XA transaction failure with 3 involved servers

Solution In Progress - Updated -

Issue

  • Setup/ call sequence:
    • client invokes EJB A on server A,
    • on server A
      • Container on A starts tx,
      • EJB A updates record in database and
      • invokes remotely EJB B on server B
    • on server B
      • EJB B again invokes a datasource and
      • invokes EJB C on server C,
    • on server C
      • EJB C updates record in database.
  • During invocation/transaction in flight server B crashes and get restarted
  • as some tx-branches get committed while other get rolled-back the outcome is inconsistent.

Environment

  • JBoss Enterprise Application Platform [EAP] 6
