Web materials will be available when the Redbook is published, not in the draft version

In chapter 4 on page 35, it says "A queue manager has at most one DLQ.", which was true before V7.1 (as explained on page 61 and chapter 9.)

And a qmgr still has at most one DLQ. The change in V7.1 makes it more selectable on whether or not it is used by different channels. There is no option to use a different DLQ.

Congratulations (and thanks) to the team for an excellent Redbook! A pleasure to read.

Just noticed this on page 54 of the draft (under "How to start communication automatically"):

"To have the transmission queue triggered, add three more parameters (below shown in bold):
DEFINE QLOCAL(QMB) REPLACE +
USAGE(xmitq) +
TRIGGER
TRIGTYPE(first) +
INITQ(SYSTEM.CHANNEL.INITQ)"

I believe you also need TRIGDATA(sender channel name).

Happy New Year,
Emir

Thanks for the comment Emir. Actually, TRIGDATA is only required on z/OS - it's been optional on other platforms for a very long time (V5.0 I think). Having the channel not specified in the queue definition gives additional flexibility, for example if you have multiple channels defined against the same xmitq for backup purposes (though explaining how that is done is way beyond the scope of a basic introduction).

We will get the z/OS difference mentioned.

Mark.

There's no epub edition of this book, so it would be very nice if you publish it in this popular format. Thank you.

Hi Igor,
Thanks for you feedback. This book is not formally published yet (still in draft). It will be available in ePUB format when published.
