I am also using OBIEE 11g. We have set the loglevel for the user as 4. Also cache is disabled. Default Logging level is also set to 4. However when we try and open the log from Administration -> Manage Session. It gives 'No Log found'. Has anybody found any solution for this.
It is still happening, though not every time, in 184.108.40.206.0. I've asked the Admins on my project to look at this thread on some of the suggestions. However, should this be completely corrected in this version? Or are there additional settings needed?
