The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

sql2005 mirroring issues

Asked by motioneye in MS SQL Server

Hi,
I have encountered problem with mirroring which caused db connection freezes, when I check from sys.dm_exec_requests it was found below wait_type caused the problem, I killed the process but it just hung without releasing the sessions, now I wonder if Mcsft had any improvement on wait_type DBMIRROR_DBM_EVENT which I found always be the performance culprit

spid   kpid   blocked waittype waittime             lastwaittype      
------ ------ ------- -------- -------------------- -------------------
21     5524   0       0x008A   136737968            DBMIRROR_DBM_EVENT

82     8716   0       0x008A   136737968            DBMIRROR_DBM_EVENT
