TM1 Forum

when scheduled nightly TM1 chore ran to save data all on server TM1 failed to load data from ram to disk as a result TM1 server went down .
when i looked at TM1 logs i was able to see

ERROR 2013-09-13 20:29:58.312 TM1.Blob CommitDeferredFileCommand - Open failed: err=5 system_err_code=5
ERROR 2013-09-14 07:00:43.757 TM1.Server sf_Rename: Failed to rename (g:\tm1\logs\tm1s.log) to (g:\tm1\logs\tm1s20130914070001.log). Error: Access is denied.

When i restarted TM1 server TM1 clients and groups went missing from server( except Admin client ) .
I copied clients properties cube from differrnt environment and reconfigured clients to concerned groups manually to fix this issue .

Does any one know extract reason why clients went missing from server .
Does any one encounter similar issue.

I am using TM110.1 on windows R2 2008 enterprise with no excel on the server

i included screenshot of TM1 logs in two instances .

Thanks for your time in advance.

Hi Jodha,

The most likelihood of this that the TM1 server did not commit to disk properly (hence the error in the log) and corrupted your {Client control files. When this happens you should see the .Cu$ or .Di$ in your data directory. Renaming them usually does the trick.

I would also check to ensure you have available hard disk space, just in case.

It might be worth checking if there is any anti-virus running too as perhaps it was scanning the TM1s.log file, hence giving you the access denied error.

Hope this helps
