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.
SQL Packages ExtensionThe SQL packages extension provides SPL routines that you can use in an application that is compatible with database servers other than HCL OneDB™.
DBMS_OUTPUT packageThe DBMS_OUTPUT package provides a set of procedures for putting messages (lines of text) in a message buffer and getting messages from the message buffer. These procedures are useful during application debugging when you need to write messages to standard output.
ENABLE procedure The ENABLE procedure enables the message buffer. During a single session, applications can put messages in the message buffer and get messages from the message buffer.

ENABLE procedure

The ENABLE procedure enables the message buffer. During a single session, applications can put messages in the message buffer and get messages from the message buffer.

Syntax

Procedure parameters

buffer_size: An input argument of type INTEGER that specifies the maximum length of the message buffer in bytes. If you specify a value of less than 2000 for buffer_size, the buffer size is set to 2000. If the value is NULL, then the default buffer size is 20000.
