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!

Oracle 10g How do I resolve ORA-04030 out of proces memory error on XML DB

Asked by drlchen in Oracle 10.x, PL / SQL

Tags: , , ,

Hi

I have a stored procedure that uses the XMLQuery function (SELECT XMLQuery( '......' RETURNING CONTENT) FROM dual; ) to extract data from 3 different tables and store the xml file in XML DB. This store procedure was running fine for a long time until 2 weeks ago where I started seeing the following error:

Database Error: DBD::Oracle::db do failed: ORA-04030: out of process memory when trying to allocate 92 bytes (koh dur heap d,qmxtkWriteXobToOpn:heap)

Currently I have 16,000 records. I am not sure what is going on, the size of the previous successful output xml file is about 2M. I also noticed when the stored procedure runs with 3G of system memory available, it basically used up all the memory and cpu time. The store proc consistently dies after 3.5 hour and spits out the ORA-04030 out of process memory error.

Does anyone have any suggestion what to look for or what parameters I need to set? Thanks
