Use the node name if it is set, rather than the host name to construct Uid -------------------------------------------------------------------------- Key: JBTM-1337 URL: https://issues.jboss.org/browse/JBTM-1337 Project: JBoss Transaction Manager Issue Type: Enhancement Security Level: Public(Everyone can see) Components: Transaction Core Reporter: Tom Jenkinson Assignee: Tom Jenkinson Priority: Minor Node name is going to give us guaranteed uniqueness for transaction managers, we could use node name instead of hostname and pid. Uid is generic, xa node name is part of XA, but they are both in ArjunaCore/arjuna/ so it should not pose any dependency issues.
