Creating Data Source Dynamically

Overview

Data source can be predefined/modified/deleted in Appeon Server AEM (refer to the section called “Data Source” in Appeon Server Configuration Guide for .NET for details), or dynamically created/modified/deleted via appeondconfigdatasource object in Appeon Workarounds PBLs. But unlike creating data source in AEM, you could only dynamically create data source for the following database types: Microsoft SQL Server, Teradata, MySQL, SAP ASE, and PostgreSQL (data sources for Oracle, IBM Informix, SAP HANA, and SAP SQL Anywhere cannot be created via appeondconfigdatasource object; they can only be created in AEM).

Note that you can only call appeondconfigdatasource object to dynamically create data source on the Appeon Server for .NET version (not J2EE version).
