4.1About the Database OTD Wizard

The Database OTD Wizard generates OTDs by connecting to external data sources and creating corresponding Object Type Definitions. The OTD Wizard can create OTDs based on any combination of Tables, Stored Procedures, or Prepared Statements.

Field nodes are added to the OTD based on the Tables in the external data source. Java method and parameter nodes are added to provide the appropriate JDBC functionality. For more information about the Java methods, refer to your JDBC developer’s reference.

The OTD Wizard allows the addition and removal of columns/nodes in an OTD. Nodes with the same name and type as existing nodes are allowed by the Wizard, but should not be created, and will result in generic code generation errors upon activation of the OTD.

Note: Database OTDs are not messagable. For more information on messagable OTDs, see the eGate Integrator User’s Guide.

4.2Creating a New VSAM OTD

The following steps are required to create a new OTD for the VSAM adapter.
