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.
Debugging and testing DataBlade® modules on UNIX™This section describes how to debug and perform functional tests for DataBlade® modules written in C for HCL OneDB™ on UNIX™.
Install and register DataBlade® modulesInstalling a DataBlade® module places the files of the module in a subdirectory of the $ONEDB_HOME/extend directory; registering a DataBlade® module adds the module to a database. You must install and register before you can test or debug a DataBlade® module.
Installing a DataBlade® moduleTo install a DataBlade® module for testing and debugging, create a project directory and copy the necessary files to it. Create the project directory under $ONEDB_HOME/extend. The name of the project directory is what BladeManager uses as the DataBlade® module name.

Installing a DataBlade module

To install a DataBlade® module for testing and debugging, create a project directory and copy the necessary files to it. Create the project directory under $ONEDB_HOME/extend. The name of the project directory is what BladeManager uses as the DataBlade module name.

About this task

A good project naming strategy is to combine the project name and version numbers you entered in the New Project wizard in BladeSmith. For example, the Circle project, Version 1.0, can be in $ONEDB_HOME/extend/Circle.1.0. HCL OneDB™ DataBlade modules also include a string indicating the build platform and minor release: for example, 1.0.UC1.TC2, where UC1 is the first UNIX™ major release, and TC2 is the second Windows™ minor release.

To copy the necessary files to the project directory, use one of these methods:

Procedure

Use BladePack to create an installation directory for your DataBlade module and then copy that directory into the module subdirectory under $ONEDB_HOME/extend.
Copy the project.bld file and the contents of the scripts directory into the project directory.
