Hi Suresh, Thanks for the feedback. I suppose that we should define media recovery and crash recovery. My understanding is that media recovery is when you have lost your logs as well, whereas crash recovery is when the logs are intact. In case of media recovery, does Derby know how to locate the last checkpoint record/log file? Regards
