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.

MySQL Replication

Asked by Fatlog in MySQL Server

hi,

i've a general question regarding MySQL replication.

we have an application that is currently setup to run on 4 servers. Server 1 hosts the MySQL Database and serves up pages via Apache that connect to the Database. The other 3 servers run an application that also connects to the Database on server 1.

The load on the databnase can vary but on rare occasions it gets very high. running a TOP command in linux on Server 1 reveals the MySQL CPU usgae can exceed 100%. This at times results in MySQL "Lost Connection" errors. So obviously this setup needs some improvement!!

I'm looking at reducing the load through the various scripts running but i also want to have the Database setup in the most optimal way.

So in general would replication help in this scenario?

If so, Would it be best to have a single Database replicated from the main database on server 1 or would it be best to replicate the main database out to a salve version on each of the other servers.

When replicating how much of a load does it add to each server?
And how often can the replication take place?

all comments welcome!!

thanks
