lxb0970 : a new client machine! access using dfrodrig user

killing everything on a pattern:

kill -9 `ps -ag | egrep "consumerAgent" | awk '{print $1}'`

Back on track:

activemq.prefetchSize = ....


When subscribing a topic, we should be setting as an header the prefetchSize (number of messages to be sent to a particular client without getting any receipt that we will allow).

this should be sent as an header when subscribing!

Useful things for continuing the report

todo:

finish document under:
/afs/cern.ch/user/d/dfrodrig/workspace/docs/reports

Add more results to *.sxc :
/afs/cern.ch/user/d/dfrodrig/workspace/docs/testResults
Go get them at:
/afs/cern.ch/user/d/dfrodrig/workspace/GMAN/tests/results

lxb6117, lxb6118 configurations also under ~/workspace/docs/reports/tmp!

Command for running consumer: tail -n 100 -f cons | nc lxb6118 6163 > /tmp/tmp

and not referring to the report:

Getting this:

From time to time... I'll have to carefully analyse.


right now, I am running the tests veryfing saturation and before saturation. Up to now:

Configuration at lxb6118

James installed Activemq 5.0 (latest release )

configuration files are under

/etc/activemq

activemq-wrapper.conf (for configuring the activemq wrapping)
activemq.xml (for configuring the activemq broker)
log4j.properties

logs/journal are under /var/lib/activemq

and stopping starting has a dedicated start script :

service activemq start|stop

lxb6117 will keep activemq4.1.1

Brief notes on remake of the tests

Additional variables to take into account:

Maybe it' snot the same in 5.0
