Hi All,
I am using Jboss application server for my application and placing XML messages on MQ queue.It is working fine ,But If I keep the application idle for more than 2:30 hours ,channel is getting closed .(MQ queue and MQ manager are not null)and it is throwing
com.ibm.mq.MQException: MQJE001: Completion Code 2,Reason 2195,followed by Completion Code 2,Reason 2009 errors for each message.If I restart the application it is working fine.I have observed the exception every time when i kept the app idle for more time.
I tried to check any setting in jboss causing this time out.But not able to trace it out. Here is the exception stack trace..
INFO <STDOUT> MQJE001: An MQException occurred: Completion Code 2, Reason 2195

Check out the ProbeId in the FDC file associated with the 2195. The 2009 errors are probably side effects of the original 2195.
Also post what level of software you're using on what platform, if the FDC doesn't reveal an obvious cause.

Hi
2009 0x000007d9 MQRC_CONNECTION_BROKEN
means your client to server channels are broken or down.
This could be due to server qmgr not available or populated with lot of client/server channels.

I think that's already been determined. The question is why are they down, which I suspect is associated with the queue manager throwing a 2195.

Yes Vitor...
some un-expected behaviour happened on the queue manager side.
as you said is correct.
I think he has to check if any orphan processes are there in the system which crossed the user limit too. as he is using client / server

Hi all,
Thanks for your replies.
I am using 6.0.2.1 com.ibm.mq.jar ,on linux box.I could see Qmanager,queue values.As you said channel could be broken.
I am wondering ..If it is because lots of connectons why it is not coming at the begining and once after I restart..
Can I have any settings that can keep channel alive ,till I explicitly close it..
Thanks

If you'd looked in the FDC file as I suggested you wouldn't have to wonder.
And if the channel had decided to close because a timeout value had expired, I wouldn't expect a 2195!

Sorry to say that at the moment I do not have access to FDC files. I am trying to get the file.
In case If lots of connections opened ,is this exception expected..?
Thanks,

As I'm sure you've discovered from your research:
| Code: |
| 2195 0x00000893 MQRC_UNEXPECTED_ERROR |
So by definition it's unexpected.
It's possible a 2009 could result if the server was loaded, and short of resource for new connections. My reasoning here is that a queue manager error has occured and as a result the connections have broken.

Could someone can explain more on this please.

Each 2195 code is supposed to be accompanied with an FDC file; that's sort of the point. Sounds like you need to raise a PMR with IBM.

Hi,
I was able to get the java mq trace for this exception.If I keep the application idle for than 2 hours , connection is getting rest and channel is getting closed.
Could you look into this and suggest me on this please.

Hmmm. The first thing I though of when I read that is that the defaut TCP KeepAlive value on a server is usually 2 hours. If your are connecting to the QM as an MQ Client over a SVRCONN channel, and the server's KeepAlive is 2 hours, and the QM has been told to use KeepAlive (set by the MQ Admin in the qm.ini file) I can see how the QM would terminate your channel after 2 hours of no activity.
Why does your app stay connected for over 2 hours doing nothing? Wouldn't it make more sense to disconnect from MQ and reconnect when you have something to do?

This app has to run continuosly through out the day.it could be idle for couple of hours at times ,because of no users or for some other reasons.
so every time it has to be manually restarted to get the connection back.
Are we having any settings that keep the connection or channel alive for ever ,until and unless if there are any issues from qmanager..? |
