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™.

Modify a C UDR

When the database server shuts down, it releases all memory that it has reserved, including memory for shared-object modules.

To unload a shared-object module from memory without restarting the database server, you must drop all routines that the shared library contains. Use the SQL DROP ROUTINE, DROP FUNCTION, or DROP PROCEDURE statement to unregister a UDR. These statements remove the registration information about the UDR from the system catalog tables.
