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!

Autoexend on datafiles

Asked by algotube in Oracle Database

Tags: autoexend, oracle

Oracle9i Enterprise Edition Release 9.2.0.7.0 - Production
PL/SQL Release 9.2.0.7.0 - Production
CORE      9.2.0.7.0      Production
TNS for 32-bit Windows: Version 9.2.0.7.0 - Production
NLSRTL Version 9.2.0.7.0 - Production

Hello everyone can someone please clarify how autoextend works.

I have these datafiles Storage:

Automatically extend datafile when full (AUTOEXTEND)
Increment 20480 K Bytes
Maximum Size
Value 10000 M Bytes

FILE_NAME                                                     SIZE (M)   USE(M)                                  
----------------------------------------------            ------------ -------
G:\ORACLE\PR3\SAPDATA1\DAT_1\DAT.DATA1   2000.000   1353.063        
G:\ORACLE\PR3\SAPDATA1\DAT_2\DAT.DATA2  2000.000    1848.063          
G:\ORACLE\PR3\SAPDATA1\DAT_3\DAT.DATA3  2000.000    1498.063            
G:\ORACLE\PR3\SAPDATA1\DAT_4\DAT.DATA4  2000.000    2000.000                
G:\ORACLE\PR3\SAPDATA1\DAT_5\DAT.DATA5  2000.000    2000.000              
G:\ORACLE\PR3\SAPDATA1\DAT_6\DAT.DATA6  2000.000    2000.000              
G:\ORACLE\PR3\SAPDATA1\DAT_7\DAT.DATA7  2000.000    2000.000              
G:\ORACLE\PR3\SAPDATA1\DAT_8\DAT.DATA8  1520.000    1512.688    
G:\ORACLE\PR3\SAPDATA1\DAT_9\DAT.DATA9  2000.000    1066.063

Does autoextend extend within each datafile?
When the USE(M) reaches the SIZE (M) does Oracle jump to another datafile which has more space?
If your using autoextend why do you have to manually add another datafile Oracle should create another datafile when needed.

Can someone please clarify.  We are debating this question and everyone has there own theory.
