Troubleshooting
Problem
User launches "IBM Cognos FAP" from the start menu. The Controller "Financial Analytics Publisher" (FAP) Window appears. User starts a publish. User clicks the 'logs' tab. After a few seconds, an error appears.
Symptom
FAP Client:
Inside the "FAP Client", inside the 'logs' section there is an error with 'Severity' set to "CRITICAL". The Description is similar to:
- Could not login to TM1, host: <servername>,
server name: <TM1_service_servername>, user name: <domain\username>
When the mouse is hovered over this error, the following message pops up:
- SystemServerNotFound
Cause
There are several causes for the generic error 'Could not login to TM1'.
- TIP: For more examples, see separate IBM Technote #1664572.
This Technote specifically relates to the scenario where the TM1 Server has been restarted. This has caused the FAP<->TM1 communication to become invalid.
Real-life example:
In one real-life customer example, the TM1 server had automatically restarted/rebooted itself (e.g. because of automatic Microsoft patch updates).
Resolving The Problem
If servers/services are restarted (or server machines rebooted) you have to restart servers/services it in a specific order (to keep the FAP-TM1 communication in valid state):
- Stop the FAPService
- Stop the TM1Server
- Start the TM1 Server
- Start the FAPService
Note:
Each of these steps may require a short amount of time (e.g. two minutes) to complete its task.
- Therefore, please pause for a short while (e.g. 2 minutes) between each task.
In addition, there is a recommended method to ensure minimal loss of service between reboots
- Therefore, see separate IBM Technote #1585881 for more information on TM1/FAP reboot best practices.
