Windows default configuration objects

On Windows systems, you set up a default configuration using either the WebSphere MQ First Steps application or the WebSphere MQ Postcard application.

We cannot set up a default configuration if other queue managers exist on your computer.

Many of the names used for the Windows default configuration objects involve the use of a short TCP/IP name. This is the TCP/IP name of the computer, without the domain part; for example the short TCP/IP name for the computer mycomputer.hursley.ibm.com is mycomputer. In all cases, where this name has to be truncated, if the last character is a period (.), it is removed.

Any characters within the short TCP/IP name that are not valid for WebSphere MQ object names (for example, hyphens) are replaced by an underscore character.

Valid characters for WebSphere MQ object names are: a to z, A to Z, 0 to 9, and the four special characters / % . and _.

The cluster name for the Windows default configuration is DEFAULT_CLUSTER.

If the queue manager is not a repository queue manager, the objects listed in Table 1 are created.

Objects created by the Windows default configuration application
Object Name
Queue manager The short TCP/IP name prefixed with the characters QM_. The maximum length of the queue manager name is 48 characters. Names exceeding this limit are truncated at 48 characters. If the last character of the name is a period (.), this is replaced by a space ( ).
The queue manager has a command server, a channel listener, and channel initiator associated with it. The channel listener listens on the standard WebSphere MQ port, port number 1414. Any other queue managers created on this machine must not use port 1414 while the default configuration queue manager still exists.
Generic cluster receiver channel The short TCP/IP name prefixed with the characters TO_QM_. The maximum length of the generic cluster receiver name is 20 characters. Names exceeding this limit are truncated at 20 characters. If the last character of the name is a period (.), this is replaced by a space ( ).
Cluster sender channel The cluster sender channel is initially created with the name TO_+QMNAME+. Once WebSphere MQ has established a connection to the repository queue manger for the default configuration cluster, this name is replaced with the name of the repository queue manager for the default configuration cluster, prefixed with the characters TO_. The maximum length of the cluster sender channel name is 20 characters. Names exceeding this limit are truncated at 20 characters. If the last character of the name is a period (.), this is replaced by a space ( ).
Local message queue The local message queue is called default.
Local message queue for use by the WebSphere MQ Postcard application The local message queue for use by the WebSphere MQ Postcard application is called postcard.
Server connection channel The server connection channel allows clients to connect to the queue manager. Its name is the short TCP/IP name, prefixed with the characters S_. The maximum length of the server connection channel name is 20 characters. Names exceeding this limit are truncated at 20 characters. If the last character of the name is a period (.), this is replaced by a space ( ).

If the queue manager is a repository queue manager, the default configuration is similar to that described in Table 1, but with the following differences:

The queue manager is defined as a repository queue manager for the default configuration cluster.
There is no cluster-sender channel defined.
A local cluster queue that is the short TCP/IP name prefixed with the characters clq_default_ is created. The maximum length of this name is 48 characters. Names exceeding this length are truncated at 48 characters.

If you request remote administration facilities, the server connection channel, SYSTEM.ADMIN.SVRCONN is also created.
