To my horror, I discovered that we can actually delete the messages while browsing the queue (in the application guide - Removing a message that you have browsed )
Why, I mean why any one wants to do that. I shouldnt go into a database table and delete the rows just because I can ! I understand the admins might need this feature, but it looks like I can actually write a small program to do this remotely.
Is there any special scenario in MQ where we need to do this.
p.s: I am sorry, if this is not the right forum to ask this.

Most people don't and you certainly shouldn't. The feature exists in the product for the same reason it allows you to set msg id; in 99.9% you shouldn't do it but in that 0.1% of cases there's no option.

No you shouldn't but you could.

No, not usually.

You can, in the same way you can write a small program to read the result set from a database with a cursor.

In the same circumstances you'd read a database with a cursor; i.e. almost never.
If you're worried about application developers doing this, either introduce QA on the code, or enforce the use of a user id that doesn't have browse permissions.
