HI ,
I have two queries here related to publish/subscribe:
1)when i fire Reg Sub command from broker on system.control.queue it gives response back in pscr folder as ok or error. Now if i fire Reg Sub command in a loop (lets say 5 times for different topics) and one of the Reg Sub reponses back with error, then is there any way by which message broker or MQ can rollback other 4 subscriptions from MQ repository?
2)is there any way (via message broker) by which MQ repository can be queried/browsed to see how many subscriptions exist for per topic?
Thankyou! |

1. Yes, issue the corresponding reverse-posts to undo the subs.
2. Yes. Check out the SubscriptionParameters class.
