Hi,
I have a JMS queueing application application where I create 10 senders in one machine and 100 receivers in another machine. when starting the application, i'd get the error MQJMS2005 after some of the 100 receivers have been created ...
Thu Apr 04 18:55:32 EST 2002: javax.jms.JMSException: MQJMS2005: failed to create MQQueueManager for 'lcpw2k10b:' at com.ibm.mq.jms.MQQueueConnection.createQM(MQQueueConnection.java:479)
at com.ibm.mq.jms.MQQueueConnection.<init>(MQQueueConnection.java:183)
at com.ibm.mq.jms.MQQueueConnectionFactory.createQueueConnection(MQQueueConnectionFactory.java:167)
at perfQueue.<init>(perfQueue.java:133)
at perfQueue.main(perfQueue.java:93)
at com.ibm.mq.jms.services.ConfigEnvironment.newException(ConfigEnvironment.java:434)
at com.ibm.mq.jms.MQQueueConnection.createQM(MQQueueConnection.java:479)
at com.ibm.mq.jms.MQQueueConnection.createQueueSession(MQQueueConnection.java:268)
at perfQueue$queueObj.clearQueues(perfQueue.java:651)
On the server side ... it gave me the following ...
04/04/2002 18:32:49 AMQ9513: Maximum number of channels reached.
04/04/2002 18:32:49 AMQ9209: Connection to host '192.168.10.26' closed.
I tried creating more channels on the server for client and server connections as stated in the documentation using ..
DEFINE CHANNEL(CHAN2) CHLTYPE(SVRCONN) TRPTYPE(TCP) +
DESCR('Server connection to Client_2')
DEFINE CHANNEL(CHAN2) CHLTYPE(CLNTCONN) TRPTYPE(TCP) +
CONNAME(9.20.4.26) QMNAME(QM2) DESCR('Client connection to Server_2')
I created 100 of these and specified the MQCHLLIB on the client side to locate the client channel definition table, again as stated in the docs - but I still couldnt connect all my 100 receivers.
Am I missing anything? How can make MQseries accept more simultaneous conenctions?
Thanks,
tyrone |

Tyrone,
check out Paul Clarke's (Hursley lab) answer on a similar question: http://www.messageq.com/forums/vienna/msg_body.php3?ID=27866
It describes the qm.ini entry you need to add for your maximum number of channel connections:
Channels:
MaxChannels=nnnnn
You do not need to define more channels, you just need to raise the above MaxChannels number (100 is the default).
The System Administration Guide for your platform contains the detailed info.
Hope that helps,
Stefan
