Hi,

I've been trying to find some information but I can't find it.

I'm not 100% sure but I think I heard some months ago that the "newer versions of Powerserver WEB are no longer going to allow clients to run in a web browser and that everything is going to be run from some sort of IWA plugin"?

Is that correct?

If that is the case, I might be spending a lot of time on trying to get our applications to run in a web browser for nothing. By the end of next year we'll get powerbuilder "desktop on the cloud", so that would give us a "very" similar install for our customers? This "desktop on the cloud" isn't that exactly what we had in previous versions of powerbuilder based on winforms 2.0?

 

I'm a noob so please be patient with my ignorance.

regards,

Miguel

Hi Miguel;

   There are no planned changes to PowerServer to drop the Web Browser support. There are many, many Appeon customers (both in the government and private sector) that use PS Web for some of their mission critical applications.

Great, I don't know where I heard / read that then.

Good, so I'll keep trying to migrate our pfc heavy application to appeon web.

Maybe a good option to make it less heavy would be to combine it with the new datastore/datamodel 's on the server.

I'll surely give that a try too.

 

Thank!

Hi Miguel;



The PFC is supported by PowerServer as long as you are using a recent release of the PFC.



FWIW: The PFC is a "heavy" framework though. What could make a big difference performance wise in your Web & Mobile applications is to analyze your App's code to see where the various PFC services are instantiated. My suggestion (even to native PB App developers with the PFC) is to *not* instantiate the various services until your App *absolutely* sure that your App needs them in the transaction process flow. That should greatly reduce the massive PFC service overhead at Window start-up and/or DW Control construction. I have seen many times where PFC based App's instantiate 6+ services in the Window OPEN event or DW Control CONSTRUCTOR event (for each DC too) and only use 1-2 of those. That is a massive hit to the App's performance which can greatly burden a Web or Mobile app's responsiveness to the App user..



Food for thought

I once before tried to migrate our pfc app to web, using some pretty old pfc's. Last year I used also one of the later versions of pfc and that was immensely incompatible with appeon web. (Now I'm using the latest version).There might be good improvements, but there's a lot of data type / object types not being recognized by Appeon web and being used in the newer pfc's.



Good advice though on trying not to pre-load all the services to improve performance. Maybe it's also a good idea to start overriding the constructors of the pfc's themselves, as in lots of them there already have been instantiated a lot of services which now we turn off in the pfe, but without doing overrides.

Any way, my mission first of all, is to try and get everything we do working (ActiveX, Crystal Reports, Email with Outook, RTE control (yeah that one will wait a month :) ). After that the company I work for will make a decision and I'll start optimizing and improving.

Hi Miguel;

     What Armeen is talking about in his reply could (and I highlight the word "could") and/or might replace the IWA feature (just my guess) some day. However, that is to be seen once we see what exactly the C# Desktop Cloud feature entails.

      IWA's Forté is its ability to take any PB App (basically "as is") and deliver it dynamically deliver it to the desktop from a central server. Whereas the C# Desktop Cloud apps would be a complete PB App re-write into C# vs using PowerScript. Maybe better suited then for new applications (again - just my personal $0.02 at this point-in-time).

Regards ... Chris

Okay, I've watched the "key" videos of the Elevate 2018 and my question has not been aswered yet:

Will Appeon WEB keep running in a Web browser in the Future? (ie that functionality won't be replaced with the IWA)?

 

Cheers

by the way, I just found this similar question here https://community.appeon.com/index.php/qna/q-a/future-webassembly-deployment-instead-of-appeon-plugin

I'll have a look at the keynotes :)
