For each broker, WebSphere Message Broker maintains
a set of properties. You can access some of these properties from your ESQL
programs. A subset of the properties is also accessible from Java code. It
can be useful, during the runtime of your code, to have real-time access to
details of a specific node, flow, or broker.
There are four categories of broker properties:
- Those relating to a specific node
- Those relating to nodes in general
- Those relating to a message flow
- Those relating to the execution group
Broker properties that are accessible from ESQL and Java shows the broker, flow, and node properties
that are accessible from ESQL and indicates which properties are also accessible
from Java.
Broker properties:
- Are grouped by broker, execution group, flow, and node.
- Are case sensitive. Their names always start with an uppercase letter.
- Return NULL if they do not contain a value.
All nodes that allow user programs to edit ESQL support access to broker
properties. These are:
- Compute nodes
- Database nodes
- Filter nodes
- All derivatives of these nodes
