For the first time to connect to the Informix database, you will need to install the corresponding .NET Core driver to the development PC. When you select Informix from the Provider list in the Database Configuration dialog box, you will be prompted to have PowerBuilder automatically download and install the driver or specify an existing driver on the development PC.
-
If you select to have PowerBuilder install the driver from www.nuget.org, it indicates that you agree with the license agreement. The driver will be automatically downloaded to your local path (%USERPROFILE%\.netdbdrives).
-
If the driver has already been downloaded from www.nuget.org to your computer, you can select The driver already exists locally and specify the location of the driver.
It must be the .NET Core driver (IBM.Data.DB2.Core 3.1.0.600) downloaded from www.nuget.org, otherwise installation will fail.
Note: the .NET Core driver for Informix (IBM.Data.DB2.Core 3.1.0.600) requires the Visual C++ Redistributable Packages for Visual Studio 2013 to run. If the Visual C++ Redistributable Packages for Visual Studio 2013 is not installed, you will be prompted when creating the database cache in the PowerBuilder IDE.
To resolve this error, you can download and install Visual C++ Redistributable Packages for Visual Studio 2013 from https://www.microsoft.com/en-us/download/confirmation.aspx?id=40784.
