MQSeries.net :: View topic - Stress Test Issues; Establishing a TCP/IP Connection

objectthinker06 · Posted: Sun Mar 25, 2007 4:47 am Post subject:

I'm a Java Developer and not a MQ Admin so my admin knowledge is limited. And from the intercommunication manuals I see that there are two ways to establish a TCP/IP connection namely :

a) Using inetd or
b) Using runmqlsr

My MQAdmin has done both in the above for the Queue Managers that I'm using. From this board/other resources I learnt that using runmqlsr is recommended over inetd for MQ v 5.3 and up. So the question is: i) Is it correct to use both ways (inetd and runmqlsr) for running a queue manager ? ii) If its ok to use inetd and runmqlsr then which one overrides what at runtime ?

I'm stress testing a client using WMQ Client to connect to the WMQ Server via a Server Connection Channel over JMS. On the WMQ Server node after stress tests I observed that there are approx. 70 amqcrsta processes running and during stress tests under peak load the Queue Manager becomes unresponsive and the client throws a 2059 error code (the # of amqcrsta processes under peak load haven't been recorded as of the last test).

Any possible leads where to start troubleshooting such an issue ?

Thanks in advance,
