I am reading "MQ v7 queue manager clusters, csqzah09.pdf" ...
Page 64 (copy and paste):
| Quote: |
| Use the SUSPEND QMGR command to remove a queue manager from a cluster temporarily, for example for maintenance |
One page later (pg 65) I read (C&P again)
| Quote: |
| Use the RESET CLUSTER command to forcibly remove a queue manager from a cluster |
My question is : what are the differences between those 2 commands ?
I see (correct me if I'm wrong)
a) SUSPEND is issued in the "target" queue manager
while RESET is issued from a Full Repository of the cluster
b) SUSPEND does not have the "forcibly" adjective, while RESET does have it, but I dont know what it means ... Maybe "SUSPEND" can fail and "RESET" does not ? Never never ??
And if it not too much to ask, I am also having doubts on the diferences between RESUME (after SUSPEND) and REFRESH (after RESET) ...
Any specific diferences ?
Thanks. Sebastian. |

RESET is used to forcibly remove the information from the Full repository.
SUSPEND leaves the information in the Full repository intact and merely signals that you do no longer want to be included in the load balancing.
The same way:
REFRESH checks the information in the FR and tries to add you if you are not there.
RESUME tells the FR that you a ready to rejoin the load balancing.
Beyond that  the cluster manual a bit more...

mr Saper - the indication to keep on reading is always welcome,
But I'd say you have to agree that manual is not very clear in some BASIC points, as by example, on specifying on which queue manager of the cluster do you issue a specific command ...
Thanks for the resume.
It is always good to have a simple line with a clear message.
Sebastian. |
