SCF and the QIO Subsystem
Each QUEUE object is associated with an APPL object. The QUEUE name is defined
by the client process and must be unique within the segment. It is recommended that
the name of the APPL that is creating the queue be used as the prefix for the QUEUE
name. For example, $ZM02.#ZTC2.IN is the queue that belongs to the $ZTC2 client
process under the $ZM02 QIOMON process.
The QUEUE object represents the queues created by an APPL object and are thus
subordinate to the APPL object.
SCF and the QIO Subsystem
This section describes QIO management interfaces and shows how they fit into the
architecture of the QIO subsystem. Descriptions of QIO subsystem objects and
commands are presented.
The QIO subsystem is managed by entering interactive (SCF) commands for
subsystem objects.
The response to a command indicates whether or not the specified action was
successfully completed. If the command requires the subsystem to furnish information,
then the information is included in the response.
Figure 1-2 illustrates the relationship between SCF and the QIO subsystem.
Note. SCF provides an operator interface to an intermediate process, the Subsystem Control
Point (SCP), which in turn provides the interface to the QIOMON process.
