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!

Tempfs relationship to pga and  sga

Asked by jhucofsa in Oracle Database

Tags: SGA, PGA. Tempfs

I have a new Oracle 11 database using amm.  I do not understand the relationship between
the sga and pga usage and the  tempfs used.


MEMORY_MAX_TARGET  =       1264M
MEMORY_TARGET =       1264M

Output of v$memory_dynamic_components is
                                                                                   
COMPONENT                   CURRENT_SIZE           MIN_SIZE               MAX_SIZE

shared pool                 503316480              234881024              503316480

java pool                        16777216               16777216               16777216  
SGA Target                  872415232              687865856              872415232  
DEFAULT bcache         318767104              301989888              402653184  
PGA Target                   452984832              452984832              637534208  

df -  k                                                                              
tmpfs                  1310720    850672    460048  65% /dev/shm

Why is tmpfs only using 850672 which matches only the SGA?
