Re: Confusion: why MQJMS objects need a port? - thanks for all the helps.
Hi Roger, thanks a lot for pointing out this. Our web developers are using Websphere, it looks like WAS uses its own JNDI repository. I checked with JMSAdmin, there is not even such queues defined for the application. In between, I wrote a few MQJMS test programs and setup Q, and QCF in the jndi name space. they all work fine without any channel and port involved. many thanks for all the helping tips from everyone. -Paul From: Roger Lacroix [EMAIL PROTECTED] To: MQSeries List [EMAIL PROTECTED] CC: [EMAIL PROTECTED] Subject: Re: Confusion: why MQJMS objects need a port? Date: Thu, 18 Sep 2003 13:49:48 -0400 Hi Paul, Check your JNDI values with the JSMAdmin tool. You probably set your QCF with the following command: define qcf(qcfClient) qmgr(MY.QMGR) channel(SYSTEM.DEF.SVRCONN) hostname (MYHOSTNAME) port(1414) transport(CLIENT) Hence, you needing to increase the max channel attribute even though it is local. Try the following: define qcf(qcfClient) qmgr(MY.QMGR) transport(BIND) This will not use any channels and should be faster. Hope that helps.

Quoting Paul Celari [EMAIL PROTECTED]: Hi, I just started with MQ-JMS, am trying to create administered objects, a Q and a QCF using the JMSadmin tool. But I don't understand why a port property is needed in these definitions. Actually, our web developers wrote a few message-driven beans to test, when the volumn get high, msg get stuck in queues, and from the qmgr error log, I can see MQ complained about maxchannel reached. I added a stanza Channels: in the mq.ini file and set MaxChannels=500, seem to solve the problem temporily. But I wonder why a MQ application will need to access a channel. Our applications and qmgr are all on the same box. We're not using client connection either. So I'm truely confused. The manual seem unable to clarify these. I may need a new mind set for JMS. I've only wrote C and MQJava-base programs before.

Re: Confusion: why MQJMS objects need a port?
Paul, I just started with MQ-JMS, am trying to create administered objects, a Q and a QCF using the JMSadmin tool. But I don't understand why a port property is needed in these definitions. You shouldn't need a PORT property defined. According to the Using Java manual, you only need to specify the PORT property when the TRANSPORT property is CLIENT or DIRECT. In fact, if I am reading the manual correctly (page 53/54) it is an error to set the PORT property without setting the TRANSPORT property to CLIENT or DIRECT. You might want to run a JMS trace and see what's really happening.

Re: Confusion: why MQJMS objects need a port?
Paul, the PORT attribute is not used for the MQSeries JMS transport. IBM introduced JMS over IP for publish/subscribe applications (supported with WBIMB V5) and that's where the port comes into play. If you have a local Java application and see the queue manager complain about channel limits, you might have configured your JNDI objects incorrectly. Make sure that the TRANSPORT property is set to the correct value for server bindings (can't remember the exact value, but it shouldn't contain CLIENT).
