Interface DataAdapterMBean

public interface DataAdapterMBean

Multiple DataAdapterMBean instances are allowed in the system. Each DataAdapterMBean instance pertains to one Data Adapter instance. Each Data Adapter instance is bound to one DataAdapterMBean instances. Note that each Adapter Set may contain multiple Data Adapter instances. Each DataAdapterMBean instance is created at startup by Lightstreamer Server and lasts until the shutdown of the Server. Remote JMX clients should not deregister DataAdapterMBean instances.

DataAdapterMBean name pattern:
"com.lightstreamer:type=DataAdapter,AdapterSetName=<AdapterSetName>,DataAdapterName=<DataAdapterName>"

To ensure compatibility with old JMX clients as long as old adapters deployment style is used, Data Adapters whose local name is not configured (or whose local name is "DEFAULT") can also be addressed through the following pattern:
"com.lightstreamer:type=DataAdapter,name=<AdapterSetName>"
