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!

Io exception: The Network Adapter could not establish the connection

Asked by ncsvietnam in Oracle CRM, Java Server Pages (JSP)

Tags: Oracle, JSP

Hi experts,

Please help me on the following strange problem. Thanks in advance!
My JSP Web application runs on Weblogic server (ver 8.3.1), uses Oracle 9i DB. It's main process is
- Step 1: Upload an excel file with more 11 thousands of data row in only one sheet
- Step 2: Read above excel file
- Step 3: With each row:
    + Parse it to build an appropriate object
    + Open a connection to DB
    + Call a stored function in DB to write parsed object to a table in DB
    + Close connection

I'm testing this application in two cases.
    Case 1: Running on Sever A, installed on machine A, using DB installed on machine B
    Case 2: Running on Sever B, installed on machine B, using DB installed on machine B
With Case 1, everything's OK but with Case 2, it throws SQLException 'Io exception: The Network Adapter could not establish the connection' at row 3938 (8 times per 10 times of testing).
So strange that it thows that error at rows below: (one case of testing)
- from 3938 to 5709
- from 6609 to 6633
- from 10937 to 11138

Please help.
Thanks again!
