<h1 class="topictitle1">Example: Using the user-defined communications programs for file transfer</h1>
|
||
|
|
<div><p>This example shows how X.25-oriented applications use the user-defined
|
||
|
|
communications support to connect to remote systems.</p>
|
||
|
|
<div class="section"><p>Two user-defined application programs written in the ILE C programming
|
||
|
|
language are used to illustrate a simple file transfer between two systems
|
||
|
|
over an X.25 packet-switching data network (PSDN). Although an X.25 example
|
||
|
|
is shown, many of the same concepts can be applied to applications running
|
||
|
|
over token-ring and Ethernet local area networks (LANs). For the purposes
|
||
|
|
of the examples, the APIs are referred to by their call names. The includes <em>header</em>, <em>hexconv</em>,
|
||
|
|
and <em>typedefs</em> are not in QSYSINC. These includes are only documented
|
||
|
|
in the examples.</p>
|
||
|
|
<p>For this example, the following network configuration
|
||
|
|
will be used.</p>
|
||
|
|

</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">X.25 overview</h4><p>In this example X.25 network, the
|
||
|
|
source application on System A is responsible for establishing a switched
|
||
|
|
virtual circuit, or connection to the target application running on System
|
||
|
|
B. This is done by using the remote network address (System B's address) of
|
||
|
|
X'0000652'. When the target application on System B is initialized, it waits
|
||
|
|
for notification of an incoming call packet before proceeding. Once the virtual
|
||
|
|
circuit is established, the source application reads records from a file into
|
||
|
|
its output buffer and sends them to the target application using normal X.25
|
||
|
|
data transfer procedures. While receiving the file data, the target application
|
||
|
|
writes the data to a local file on System B. When the file transfer completes,
|
||
|
|
the source application closes the connection by issuing an X.25 clear request
|
||
|
|
packet and ends. When receiving the clear indication packet, the target application
|
||
|
|
also ends.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">User-defined communications support overview</h4><p>Both
|
||
|
|
the source and target applications call the Query Line Description (QOLQLIND)
|
||
|
|
API to obtain information about the local X.25 line being used. This information
|
||
|
|
is stored in a local control block for use in establishing the peer connection
|
||
|
|
during X.25 connection processing. Both applications also call the Enable
|
||
|
|
Link (QOLELINK) API to enable the link for future communications. The iSeries™ server
|
||
|
|
line name, communications handle, and remote DTE address are passed to both
|
||
|
|
programs as arguments to the C function main(). For simplicity, the user space
|
||
|
|
names and data queue name on the call to the QOLELINK API are coded directly
|
||
|
|
in the applications.</p>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> Keyed data queue support is used by both applications.
|
||
|
|
The key length is 3 and the keys used are source (SRC) and target (TGT) for
|
||
|
|
the source and target applications, respectively.</div>

<p id="apiexustran__Header_38"><a name="apiexustran__Header_38"><!-- --></a><strong>Activating
|
||
|
|
filters</strong></p>
|
||
|
|
<p>Once the links have been enabled and both applications have
|
||
|
|
read their respective enable-complete entries from their data queues, the
|
||
|
|
target application program calls the Set Filter (QOLSETF) API to activate
|
||
|
|
a filter. The filter activated then identifies the protocol of the local X.25
|
||
|
|
service user. This filter is used by the user-defined communications support
|
||
|
|
on System B to route incoming calls. The actual filter type activated is X'00'
|
||
|
|
(for X.25 PID) and its associated value is X'21'. For more information concerning
|
||
|
|
filters, see Set Filter (QOLSETF) API. After activating the X'21' filter,
|
||
|
|
the target application waits for the source application to request a connection.</p>
|
||
|
|
<p id="apiexustran__Header_39"><a name="apiexustran__Header_39"><!-- --></a><strong>Establishing a connection</strong></p>
|
||
|
|
<p>The source application
|
||
|
|
calls the Send Data (QOLSEND) API with a X'B000' operation in its output data
|
||
|
|
buffer to establish a switched virtual circuit (SVC) to the target application.
|
||
|
|
Included in the first byte of the call user data is the protocol ID of the
|
||
|
|
target application, or X'21'. When the user-defined communications support
|
||
|
|
on System B sees the incoming call packet with the first byte of user data
|
||
|
|
equal to a previously activated filter, the call is routed to the process
|
||
|
|
responsible for activating that filter. In this case, the target application
|
||
|
|
will receive notification of an incoming call since it previously activated
|
||
|
|
filter X'21'.</p>
|
||
|
|
<p>While waiting for the incoming call, the target application
|
||
|
|
calls the Receive Data (QOLRECV) API to receive a X'B201' operation with incoming
|
||
|
|
call data. After doing so, the target application accepts the X.25 connection
|
||
|
|
by calling the QOLSEND API with a X'B400' operation in its output data buffer.
|
||
|
|
See for more information.</p>

<p id="apiexustran__Header_40"><a name="apiexustran__Header_40"><!-- --></a><strong>Sending data</strong></p>
|
||
|
|
<p>Once
|
||
|
|
the peer connection is established between the source and target applications
|
||
|
|
running on System A and System B respectively, the file transfer takes place.
|
||
|
|
The source application reads records from a local file and calls the QOLSEND
|
||
|
|
API with X'0000' operations in its output data buffer to transfer the file
|
||
|
|
data to System B. This process continues until the entire contents of the
|
||
|
|
source file has been sent to System B.</p>
|
||
|
|
<p id="apiexustran__Header_41"><a name="apiexustran__Header_41"><!-- --></a><strong>Receiving data</strong></p>
|
||
|
|
<p>After
|
||
|
|
accepting the X.25 connection, the target application waits until its data
|
||
|
|
queue receives incoming-data entries. When the first entry is read from the
|
||
|
|
queue, the QOLRECV API is called to determine which operation was received.
|
||
|
|
Barring failure, the target application should receive a X'0001' operation
|
||
|
|
as a result of the QOLRECV API call. The data contained in the input data
|
||
|
|
buffer is the file data received from System A. While receiving the file data,
|
||
|
|
the target application writes the data to a local file. This process continues
|
||
|
|
until the entire contents of the file is received from System A. The target
|
||
|
|
application then assumes the file transfer is complete when an operation other
|
||
|
|
than a X'0001' operation is received after a successful call to the QOLRECV
|
||
|
|
API. Most likely, the first non-X'0001' operation received will be X'B301'
|
||
|
|
operation, signalling that the user-defined communications support running
|
||
|
|
on System B received an SVC clear indication.</p>

|
<p id="apiexustran__Header_42"><a name="apiexustran__Header_42"><!-- --></a><strong>Clearing
|
||
|
|
the connection and disabling links</strong></p>
|
||
|
|
<p>Once the entire contents of the
|
||
|
|
file has been read and sent to System B, the source application calls the
|
||
|
|
QOLSEND API with a X'B100' operation in its output data buffer to clear the
|
||
|
|
X.25 connection. Afterwards, the source application closes its local file,
|
||
|
|
disables its local link by calling the QOLDLINK API, and ends.</p>
|
||
|
|
<p>When
|
||
|
|
the source application program sends a X'B100' operation, it causes the target
|
||
|
|
application to receive a X'B301' operation. After receiving this operation,
|
||
|
|
the target application program calls the QOLSEND API with a X'B100' operation
|
||
|
|
to locally close the connection between itself and the user-defined communications
|
||
|
|
support. Afterwards, the target application closes its local file, disables
|
||
|
|
its local link by calling the QOLDLINK API, and ends.</p>

<p id="apiexustran__Header_43"><a name="apiexustran__Header_43"><!-- --></a><strong>Using
|
||
|
|
timers and the data queue support</strong></p>
|
||
|
|
<p>Both the source and target application
|
||
|
|
programs use the user-defined communications support timer service to manage
|
||
|
|
the reception of certain operations. This is done by setting a timer before
|
||
|
|
checking the data queue for an entry. For example, the target application
|
||
|
|
sets a timer to manage the reception of file data from the source application.
|
||
|
|
If the timer expires, the user-defined communications support places a timer-expired
|
||
|
|
entry on the application's data queue. The target application then assumes
|
||
|
|
when receiving this entry that the source application ended abnormally. The
|
||
|
|
target application can then take the appropriate action to end itself.</p>
