Extending HCL OneDB™Beyond standard relational database objects, HCL OneDB™ can be extended to handle specialized data types, access methods, routines, and other objects. HCL OneDB™ includes many built-in extensions that are fully integrated in the database server. HCL OneDB™ also provides DataBlade® modules, which are packages of extended database objects for a particular purpose and that are installed separately from the database server. Alternatively, you can create your own user-defined objects for HCL OneDB™.
Creating extensionsYou can create user-defined data types, routines, access methods, and other database objects to suit your needs. You can use application programming interfaces to write user-defined routines and applications that access data in HCL OneDB™ databases.
DataBlade® Developers KitThe DataBlade® Developers Kit (DBDK) guides contain information about the tools you can use to develop and package DataBlade® modules, which extend the functionality of HCL OneDB™ databases.
DataBlade® Developers Kit User's GuideThe HCL OneDB™ DataBlade® Developers Kit Users Guide describes how to use OneDB® DataBlade® Developers Kit (DBDK) tools to develop and package DataBlade® modules.
Create ActiveX value objectsThis section describes how to use the OneDB® DataBlade® Developers Kit (DBDK) to create ActiveX value objects. This section describes the use of C++ to implement opaque type support routines.

Compiling a Windows™ server project

Compiling a Windows server project

About this task

For Windows™ server projects, BladeSmith generates a Project.dsw file in the src directory to use with Microsoft™ Visual C++ 6.0.

To compile a server project, the INFORMIXDIR environment variable must be set to the HCL OneDB™ server installation directory.

Because BladeSmith does not generate tracing routines in the source code, projects are not built with tracing support. If you have added DataBlade® API tracing routines to your code, you must add the instruction to compile with tracing support to your makefile or project file. For more information, see Tracing and error handling.

To compile a Windows server project:

Procedure

If necessary, open your project.dsw file in the src directory in Visual C++.
Choose Build > Set Active Configuration.
Select a version of the project in the Set Active Project Configuration dialog box:
- Release. This version is suitable for release and does not contain debugging support.
- Debug. This version contains support for debugging.
Click OK.
Choose Build > Rebuild All to compile.

Results

Visual C++ creates a WinNT-i386 directory to hold the release version and a Debug directory to hold the debug version under the src\ActiveX of the dynamic link library.
