IBM MQ documentation says:
"If an application disconnects (MQDISC) from a queue manager while a global unit of work coordinated by IBM® MQ is still active, an attempt is made to commit the unit of work. If, however, the application terminates without disconnecting, the unit of work is rolled back as the application is deemed to have terminated abnormally."
The case of application issuing a MQDISC is clear. My doubt is about the second scenario: let's say I'm putting messages and the applicative servers suddenly loss power before the commit. How does the rollback work if the application is not available at all? Would those message end in the DLQ, or...?
