Summary: Define a new broker plugin to track XA transactions
Key: ARTEMIS-2855
URL: https://issues.apache.org/jira/browse/ARTEMIS-2855
Project: ActiveMQ Artemis
Issue Type: Improvement
Reporter: Domenico Francesco Bruscino
Assignee: Domenico Francesco Bruscino
The broker is frequently used in transactions from the Wildfly/EAP app server,
acting as an XAResource manager to the app server's Transaction Manager. In
distributed environments, multiple app server instances can be communicating to
the same broker.
It is common for these app servers to be incorrectly configured, using a shared
default nodeId, when this value is required to be unique for safe operation.
App server instances don't necessarily communicate peer to peer, so can't
detect this situation. The broker, however, sees nodeId values from all its app
server clients, so can detect this.
Defining a new broker plugin interface to track XA transactions would allow to
implement an external plugin to detect the XA client misconfiguration.
