Goal

Q 1. Do you recommend setting _gc_policy_time=0 to disable DRM (Dynamic Resource Mastering)? Does BRM benefit from the DRM feature? If it has to disable DRM, how does the performance be affected at the DB side?

Q 2. Do you recommend setting _disk_sector_size_override=true? There is performance issue with redo logfile parallel write, how does this parameter affect redo log write?
