Troubleshooting
Problem
Customer would like to reboot their FAP-related servers (Controller application server and TM1 server). However, if they restart servers/services in the wrong order, they notice that the FAP publish stops/fails.
=> Question - How can the customer reboot FAP-related servers, without breaking the FAP publish?
In other words, how can customers reboot servers without needing to perform a fresh/new Initial Publish (which can take hours for large data selections)?
Symptom
Example:
Imagine a scenario where:
- Customer stops both the TM1 instance (sometimes known as a 'TM1 server') and the Windows service "IBM Cognos FAP Service" (also known as the 'FAP Service')
- Customer now starts the TM1 instance, but the TM1 instance has a task to perform (for example reloading its saved cube data from disk) therefore it will be some time (for example 10 minutes) before it is ready
- Before waiting for the TM1 instance to be ready (in other words, the TM1 service is still busy reloading/processing a cube) the customer starts the Windows service 'IBM Cognos FAP Service'
The above actions will cause the FAP service not to start properly.
- For example, there may be the following error (when the user launches the FAP Client): "It seems that no FAPService is running or FAPDb is started/restarted after FAPService".
- Alternatively, customers may find that the trickle updates no longer occur as expected (the FAP cube fails to be updated when the source Controller data changes).
