Hi,
we use MQAI ti read the even queues. This works fine on nearly all machines for years. Lately I discovered a strange output, I found not exspected binary data.
This is the code I use:
| Code: |
mqInquireItemInfo(bag, selector , i, &outSelector, &type, &compCode, &reason);
...
switch (type)
{
...
case MQIT_STRING:
mqInquireString(bag, selector , i, 1023, buffer,
&length, NULL, &compCode, &reason);
...
mqTrim(length, buffer, buffer, &compCode, &reason);
printf("%s", buffer);
...
|
The output normally for AMQ9208 is:
hostname (ip-addr)
On one system the output is complete ore partially not printable.
Sometimes I see something like this
02
or
hostname (E1 15 83 7C 14 01)
The hex values sometimes destroy the output format, so there is no right parenthesis.
Is there a mistake in my code?
How do I avoid this nonprintable chars?
Thanks for any help.
Regards Gunter

This has to do with IPV6 / IPV4
Read up on the display of the IPV6 format and you will see that it looks something like that (from memory...so...) ff:fa:1f:3a:5b
Enjoy

We don't use IPV6 and the queuemanager is configured for IPV4.
Even with IPV6 I expect printable chars in a hex notation and not binary.
I checked the AMQERR01.LOG and there are also binaries in it.

AMQ9208: Fehler beim Empfangen von Host 'host (áƒ|è )'.
ERKLÄRUNG:
Beim Datenempfang von 'host (áƒ|è )' über 'TCP/IP' ist ein Fehler
aufgetreten. Dies ist möglicherweise auf einen Datenübertragungsfehler
zurückzuführen.
AKTION:
Der Rückkehrcode des Aufrufs 'TCP/IP (recv)' lautete '10054' (X'2746').
Notieren Sie diese Werte, und benachrichtigen Sie den Systemadministrator. |
Any idea how to get rid from it.
Regards Gunter

I would do what the message says and inform the System (or network) Administrator(s).

Looks like PMR time.
If you're sure it's not shared memory corruption...
