Extending Informix®Beyond standard relational database objects, HCL Informix® can be extended to handle specialized data types, access methods, routines, and other objects. Informix® includes many built-in extensions that are fully integrated in the database server. Informix® 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 Informix®.
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 Informix® 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 Informix® databases.
DataBlade® Developers Kit User's GuideThe HCL Informix® DataBlade® Developers Kit User's Guide describes how to use tools to develop and package DataBlade® modules.
Debugging and testing DataBlade® modules on Windows™This section describes how to debug and perform functional tests for DataBlade® modules written in C and C++ for Informix® on Windows™.

Prepare your environment

Test and debug your DataBlade® module in a nonproduction HCL Informix® database server environment because debugging interferes with the operation of the database server.

To use the debugging features of the DBDK Visual C++ Add-In, you must have a local database server.

Before you begin testing and debugging your DataBlade module, verify that your database server is running properly. Use the Setnet32 utility to complete the Server Information page and create a default database server. Create a database with SQL Editor; if the command succeeds, your server is properly configured and the DBDK Visual C++ Add-In works properly.

See the Informix Administrator's Guide for more information about configuring your HCL Informix database server.
