Using `telnet` to Verify That the Message Queue Broker is Running

Verify that the Message Queue broker is running. Using the telnet command to connect to the machine and port where the Message Queue broker is running returns a list of the active Message Queue services:

# telnet localhost 7676
Trying 127.0.0.1...
Connected to localhost.
Escape character is \q^]\q.
101 psw-broker 3.0.1
cluster tcp CLUSTER 32914
admin tcp ADMIN 32912
portmapper tcp PORTMAPPER 7676
ssljms tls NORMAL 32913
jms tcp NORMAL 32911
Connection closed by foreign host.

If the ssljms tcp NORMAL service is not listed in the output, then examine the Message Queue logs for potential problems. The location of the log depends on the platform you are using as follows:

On Solaris, the log is in the following location: /var/imq/instances/psw-broker/log/log.txt
On Linux, the log is in the following location: /var/opt/sun/mq/instances/isw-broker/log/log.txt
On Windows, the log is in the following location: installation_root\isw-machine_name\imq\var\instances\isw-broker\log\log.txt

If the telnet command fails, then either the broker is not running or the wrong port was specified. Check the port number in the broker’s log. For example, the log contains a line for the broker's port as follows:

[13/Mar/2003:18:17:09 CST] [B1004]:
'Starting the portmapper service using tcp
[ 7676, 50 ]
with min threads 1 and max threads of 1'

If the broker is not running, start it on Solaris and Linux by running the /etc/init.d/imq start command. On Windows, start the broker by starting the iMQ Broker Windows service.

If you install Message Queue on Solaris 8, and you run the mquinstall command to install all of the packages, be sure to set IMQ_JAVAHOME propertybefore running the mqinstall command. This ensures that the software picks the correct version of Java.

If you have not yet installed the core component, you do not have to set the IMQ_JAVAHOME property because the Identity Synchronization for Windows installation program tells the Message Queue broker which version of Java to use.
