TM1 Forum

Hi all, if you can give me some help

I have TM1 9.5.2 FP2 installed on my windows vista machine. Prior to upgrading to 9.5.2 and 9.5.2 FP2, I had a working 9.5.1 contributor application running on top of tm1 instance 'A'

Now, I want to run 2 TM1 instances ('A' and 'B'), use the existing contributor application on instance A and make new apps on instance B. However, I do not manage to create any application using instance 'B'. There are 2 conditions that produce errors

1. Instance A and B are running (I could login to both instances using Perspectives, using the same user ID). I manage to login to contributor successfully, and could see and open existing application on instance A. Then I start the Design Application to create a new app on instance B.

When create new planning application dialog appears and i input the app name, select the tm1 server name (instance B) and click ok, I always get error message: The application will now exit as the connection with TM1 server was interrupted, and then TM1 contributor administration tool is automatically closed

2. If only one instance is running (instance B), I am never able to login to contributor page. I always get message: Could not logon to any available servers with the provided credentials

In summary, it seems that i have to start tm1 instance A to be able to login to contributor, even though it is successful, i still could not create application on instance B

Thanks

TM1 Contributor inherits the security mode of the first TM1 instance that you attach to it. Thus all TM1 instances attached to one TM1 Contributor instance must be configured to use the same security mode as the first TM1 instance attached to that TM1 Contributor instance. If you intend to use TM1 instances being configured for different security modes, you must group these TM1 instances by security mode and attach each group to their own TM1 Contributor instance.

For instance:
The first time you attach a TM1 instance to TM1 Contributor, if that TM1 server is configured to use TM1 Standard Authentication (IntegratedSecurityMode=1) then all TM1 instances added afterward must be configured to use TM1 Standard Authentication too.

Hi

Thanks for your explanation. However in my case, the security modes of both instances are the same. I use IntegratedSecurityMode=1

I manage to make it work but not sure if this is the right way to solve this issue.

I took the control objects that are related to contributor (with }tp in the file name) from planning sample database and copied them to my data directory
Restarted the Tomcat server

Hi Moby,

I read your explanation regarding TM1 contributor getting attached to the security mode of the first TM1 server it is configured with.

I recently came across a similar issue, where the TM1 contributor was already configured with several TM1 servers with Security Mode =1 and wanted to configure another TM1 server with security mode =5, using cognos security.

When all the settings were in place, the contributor URL kept directing TM1 authentication page instead of Cognos Login page.

When the same server was configured with new contributor instance, it worked properly.

The IBM documentation states to use a single auth mode per contributor, but I did not find any documentation revealing what happens when we try to use different TM1 servers with different security mode in a single TM1 contributor instance. Do you have any such documentation handy ?

Thanks in advance.
