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!

Well, first off it will depend on the following answers;

1. TCL or JSP sites?
2. Version 6.0.? (I can't remember if 6.0.7 is the latest or not)
3. During last upgrade were the CDS's upgrade to allow use with V7? (option called during upgrade)
4. Database type being used (Sybase, MYSQL, DB2, Oracle)
5. Application engine (Weblogic or WebSphere) and which versions.

Depending on the answers above will dictate some of the issues you may have. For example, there is no TCL in V/7 so total rewrite would be the option. Etc.....

Thanks dgbaker for responding. To answer your questions:
 
1.  Going from TCL to JSP, so that means replacing all the TCL as you mentioned.  Is there any technology to do this?
2.  Currently running version 6.0.5
3.  I believe that you currently can use the v6 api with v7 but that is not going to be supported at the end of 2006.
4.  Using Oracle
5.  Using WebSphere

One of the issues that I am aware of is the caching issue.  Have to find an alternative.

There have been attempts to convert from tcl to jsp programatically but without much success. It is generally accepted that to go from tcl to java (V7) you need a total rewrite.

For the API, yes I think you are correct on that for the date.

Oracle and Websphere are good choices with the following caveats.

V7 is now pre-bundled with Weblogic for the CMA (cannot change that)
Java 2 security can be an issue with some of the V7 Testing tools. ( See Vignette KB Item: 6030)

If you are looking at a migration as opposed to net new, then I would use VPS for help. I personally would look at using this exercise as a way to cleanup and start fresh. With all of the changes (complete rewrite) of the Vignette platform, I would note feel comfortable with a migration.

Because there are so many different configurations and coding that can be done I don't think anyone can say for sure what issues will run into. We ourselves have run into issues that have never been encountered before. The other thing of note I forgot was that it also depends on the O/S, I think MS or Solaris are the better for this.
Accepted Solution
