Its observed that when HDR is lagging behind the primary there are number of sessions goes into " G waiting on write of the logical log buffer" and primary goes slow and lot of load on primary until unless secondary completely synch with the primary. Is there any bug in this version,Because we were facing some like this problem with rss in 11.5.FC6 Any body can guide me to resolve this issue or any database tuning to overcome the problem . Thanks in advance. **************************************************************************** *** Forum Note: Use "Reply" to post a response in the discussion forum. **************************************************************************** *** Forum Note: Use "Reply" to post a response in the discussion forum.

This is an issue with HDR since version 6.0. It's just that processors have gotten much faster since the 6.0 days and exposed the problem. Also we have been focusing on improving performance on the server in general and added to the possible exposure. M.P.
