then, a message popped up and said something like "APIDOTNET ERROR" and something to the effect that it is taking too long for something to respond from a specified IP address and port number. Also, the Login button was disabled despite the TM1 server name being shown in the drop-down list. Sorry for not posting the image and teh screenshot is stored in another PC.

We suspect it could be due to the firewall as WEB is in the public zone while APPL is sitting behind the DMZ, and possibly the port number is blocked. We decided to test our hypothesis by switching the configuration i.e. letting APPL acts as Web server and WEB as application and TM1 server. We access TM1 Web with url pointing to APPL instead of the public URL (of course, since public url is set up to WEB). And it works, i.e. we entered WEB in the Admin Host and the TM1 server name is rerturned correctly, and this time, the login button is enabled.

So is firewall really the issue? What is the correct port number to use? Do I have to do anything to the web properties file in wwwroot/TM1 Web folder? I feel that it is not necessary to set up the Admin Host in that file as there is just one host anyway.

Please assist. Many thanks in advance!

depends on the used port numbers..

could be something like:

tm1server port e.g. 12345
5498 / 5495

everything tcp


the client works fine? on the websrv?

try on the websrv
telnet appl 12345
telnet appl 5495
telnet appl 5498

if you see a error its bad
if you see a black blank cursor blinking window its good..
