i am a newbie..
can any body help with with retreiving messages form a cluster queue..
My cluster configuration is as follows..
my machine
queue manager QM2
no local queues
remote machine
queue manager QM1
local queue myLocal
myLocal is shared in the cluster consisting of QM1 and QM2
my client application connects to QM2 and successfulty pust a message to myLocal
however when i connect my application ot QM2 to get the messages from 'myLocal' it gives me the following error
Unable to load message catalog - mqji
com.ibm.mq.MQException: Completion Code 2, Reason 2085
i am trying the following openoptions in order to open the cluster queue for retriving messages
| Code: |
| int openOptions = MQC.MQOO_OUTPUT|MQC.MQOO_INPUT_EXCLUSIVE; |
is there some problem with specifying hte open options or is it that we can read frm culster queues only by connecting to queue managers where they are defined?
pls help
thanking you all in advance.. |

Clustering does not allow you to do 'remote' gets from 'local' queues.
If you want to GET from myLocal, you have to connect to QM1.
This is true of everything in MQSeries. You can only GET from local queues. Well, okay, MQSeries Everyplace lets you do remote gets.

You can ONLY PUT to a cluster queue that is not locally hosted. To get, you MUST have a local instance of the queue to the queue manager you are connected to.
So, in your case, either you connect to QM1 and do the get, or define another instance of the cluster queue on QM2 and get from that.
Bear in mind, depending upon how you bind while putting your messages, they could either end up only in any one of the queues or could be load balanced.
