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!

Maximize performance of a Sybase Dump

Asked by knel1234 in Sybase Database

Tags: , , ,

Hi,

I am looking for ways to maximize the performance of a Sybase dump.

Environment/Background:
Solaris O/S
Sybase 12.5.x and 15.x ASEs
Databases 20Gb - 500Gb
Current Dumps are to Tape

Issue:  There is a time constraint for the nightly window

Current Scenarios:
Test have been run for 2, 4,6,8,10 stripes (note: 10 engines for the ASE)
Test have been run for compression levels of 0,1,2,4, and 6
Memory was increased
Combinations of these tests have been run

Base on the data collected.  There appears to be plenty of CPU, I/O, memory, and bandwidth still available.  However, Sybase doesnt seem to take advantage (need to utilize) these resources

Unfortunately, the results are not acceptable.  The tape drives are still completing this task in less time.

Any thoughts? Obvious or not&.

cheers
knel
