Managing Connections

The Command utility’s list cxn and query cxn subcommands display information about individual connections. The subcommand imqcmd list cxn lists all connections for a specified connection service:

   imqcmd list cxn  [-svn serviceName]
                    [-b hostName:portNumber]

If no service name is specified, all connections are listed. For example, the following command lists all connections on the default broker (host localhost at port 7676):

   imqcmd list cxn  -u admin

Example 6–4 shows an example of the resulting output.


Example 6–4 Broker Connections Listing


Listing all the connections on the broker specified by:
-----------------------------------
Host                   Primary Port
------------------------------------
localhost              7676

---------------------------------------------------------------------------
Connection ID         User    Service   Producers  Consumers    Host
---------------------------------------------------------------------------
1964412264455443200   guest   jms       0          1            127.0.0.1
1964412264493829311   admin   admin     1          1            127.0.0.1

Successfully listed connections.


To display detailed information about a single connection, obtain the connection identifier from imqcmd list cxn and pass it to the imqcmd query cxn subcommand:

   imqcmd query cxn   -n connectionID
                     [-b hostName:portNumber]

For example, the command

   imqcmd query cxn  -n 421085509902214374  -u admin

produces output like that shown in Example 6–5.

Connection ID      421085509902214374
User               guest
Service            jms
Producers          0
Consumers          1
Host               111.22.333.444
Port               60953
Client ID          
Client Platform    


The imqcmd destroy cxn subcommand destroys a connection:

   imqcmd destroy cxn   -n connectionID
                     [-b hostName:portNumber]

For example, the command

   imqcmd destroy cxn  -n 421085509902214374  -u admin

destroys the connection shown in Example 6–5.
