MQ install on Linux kernel 2.6 or greater
Has anyone been able to get MQ to install and run on a Linux kernel 2.6 or greater?
If so, do you have any tips?
I'm aware of the issue with LinuxThreads and have set LD_ASSUME_KERNEL=2.4.19. But,
it still isn't working. I think that something is wrong with the install process (I'm
running on Debian Linux and had to convert the *.rpm packages to *.deb via alien).
If anybody could post their LinuX MQ directory structure, that would help me to see
how things should be getting installed. Just an ls -lA /var/mqm and ls -lA
/opt/mqm would be a great help.
Thanks!
I'm getting this message when I try to do a simple crtmqm -q QM1

Session.createProducer(null) throws MQJE001 Reason 2085
Does MQ support the creation of a MessageProducer with a null destination? I'm getting the error specified in the subject - with reason 2085. According to the JMS 1.1 Javadoc, I ought to be able to do this. Am I missing something?

Re: JMS MessageProducer very slow writing to Cluster Queue - Resolved
James,
Thanks. You are exactly right - I was using the same Session to send
messages while a consumer in that Session had registered a
MessageListener. A basic violation of Session single-threading. I
could have saved myself a lot of headaches by reading the JMS
specification!
For what its worth, I do think that having Websphere MQ detect this and
throw a runtime exeception would be a valuable application programming
aid. I assume it is a common mistake that JMS novices make.

Hi Mark,
It sounds like you may have been using the same Session
instance for the
MessageListener and the MessageProducer. This is technically
a violation
of the JMS specification (unless the MessageProducer is used
from within
onMessage) as it breaks the single threaded use of sessions. Some
versions of MQ JMS detect this case and throw an exception, but I
believe the latest version lets it through, in which case it would be
likely to suffer the sort of performance issues you describe.
I'll take
it up with the current code owner to find out the position on
allowing
the call vs throwing an exception.
If the above is the cause of your problem, the solution is to
either use
a different session for the MessageProducers or to ensure
that you only
use the MessageProducers from within onMessage, whichever best meets
your application requirements. In general, you should always
ensure that
a Session is never used concurrently, which includes calls across the
set of objects created from that Session such as MessageProducers and
MessageConsumers. The exception is for calls to Connection
and Session
close. You need to keep in mind that the async delivery
mechanism also
counts as a Thread and is considered to own the Session if
there is at
least one MessageListener registered on the MessageConsumers of that
Session and the Connection is started. Section 4.4.6 Conventions for
Using a Session of the JMS spec' covers this in more detail.
Regards,
James.

Maybe the MessageListener was blocking the mechanism by which

Anybody got any ideas that might shed some light on this behavior?

I'm tearing my hair out with this. Any help would be much

Whenever I invoke MessageProducer.send() where the
MessageProducer has been defined on a Cluster Queue, it takes
about 5 seconds for the send method to return. However,
producing message to a local queue is quick.
Below is script that sets up the cluster.

It is meant to be a reboot of the queue manager to empty everything out and start
again fresh. This is a queue manager that I use in a test/development environment.
