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!

EJB Performance issue

Asked by kmapper in Enterprise Java Beans (EJB), J2EE

Tags: Java

Hi,

I have a XML file containing about 20K person names.
For each person I need to perform some update in my DB.
Then, when if the entire process completed successfully, I need to change a perform a final update in the DB. (I set a status - successfull)

The problem:
If I try to do all the process (20k persons) in a single transaction, I get a timeout exception.
So I splitted the TX in many small TX. One Tx per person.
Now, calling 20k EJB in a loop cause my application to slow down dramatically!!

Some guy told me to use a msg driven bean, but I dont see how this will solve my problem. Since I need to keep a trace of whats going on in my entire process in order to set the status (suddess/fail).

Someone have an idea?
