Configure a JMS Connection

The JMS Connection is configured by adding a JMS Connection configuration JSON file in the estar/tpe/dynamic/mc2/eaglejms/connections folder. The samples below show how to configure the JMS connections to ActiveMQ and WebSphere MQ servers. For a more detailed description see #JMS Messaging.

...

1. If there is no ActiveMQ connection already configured, add a new file estar/tpe/dynamic/mc2/eaglejms/connections/extract_jms_connection.json with the following content:
   
   

   Code Block
   language js theme DJango title Sample ActiveMQ Configuration collapse true
   { "Region": "oraclesid", /*Database name (Oracle SID) on which the Extract Service is running */ "Connections": [ { "ConnectionName": "extract.jms.connection", "ComponentName": "amq", "Parameters": { "brokerURL": "tcp://activemqhostname:activemqport" } } ] }

   
   

2. Change the Region parameter to match the oracle SID the Eagle Extract Service is running with.
3. Change the brokerURL with the specific ActiveMQ instance parameters. The ActiveMQ hostname and port number should be provided by the ActiveMQ broker administrators.
