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.
User-Defined Routines and Data Types Developer's GuideThe HCL OneDB™ User-Defined Routines and Data Types Developer's Guide describes how to define new data types and enable user-defined routines (UDRs) to extend HCL OneDB™.

Perform bulk copies

Perform bulk copies

The database server can copy data in and out of a database with a bulk copy operation. In a bulk copy, the database server sends large numbers of column values in a copy file, rather than copying each column value individually. For large amounts of data, bulk copying is far more efficient than moving values individually.

The following HCL OneDB™ utilities can perform bulk copies:

DB-Access performs bulk copies with the LOAD and UNLOAD statements.
The dbimport and dbexport utilities perform bulk copies.
The High Performance Loader (HPL) performs bulk copies.
The pload utility loads and unloads a database from external files.

The database server can perform bulk copies on binary (internal) or character (external) representations of opaque-type data.
