I have the below two alias queues targeting to the same local queue, I want to know the difference between the two
dis qa(AliasQ1)
TYPE(QALIAS) QSGDISP(QMGR)
CLUSTER(clus1) CLUSNL()
TARGTYPE(QUEUE)
PUT(ENABLED) DEFPRTY(0)
DEFPSIST(YES) GET(ENABLED)
DEFREADA(NO) DEFPRESP(SYNC)
TARGET(QLocal1) PROPCTL(COMPAT)
DEFBIND(NOTFIXED) CLWLRANK(0)
CLWLPRTY(0) CUSTOM()
dis qa(AliasQ2)
TYPE(QALIAS) QSGDISP(QMGR)
CLUSTER() CLUSNL()
TARGTYPE(QUEUE)
PUT(ENABLED) DEFPRTY(0)
DEFPSIST(YES) GET(ENABLED)
DEFREADA(NO) DEFPRESP(SYNC)
TARGET(QLocal1) PROPCTL(COMPAT)
DEFBIND(NOTFIXED) CLWLRANK(0)
CLWLPRTY(0) CUSTOM()
thanks |

Hi
the first alias is defined as a cluster one, so all the qmanagers in the cluster clus1 are aware of it .
The second is a normal qalias so it is know only to the qmanager where is defined...
You will find al lot more information on the proper manuals given by IBM . |

Thank you.
So if a job puts 10 messages to the first aliasq, they will be load balanced to all qmgrs in the cluster.
but the msgs put to the 2nd aliasq will be directing only to it's localq ?? |

Possibly.
There are numerous posts there about the sometimes thorny and non obvious topic of
BIND ON OPEN
https://www.ibm.com/support/knowledgecenter/SSFKSJ_7.5.0/com.ibm.mq.dev.doc/q027030_.htm
Without looking at the documentation I can't say for certain what would happen but if the open is done with MQOO_BIND_ON_OPEN then the messages may not be distributed around the cluster.
Do some research. All your answers are more than likely in the documentation.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

Also, messages aren't load balanced across queue managers.
They're load balanced across channels.
