Hello,

We are using PowerBuilder 2019 R3 and trying to deploy on Power Server.

We have few questions

  1. Can multiple developers can access the same deployment and resolve issues? If so how can we achieve it?
  2. I am getting zlib.dll error when launching the application, even after adding the dll's under Deploy .NET/COM Components. How do we solve this?
  3. DB connection issue even after providing application configuration INI file during deployment.

Appreciate if we can get some guidance for the above issues.

 

Thanks in Advance

 

Regards,

Harish Rao

Hello Chris,

Thanks for a quick response, my responses below each 

 

1) Yes, you can install one PowerServer on a separate IIS machine and then two or more developers can deploy & run from the one instance. However, remember that a "developer" PS only allows a maximum of 5 connections.

[Harish]-- How to access the same deployment settings from 2 developer machines? Will power server handle conflicts when 2 developers deploy at the same time?

2) Any Win32 DLL following the standard PB external function declaration must be deployed along with the application and will be downloaded in the client "Appeon Cache Dir" when the application starts.

[Harish]---I did include the library its "zlib.dll" under the additional files. Still I am getting the error about the zlib.dll.

3) Remember that a PS based App does connect to the DB. Instead, PS does that for you based on the DataSource to Transaction Object mapping in the App Profile.

[Harish]---I have provided the setting under the DB settings under App profile. We are using SQL Anywhere DB and the test connection works file on the configuration page. Still I believe its not connecting to DB.

Regards,

Harish Rao

1) That would cause a deployment clash but, the chances of that are very low.

2) You can only deploy .Net object classes within the ".Net / OCX" area.

3) The test connection in the App profile only tests the PS Toolkit's DB connection. This is only used for SQL validation. The key is the SQLCA to DataSource mapping.

Hi Chris,

I have set the SQLCA in the datasource mapping and it tests successfully there.

Hi Harish;

That is only so the PS Toolkit can verify your SQL as it runs through the deployment process. The other thing to check as well before running the Web App is to make sure that you log into PS using AEM (PS's Console App) and verify that the DataSource you mapped to is working OK by selecting the TEST button.

Hi Harish,

Your questions indicates to me that you don't have a basic understanding of PowerServer.  You won't succeed without a basic understanding.  I recommend you first go through the PowerServer training course: https://www.appeon.com/appeon-u/pswf

With that said, a beta version of PowerServer 2021 will be released next month.  It basically supports 100% of PowerBuilder features and has much better architecture than PowerServer 2020.  So if your PowerServer project is not already almost finished, I recommend you start with PowerServer 2021.  

Best regards,
Armeen
