Can anybody help me ???
When started to use MQ Series it were running on a single machine with W2K to transfer messages between the website and the central system and vice-versa. Due to the criticism of this service it were decided to implement a cluster so it has been decided to go ahead with MQ running on a W2K cluster system. The application had been installed on top of this cluster and it seemed to work out fine during several months. Meanwhile new queues and channels were defined on top of this new solution and everything looks fine but it weren't. When using the new queues and channels on machine 2 there were no problems at all, but every time the cluster changes to machine 1 we started to find the first problems. Those new queues, when on machine 1, do the normal processing accepting PUT instructions going through the right channels and returning back right to the appropriate queue where it was expected to GET the message. The problem is that when GET is issued it doesn't return the message so the system response is a timed out operation. I traced the whole path of the message and there is no MQ error. The message is received by the right queue goes to the central system pick up the right return message and deliver it to the right queue, and as it is a no persistent message after 15 seconds it is gone from the return queue and not delivered. Tracing inside MQ returns no errors, the website code used does not invoke the machine name but the cluster name and I can't find were the problem is.
