Halo all
i can understand that this SOA appliance provides security features, data transformation and content based routing facilities. has there been any case of successful implementation of this box in the project so far. if so can anyone post the best practices regarding the usage of this box.

thanks in advance.

I have setup XI50's in lots of different environments the best practices are still being developed and its more of a case by case thing.  If you have any specific questions I would be happy to help.

Hi Lord

We are starting up a project and involving data power in it. we are in a stage of finalizing a transformation engine. I guess you must have taken up a survey at the earlier stages. So based on the experience can you tell which among this two (contivo or WTX) is best suited based on the factors:

1. ease of learning
2. cost effectiveness
3. transformation/processing speed

please post some links or references which could help us to read through the comparison summary about the two products WTX and Contivo.

Thanks in advance

 So this is a really complex question and goes to the base of why I started this forum (that there is no info on DataPower on the web out side IBM's site) but I will address each of your points...

1) ease of learning
 I have worked with both. They both have different approaches... If you have any experience with one I would go with that. Other wise WTX is an IBM product so when (no if) you run into issues its one source for support witch will make your life allot easier.

2) I am not sure of the pricing of Contivo these days but WTX design studio (this is all you need you dont need the server part) retails for about 3k a seat. The feeling i get is that Contivo is alot more.

3) speed...
I have no info on this from my understanding of how DataPower utilizes the maps I would tell you that the speed is probably almost exactly the same. DataPower compiles its maps and once they run the first time I think they are the same.  As far as numbers IBM doesn't publicly  post any numbers and you would need to basically POC your flow with your transforms and they would do some very pointed performance tests for you.



So that being said what data format are going from and to? whats your goal TPS? how many datapower do you have plan to have?

Thanks for the information B.

We are currently looking for SOAP to OAG transformation. We run a middleware business. We are trying to replace this (or enhance this) setup with the hardware Middileware Smiley I could find any case study as to how to couple WTX or Contivo with Datapower and exploit their respective features. Looking for help.

Thanks in advance Smiley

Not familiar with OAG do you have any links to what that format looks like.

If your just doing XML to XML i would recommend XSLT and not using contivo or WTX. If the mapping gets complex i would recommend any xslt mapping tool.  Given that I can give you some ruff performance numbers... TAKE THESE WITH A GRAIN OF SALT  but i would say with messages in the 5-10K range you could easly do 1500+ TPS depending on what else DataPower was doing.

Hi....
XSLT tool? i dindnt understand what is this. you mean the transformation engines i mentioned. Again:

1. we have xml to xml transformation, in addition we have transformations from xml to other half a dozen data formats.
2. Looking for some help regarding coupling datapower with WTX or Contivo. Please help with any reference illustrating transformation using these transformation engines and using the same in data power.

Hello all!!

I  have been using Contivo to map our transformations for some time now.  Contivo can generate the transformation from the map and datapower provides an interface to test the transformation on the appliance.  The XSLT's that are generated in no way take advantage of any dp extensions.

You can test an existing XSLT using and xslt tool like XMLSpy with the datapower xmlspy tool.  Or you could create a policy that will execute the xslt on the appliance.

Contivo and TX are both good products so the thread regarding familiarity with the tool could be the deciding factor for you. Contivo has alot of already created templates which is a nice value add. IBM though is developing and pushing TX as the transformation tool in their SOA toolbag so if your organization has standardized on IBM suite of tools for development it is a pretty natural fit.  We use TX to do XML <-> Cobol Copy Book which works pretty nice and we could also do that with Contivo when we looked at it.
