No it doesn't

that is why it does not put a MQOO_OUTPUT call.


It does do an open inside the call, followed by a close.

All of this is thoroughly and succinctly documented in the WMQ APR manual (and InfoCenter equivalent).

@Vitor
I wasn't aware MQOO_OUTPUT is opened and closed in the MQPUT1 call (Didn't find it in InfoCenter)

I know that under clustering, MQPUT1 assumes MQOO_BIND_NOT_FIXED is true in the MQOPEN call and it then invokes the Workload algorithm.

My topic for discussion at a work seminar is Clustering and MQOPEN Calls.
If you could provide a pointer to any article/whitepaper on MQOPEN calls, it would greatly aid my research.

Thanks

@Bruce point noted.

MQOO_OUTPUT is an option, not a handle that can be opened or closed.

You know wrong. You can specify any open option in the MQPUT1 call including the clustering one. MQPUT1 doesn't "assume" bind not fixed any more than MQPUT "assumes" bind not fixed because the application doesn't know it's putting to a clustered queue!!!. Binding options are explicitly specified or allowed to default to the queue values.

Well you certainly seem to have a lot of knowledge on the subject.

Look in the InfoCenter and on devworks.

No. It is clear that you do not know how to research. The MQPUT1 call is well-documented as to how and what it does, and what it does not.

Research involves search. I will provide you with a pointer on how to begin your search.

Go to google, or your favorite search engine. Type keywords in the text box. Click the search button. Read the results. Re-read, if necessary.

We take no joy from this.

Learning is a process that demands discipline. There is no easy way. There is joy in learning. There is satisfaction in doing the work.

Quite often I have not posted a reply because I wasn't 100% sure of the facts or the correct response. If in doubt, leave it to others, rather than put foot in mouth.
