What are the options to migrate a web Power Builder application from EAServer to IIS

Hi all,

We migrated to IIS an EAServer application with PB 12.6. To migrate, we generated SOAP web services from our NVOs.

It is up and running since last year and it is consumed by a web site app we wrote in Java.

Everything works as expected as far as business model but the response time is to high: it is more then double the time when compared with EAServer response time.

We believe the culprit is NOT the parsing logic (from XML), but the page load time the browsers take to display the page to the Users.

Our conclusion is that the SOAP protocol is too expensive, consumes too much time.

Our questions are:

1. How to improve the SOAP performance?

Do you know any other Company from SAP Customers that have done the migration from EAServer to IIS ?

2. Any workaround besides the use of SOAP web services?

3. Is there any other alternative?

What about generate .Net Assemblies from the NVOs and call them from the Java front-end ?

Do you know any of your Customers that have done the migration this way?

All suggestions are welcome.

Thank you,

    Hi Paulo;

    I know that the Intertech group out of Texas has done a lot of work in EAServer to IIS migrations. You may want to touch base with them and see what recommendations they might have. The person I talk with quite often there is Mr Don Clayton.
