Release 10.1A: OpenEdge Development:
Messaging and ESB

Creating a JMS session

These are the general steps to create a JMS session in the 4GL:

Run jms/jmssession.p, jms/pubsubsession.p or jms/ptpsession.p persistently with the OpenEdge Adapter for SonicMQ connection parameters as INPUT CHAR parameters.
(Optional) Set JMS attributes and parameters by calling internal procedures in the session procedure.
Start the actual JMS connection and session by calling the beginSession procedure.
Note: Session attributes cannot be modified after calling the beginSession procedure.

Creating multiple sessions

A 4GL application can create and connect to multiple Session objects concurrently. You must create separate sessions to connect to each domain (PTP or Pub/Sub) with a separate SonicMQ Broker or a single SonicMQ Broker’s unified domain.

Note: It is recommended that you use the JMS session domain and minimize the number of Session objects. Each session represents a separate SonicMQ client session and you want to minimize the number of SonicMQ client sessions.
