A broker, in PUB/SUB can be:
A QMGR in MQ
A Broker in Message Broker or Event Broker (I don't know much about Event Broker, so I might be wrong).
If MQ is the pub sub broker, the broker commands are :
dspmqbrk
strmqbrk
endmqbrk
| Code: |
C:\Documents and Settings\admin>dspmqbrk -m QM1
WebSphere MQ Publish/Subscribe broker for queue manager QM1 not active.
C:\Documents and Settings\admin>strmqbrk -m QM1
WebSphere MQ Publish/Subscribe broker started for queue manager QM1.
C:\Documents and Settings\admin>endmqbrk -m QM1
WebSphere MQ Publish/Subscribe broker for queue manager QM1 ended.
C:\Documents and Settings\admin> |

Because, you always don't use it I guess
I deleted your other post because I thought it is the same question.
Point to Point is you send a message from one destination to another destination.
Pub Sub is you publish a message on a topic and multiple subscribers can subscribe to the topic and get the messages published by any publisher. |
