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™.
HCL OneDB™ extensions and DataBlade® modulesThese topics describe how to use built-in database extensions and separately installed DataBlade® modules.
Database Extensions User's GuideThe HCL OneDB™ Database Extensions User's Guide explains how to use the database extensions that come with HCL OneDB™: Large Object Locator, MQ messaging, binary data types, basic text search, node data type, HCL OneDB™ web feature service for Geospatial Data, and SQL packages.
Large object managementThe Large Object Locator extension enables you to create a single consistent interface to large objects. It extends the concept of large objects to include data stored outside the database.

API library

API library

All Large Object Locator functions except the smart large object functions are implemented as API functions defined in header and library files (lldsapi.h and lldsapi.a).

You can call the Large Object Locator API functions from your own user-defined routines. You execute Large Object Locator API functions just as you do functions provided by the HCL® OneDB® DataBlade® API. See the HCL OneDB DataBlade API Programmer's Guide for more information.

See The API interface for an example of a user-defined routine that calls Large Object Locator API functions to copy part of a large object to another large object.
