Hello,
I need to delete some of the shared queues. Before deleting the shared queues, i need to remove the queue from the cluster. I know how to do that on Unix. But this is the first time doing it on mainframes. I dont want to do any mistake. Please help me.
Thanks. |

You alter the queue object, and change the shared attribute to indicate that it no longer shared. Refer to the InfoCenter or MQSC manual.
You remove an object from the cluster on WMQ for z/OS in exactly the same way as you would do it on UNIX. Refer to the InfoCenter or MQSC manual.

On UNIX, we will just alter the queue by giving blank or none in the cluster field. But here "CF Structure Name" is this the thing i need to change to none. |

Your original post said you were going to delete the shared queue objects, yes?
If so, take the queue out of the cluster, then delete the queue definition.

The OP doesn't mean "cluster" - he's talking shared queues on a mainframe. a QSG

I read the OP as the queue was both in a cluster and a QSG.
Silly me.

That's correct. But what my question is that how can i take out the shared queue from the cluster. |

The queue is the shared queue. I have an alias queue that points to this shared queue. I need to remove them from cluster and then delete them. Please tell me the process.
Thanks. |

The process to alter the clustered status of an MQ object does not change if that MQ object is a zOS shared queue.
You might, however, need to alter *all* of the shared queue instances. |

Jeff. Are you saying that you cannot (effectively) alter the CLUSTER/CLUSNL attributes of an object that is part of a QSG? I don't have a system to test this out, but I recall doing this exact thing on v6 qmgrs - taking a queue definition out of a cluster, while leaving the queue def in the QSG.
WMQ clusters and QSGs are different, but can be used together.
This from the WMQ Queue Manager Clusters manual:
| Quote: |
A cluster queue can be a queue that is shared by members of a
queue-sharing group in WebSphere MQ for z/OS. |

No.
That's not what I'm saying at all.
?
I'm saying that you do the exact same thing to add or remove a queue from an MQ Cluster, regardless of whether or not it is a shared queue in a QSG.
And that if you have added all instances of a shared queue in a QSG to the cluster, then you need to remove all instances from the cluster as well. |

Very much what you've outlined above

Same way you add it to a QSG, but in reverse. Again you've indicated as much above.
Queue administration doesn't vary between z/OS & distributed. There are just some concepts (like QSG and storage class) that are specific to z/OS.

Do you have any experience with WMQ on any platform?
If not, have your management enroll you in a WMQ System Administration course. WM30 is a 4-day, hands-on, lecture/lab course that will give you the fundamentals of WMQ admin on z/OS qmgrs.
The WMQ Script Command Reference (MQSC) manual describes how to define, alter and delete, objects. A few of the attributes of objects are unique to z/OS WMQ, and are well documented.
To take an object definition out of a cluster, alter the object definition to set the cluster attribute to blanks, like this: CLUSTER(' ')
To take an object definition out of a QSG, alter the object definition to name the QDISP(SHARED) attribute, like this: QDISP(QMGR).
To delete the object definition from the qmgr(s) that owns the object, use the DELETE command, naming the queue to be deleted.

Thanks for the info. But i tried to change QDISP(SHARED) to QDISP(QMGR) from ISPF panel and from Appwatch. Its not allowing me to do so. The option looks disabled to me. |
