The MC2 plugin enables you to define the format of streams for JMS components:
...
- MC events log - scope of information to print in MC log
- Sequential Reading - this option allows us make current Eagle JMS Stream as single JMS Consumer (single reader) across cluster.
- Acceptable values: Y/N or empty value means N
- Supported JMS destination types: QUEUE & TOPIC
- Durable Subscription Name - this option allows us enable Topic Durable Subscription mode for current Eagle JMS Stream. A durable subscriber is a message consumer that receives all messages published on a topic, including messages published while the subscriber is inactive. In short it means that we want to have many topic subscribers, but additionally add persistence for our messages.
Acceptable values: alphanumeric and undersore characters. Empty value means that option is disabled. This option can be enabled if and only if Destination Type parameter is TOPIC, otherwise you will get Sequential-Reading JMS Consumer for appropriate QUEUE.
...
For example, you can create a new connection for Durable Topic Subscription Stream connection.json, using eagle-amq-no-pool as the component name:
| Code Block |
|---|
{
"ConnectionName": "myactivemq3-tds.connection",
"ComponentName": "eagle-amq-no-pool",
"Parameters": {
"brokerURL": "tcp://inno-jenever03.eagleinvsys.com:61616"
}
} |
- JMS Connection User - it is login/user name which you have to provide to connect to JMS Broker if this one was set up to check user authorization.
- JMS Connection Password - the connection password.
- Consumer Selector - A JMS message selector allows the user to specify, by header field references and property references, the messages it is interested in. For more information refer to Message Selectors.
- Concurrent Consumers - you can specify the default number of concurrent consumers when consuming from JMS. Note: for ActiveMQ we should use the number of concurrent consumers calculated by this equation:
...
- URI parameters - extra parameters for fine-tuning JMS Consumer.
- To add some URI parameters of Camel JMS Component being described in Camel documentation, you have to construct a string that corresponds with following format of URI: parameterName1=value1¶meterName2=value2......
- RequestReply JMS Consumer pattern - to enable RequestReply JMS consumer behavior (sending the reply to the appropriate queue), you have to set replyTo URI parameter into URI parameters field of Stream properties and define the name of queue: replyTo=<destination name>.
