I really need your help.
Our MQ Team told us they observed that our JBoss connection to MQRA . MQ Channel Restart Frequents.
Every 1-2 mins in average.
We are also getting following error when we enabled JBoss MQ Trace logs
"11:21:59.475.00 1128 CC=2;RC=2009;AMQ9213: A communications error for 'TCP' occurred."
This error appears very often And somehow match 1-2 mins in average.
Could you please shed more light on this error, would this be an error caused by Client or Server?
Error: IBM MQ AMQ9213: A communications error for TCP/IP occurred
Running EAP 6.3.3 and MQRA 18.104.22.168. Redhat 6
Our MQ Team raised RED-FLAG that the connections from JBoss MDB MqRA Channel connection keep restarting every 1-2 mins.
However, Yes Our JBOSS MQ MDB is able to connect/communicate with MQRA and have no problem connecting to it or pass messages.
(From application point of view)
When we turn on JBoss mq Trace log. We notice "11:21:59.475.00 1128 CC=2;RC=2009;AMQ9213: A communications error for 'TCP' occurred."
error from Jboss MQ Trace (every 1-2 mins I see this error as well)
What we have done SO far
Made changes to Standalone-ha.xml including :
- .Change heart beat
- .Change connection pools
#2)Made changes to ra.xml (wmq.jmsra.rar)
- "reconnectionRetryCount" and "reconnectionRetryInterval" to higher value.
However, we don't use wmq.jmsra.rar BUT we used extract version of wmq.jmsra.rar example : /opt/jboss/modules/com/ibm/mq/main/
(so there is no wmq.jmra.rar in the folder)
#3) Add system enviornment
%export MQNOREMPOOL to 1
(inside the Jboss startup shell script)
Restart Jboss same problem.
#4) I found this FixPack at IBM Websphere MQ - for error AMQ9213
What does this mean or relate my problem?
PS: Justin Bertram said "errors you receive from the IBM WebSphereMQ JCA RA are really a matter for IBM support" in the following Thread
BUT I need to be able to prove this.. We have IBM Websphere MQ PMR opened but how do I troubleshoot ..how do I proof this.. help..!!
How do I start? Any steps and procedures are appreciated of working with IBM MQ Rep
