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!

Perl onSuccess method not returning status

Asked by voodoobamboo in Perl Programming Language, Bourne Shell (sh), Shell Scripting

Tags: perl, method, script, unix, linux

Good morning all....
I have been learning Perl for about 2 months now and I guess I am getting there as much as I can however I am really stuck. I have a Perl script called postEvent.pl which uses a package called event.pm. PostEvent.pl depends on a meithod inside event.pm called isSuccess to tell the user if the message sent was a success.

For some reason I keep getting....
"Problems sending message to Tivoli"

Which is coming from...

if ($event->isSuccess()) {
        &info("Message sent to Tivoli, $flags{'m'}");
} else {
        &error("Problems sending message to Tivoli, ", $event->getStatusMsg);
}

In postEvent.pl.


The problem is that the message is in fact a success, for some reason its just not getting the message that it was a success from the event.pm package and I am not sure why. I am listed both sets of source code here in hopes that somebody can tell me what I am doing wrong and show me. I have been stuck on this for 2 days now ;-(

Thank you.
