Dimension file checking mechanism

We had a case .dim file broken after a reboot, "broken" means we can start tm1 instanace with no any error related to dimension but we found some data loss when checking data from cube view, and we tried we need to retore .dim files from backup then able to see data normally, which means .cub files are still normally and we can confirm it's .dim files broken caused that we cannot see some data from cube view.


We had ever submitted a case to IBM support, the answer we received is there is no mechanism to check if a .dim file is normal or broken, we are expecting a mechanism included in TM1 for checking this and should return some error if some file is abnormal.

    Hi,


    The problem that we a facing is .dim got read and loaded into tm1 with no error but we were not able to see all the data in the cube, so it looks like "Data Loss", turns out it is broken .dim file that caused this issue.

    So what we need is not change tracking as you described, we need to know and receive some information from log file when this occurred.

    This idea is not under consideration. Consider using the GIT feature to store dimensions in GIT. This will allow you to determine changes between versions of the dimension and provide the ability to restore a previous version of the dimension.


    If the issue being reports is the TM1 database is not adding a log entry in the tm1server.log file when the .dim file cannot be read on startup, that is a defect.
