WMB is only one of several choices.
The InfoCentre says that subscription based on content filtering requires the use of an "extended message selection provider".
It could be one of several options.
So the answer to the OP's questions is "No", use of WMB is not required.

I invite you to provide the name of any other choice that exists, is known to work, and is supported in this function by anyone. |

A shell script with GREP works, a custom written C program works, a VB or .Net program works.
All are supported in the same way WMB would be (ie. IBM does not support customer written code).
If IBM meant "WMB" in this statement: "extended message selection provider"; they would have said "WMB" rather than "extended message selection provider". IBM documentation usually says what it means and when it is vague like "extended message selection provider" its vague for a reason.

These are all things that *can be written*.
This is not remotely the same as 'exists'. |

Neither does WMB automatically filter results. You have to write the filter logic.

Perhaps you could be clearer on your perception of the reason?
It's also only a vague as the OP's question; following your reasoning it's not a must to use WMQv7.5 for publish / subscribe. You'd struggle to implement with a grep script, but you could write code in either C or .NET that acted as a publish / subscribe broker. So it's not a must to use the IBM product.

If we extend the arguement along the lines you indicate, then IBM's Business Process Manager is equivalent to C or .NET as you have to write the rules logic, and that would be a serious bit of code if you tried that in C or .NET!

The OP is not asking which tool is the easiest to use. The OP asks "Is it must to use Message Broker for content filtering in publisher/Subscriber in IBM WMQ 7.5?" The correct answer is "No", there are several tools available with differing levels of convenience.

Which I agree is the pedantically correct answer to almost every question of this type, since you can always write your own code to fill any requirement and provide any solution. So you have pedantically answered exactly the question the OP asked and are therefore the winner (which was your intention) while managing to utterly avoid the question the OP was trying to ask. Which is of course his fault for not being pedantically precisce in his wording.
Equally pedantically your answer should end:
"...differing levels of convenience, cost and vendor support."

No.
There are several tools available which can be used to BUILD a tool.
The only tool that *is available* is Broker.
There's a difference between owning an automobile and an automobile repair shop, when one wishes to travel along the highway. |
