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.
BladePackBladePack creates installation packages for DataBlade® modules and other software products.
Packaging for InstallShield 3.1 installationsTo package your DataBlade® module, you add content to a BladePack project, assign components, customize the installation procedure, and build the package.

Adding custom extensionsIn addition to adding the custom routines, dialog boxes, and programs in their respective folders, you must also add the file containing the custom extension to the Support Files folder. However, if you have more than one routine, dialog box, or program in a file, you need only add that file to the Support Files folder once.

Adding custom extensions

In addition to adding the custom routines, dialog boxes, and programs in their respective folders, you must also add the file containing the custom extension to the Support Files folder. However, if you have more than one routine, dialog box, or program in a file, you need only add that file to the Support Files folder once.

About this task

The following table lists the properties of custom routines, dialog boxes, and programs you specify when you add them to your installation project.

Table 1. Properties of custom routines, dialog boxes, and programs
Property	Description
Name	The file name of the routine, dialog box, or program. Type the name or click Browse to select the file in the Open dialog box.
ID or command-line arguments	For a custom routine, the ID string is an identifier you can use to determine which routine to call if you have more than one routine in a single DLL. For a custom dialog box, the resource ID that you specified when creating it in Microsoft™ Developer Studio. For a custom program, the command-line arguments you want to use for the program during the installation process.
Target operating system	The operating system on which the custom extension runs.
Component	The component, subcomponent, or shared component to which the file or directory is assigned. See Assigning items to components for more information about assigning to components.
When to run	When the custom extension is executed during the installation procedure: Before the installation program begins Before the project files are copied After the project files are copied Before the installation program exits
