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!

How does the UTL_HTTP package use Oracle Net

Asked by mmoore in Oracle Database

Tags: , , ,

I am using a command like

   UTL_HTTP.set_transfer_timeout (5);

   SELECT HTTPURITYPE.createuri
             (   'http://fluffy.sf.nowhere.net:8080/rodger-admin/manageCacheFull.do?userName='
              || 'myuser&password=password&action=update&cacheName=com.rcom.tarcaptu'
              || 're.prxcommon.entity.RTotal&cacheKey=9'
             ).getclob () web_page
     INTO l_web_page
     FROM DUAL;

What does TNS have to do with HTTPURITYPE (which is really utl_tcp in a wrapper). I don't understand how TNS gets involved. It would seem to me that the implementation of utl_tcp which in written in C, would create the necessary socket etc. I understand how Oracle Net gets involved for inbound HTTP connections but for outbound connections it doesn't make any sense.

ORA-29273: HTTP request failed
ORA-06512: at "SYS.UTL_HTTP", line 1674
ORA-12535: TNS:operation timed out
ORA-06512: at "SYS.HTTPURITYPE", line 34
ORA-06512: at line 6

As a side note, the error takes  3 min 44 seconds  before it happens.  It should take  5 seconds to time out, because of  the  UTL_HTTP.set_transfer_timeout (5); command.

The Question:
How can I ensure that control returns to my PL/SQL process after 5 seconds.
