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!

Recommend Cache configuration settings

Asked by roymagi in Sybase Database

Tags: Sybase

Hi,

We are using Sybase ASE 15.0.3.
I need clarity and recommendations for setting up cache configuration for a consolidation activity.We are talking about 300 GB of data pumped from one db to another using slow bcp.
The test environment has the below settings:
sp_helpcache
Cache Name      Config Size      Run Size      Overhead
default data cache      2000.00 Mb      2000.00 Mb       226.97 Mb
Memory Available For      Memory Configured                  
Named Caches              To Named Caches                  
--------------------       ----------------                  
2000.01 Mb                  2000.00 Mb                  
------------------ Cache Binding Information: ------------------                  
Cache Name           Entity Name                Type               Index Name                    Status                  
----------           -----------                ----               ----------                    ------            
sp_cacheconfig
A      B      C      D      E
Cache Name      Status      Type      Config Value      Run Value
default data cache      Active      Default        2000.00 Mb        2000.00 Mb
                                   ------------ ------------                        
                            Total    2000.00 Mb   2000.00 Mb                        
==========================================================================                        
Cache: default data cache,   Status: Active,   Type: Default                        
      Config Size: 2000.00 Mb,   Run Size: 2000.00 Mb                        
      Config Replacement: strict LRU,   Run Replacement: strict LRU                        
      Config Partition:            1,   Run Partition:            1                        
                        
IO Size      Wash Size      Config Size      Run Size      APF Percent
    2 Kb           61440 Kb        1600.00 Mb        1600.00 Mb          10
    4 Kb           40960 Kb         200.00 Mb         200.00 Mb          10
    8 Kb           40960 Kb         200.00 Mb         200.00 Mb          10
(return status = 0)                        

Configuring a 16 kb pool would give beeter results?
Having a log cache is better?(since we r using slow bcp and it would be logged?

Would be grateful if experts can give me a detailed explanation as I am a beginner with DBA aspects.
