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!

Deleting 100 million rows from production table

Tags: oracle, oracle 10g, 10g
I'd like suggestions to delete about 100 million rows from a table that has currently about twice that amount.

The table has an id variable and we wish to delete from id=1 million to id=2 million (so approx there are about 100 rows for each id)

The principal constraints are that this is a live 10g  system and so we dont wish to interrupt usage although we would like to do this when the usage is low.  

How long should this operation take?  Suggestions for speeding this welcome (I presume that deletions will be done for some subset and committed and so on in a loop)
