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.
MQ Messaging (WMQ) messaging products provide an infrastructure for distributed, asynchronous communication of data in a distributed, heterogeneous environment. The WMQ message queue allows you to easily exchange information across platforms.
MQ messaging configuration parametersWhen you use MQ messaging over a network, you must set several database server configuration parameters,
MQCHLTAB configuration parameterUse the MQCHLTAB configuration parameter to specify the name of the client channel definition table.

MQCHLTAB configuration parameter

Use the MQCHLTAB configuration parameter to specify the name of the client channel definition table.

onconfig.std value: none
range of values: String for the file name
takes effect: When the database server is stopped and restarted

Usage

You must set this configuration parameter when you use MQ messaging over a network. The configuration parameter contains the same information as the same as the (WMQ) MQCHLTAB environment variable.

The default file name in the WMQ MQCHLTAB environment variable is AMQCLCHL.TAB.

For example, if the name of the client channel definition table that you are using is CCD1, specify:

MQCHLTAB CCD1.TAB
