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 DataBlade® Developers Kit (DBDK) tools to develop and package DataBlade® modules.
Programming DataBlade® module routines in CThis section contains information to help you edit and compile C language source code generated by DataBlade®.
Compile DataBlade® module codeThis section describes how to compile DataBlade® module code.
Compile with tracing supportBy default, DataBlade® modules are compiled without tracing support.

Compile with tracing support

By default, DataBlade® modules are compiled without tracing support.

To compile with tracing, you must have generated source code in BladeSmith with tracing. BladeSmith adds the DBDK_TRACE macros and the TraceSet_project() procedure to your code if the Tracing property of the Source folder is set to True in BladeSmith Generate DataBlade dialog box.

After you compile with tracing, you must enable tracing for the DataBlade module after you register it in a database.You must also enable tracing in the database session.
