Paul,
Honestly I found the problem a few minutes before I noticed your ticket. I could not wait for the ticket, because I was too curious.
I changed the data queue monitor to replace non-displayable characters with a replacement character that you can specify on the iSphere "Monitors" preferences page.
I also added a preference value for specifying the maximum number of messages to retrieve. Last but not least I changed the "pin view" option to save the number of message to retrieve.
I assume that I can release a new beta version this evening.
Thomas.

That's great, Thomas, thanks. Was that before or after I created the sourceforge ticket?

Eventually I could recreate the problem. While the IBM character
converter class ignores non-displayable characters, such as x'00', the
Windows clipboard stops adding text at a x'00' character.
I am going to change my "retrieve message text" procedure to replace
characters that are a control character (Java: Character. isISOControl()).

Paul,
Can you please create a CL or RPG program, such as TSTDTAQ1.CLP, that
produces a data queue with entries to demonstrate the issue? I need
something to debug the problem. If that is not possible, then please
save such a data queue to a save file and send it to me or attach it
to an iSphere ticket at SourceForge. We are on 7.2.
Regards,
Thomas.

Betreff: Re: [WDSCI-L] iSphere data queue monitor
Thanks Thomas. I know about the double-click and that isn't working either.
Here are some specific details.
I find my (max length 1024) data queue in RSE, and right-click and
select iSphere Data Queue Monitor. The View appears and shows me 5 of 14 records.
I change the number of messages to 50 to show the hidden messages, but
this makes no difference to the problem.
The first and second entries are exactly 1024 characters long, with 4
characters at the start and 1020 spaces after. The data queue monitor
view tells me it is 1024 characters long. I double-click either and
the view shows the full text and 1024 hex digits (it tells me it is
showing 2048 hex digits, but that is 1024 bytes/characters).
The third entry is more complex. The view tells me that the entry is
752 characters long. Double-clicking that entry shows 128 hex digits,
and 64
characters:
"*PDFWTR 0101NC_EMAIL HOWARDP 597277CLMFRM" + 4 spaces (i.e. hex(40))
+ hex(000000000001) + 8 spaces
There should be another 242 spaces followed by more text (a path name)
then lots more spaces and finally a user name.
When I right-click a message and "copy as text" I get only 50
characters and nothing more. If I right-click and "copy as hex" I get
1024 characters (with the last 260+ being spaces).
I'm not sure how to best present this to you so that you can see the
problem. Any ideas?
-Paul.

I forgot to mention that you can also double click a message to openlimitation:
the "Data Queue Entry" viewer to display the whole message text.
From the viewer you can use the "Previous" and "Next" buttons to
move forth and back through the messages.

Hi Paul,
So far I could not exactly reproduce the bug. I used RDP 8.0 and RDi
9.5.0.3 and Windows 7 to debug the problem. For me the text is
truncated after the 259th character. That seems to be a known
Windows
up to the user?
https://bugs.eclipse.org/bugs/show_bug.cgi?id=259013
https://bugs.eclipse.org/bugs/show_bug.cgi?id=257815
Please open a monitor for your data queue. Then right-click a
truncated message and select "Copy message as text" or "Copy message
as hex". This way you should get the complete message data. Please
let me know if that is true for you.
What RDi and what operating system do you use to run your IDE?
Thomas.

Hi Paul,
It should be not a big deal to implement option a).
Your bug is under investigation. I will keep you updated regarding
to option a) and the bug.

Thomas.

Hi Thomas,
For (a) I'd point out that hexadecimal values are reasonably
familiar to a fair number of programmers on this list and so
entering packed decimals aren't totally strange, but maybe just a
simple editor that takes either Hex or Char and the data
formatting is
that?
I thought (b) might be too much. As you are passively reading the
data queue with the QMHRDQM API, you are not affecting the data
that could be processed by another program at any time and it
would be a shame to risk data damage by trying to be too clever.
After several weeks of playing with the data queue monitor, I have
only just found a bug! There is an option to display any data
queue entry (as both hex and char) but it *only* ever displays the
first
100 characters
(bytes?) of the entry. There is an option to change how much of
the data is displayed, but this appears to have no effect on the
display of data queues longer than 100 chars. (I was using one of
1024 chars in length.)
Thanks for your continuing hard work!
-Paul.

Hi Paul,
The data queue monitor uses the QMHRDQM API to read the messages
of a given data queue. Since the QMHRDQM API does not remove
messages from the queue, reposting of messages is not required.
Honestly I already thought about posting and deleting messages.
Here are my concerns about that:
a) I think that we can safely assume that people usually use data
structures to build the message data. So what shall we do when the
message data is composed of binary or packed values?
b) Removing messages from a data queue is not easy. As you already
pointed out, iSphere had to receive and repost the messages,
ignoring the messages to be removed. Can you think of a save way
to do
--Actually the plug-in cannot do that, because of network problem
that may happen all the time. Most likely iSphere had to use
commands to dump the queue to a physical file and to repost the
messages from the file. Both commands had to be called from a CL
program on the IBM i server. Just reading and reposting the
messages one by one is not save enough because of possible network
problems. Another option could be to create an empty "staging"
queue (save/restore and QCLRDTAQ,
problem: produce temporary name), then populate that queue with
the remaining messages and eventually rename that queue to the
original name. Another problem is that the messages that are
removed could only be identified by their index number, when the
whole thing runs on the IBM I server. Last but not least there had
to be an exclusive lock on the queue from the point when the user
selects the messages to the end of the job.
Everybody: What are your ideas for solving the problem?
Regards,
Thomas.

Betreff: [WDSCI-L] iSphere data queue monitor
Hi Thomas/Frank,
I've been playing with the data queue monitor recently and I like it.
I have a question, and a possible enhancement request.
Is the monitor displaying the data in the data queue passively, or
is it reading and reposting the data queue items?
Can we have a feature to enable posting and deleting items from a
data queue? The posting part should be fine, using the QSNDDTAQ
api, but removing an item might require removing all and reposting
the ones still required.
What do you think?
-Paul.
