There were certain data changes in the cube , so I wanted to restore the cube for a previous time. While restoring I got certain messages like ess0001.dat in use , .otl is in use etc and below I had the option of Replace on Reboot for data file(.dat) and Outline file(.otl). Firstly I had stopped everything in Essbase but still I was getting this messages. At the end I tried Restore on Reboot , realized later that reboot happens rarely . So now i am concerned , when reboot happens my entire cube will be restored for today. But from today till the process of Rebooting happens there will be lot of changes within cube which will be reversed back to todays date . Is there any work around for this , Comments and suggestions please.
