<div><p><span>The addition of the integrated file
|
|
system to the <span class="keyword">iSeries™ server</span> server
|
|
in V3R1M0 did not affect existing <span class="keyword">iSeries</span> server
|
|
applications. The programming languages, utilities, and system support (such
|
|
as data description specifications) operate in the same way as
|
|
they did before the addition of the integrated file system.</span></p>
|
|
<p>To take advantage of the stream files, directories, and other support of
|
|
the integrated file system, however, you must use a set of application program
|
|
interfaces (APIs) provided for accessing integrated file system functions.</p>
|
|
<p>Additionally, the addition of the integrated file system allows you to
|
|
copy data between physical database files and stream files. You can perform
|
|
this copy using CL commands, the data transfer function of <span class="keyword">iSeries Access Family</span>,
|
|
or APIs.</p>

<li class="ulchildlink"><strong><a href="rzaaxstmpgm.htm">Copy data between stream files and database files</a></strong><br />
|
|
If you are familiar with operating on database files using record-oriented facilities such as data description specifications (DDS), you may find some fundamental differences in the way you operate on stream files.</li>
|
|
<li class="ulchildlink"><strong><a href="rzaaxcopydatastreamsave.htm">Copy data between stream files and save files</a></strong><br />
|
|
<span>A save file is used with save and
|
|
restore commands to retain data that would otherwise be written on tape or
|
|
diskette.</span></li>
|
|
<li class="ulchildlink"><strong><a href="rzaaxprogapi.htm">Perform operations using APIs</a></strong><br />
|
|
Many of the application program interfaces (APIs) that perform operations on integrated file system objects are in the form of C language functions.</li>
|
|
<li class="ulchildlink"><strong><a href="rzaaxsock.htm">Socket support</a></strong><br />
|
|
If your application is using the <span class="q">"root"</span> (/), QOpenSys, or
|
|
user-defined file systems, you can take advantage of the integrated file system <dfn class="term">local socket</dfn> support. A local socket object
|
|
(object type *SOCKET) allows two jobs running on the same system to establish
|
|
a communications connection with each other.</li>
|
|
<li class="ulchildlink"><strong><a href="rzaaxnlsname.htm">Naming and international support</a></strong><br />
|
|
The support for the <span class="q">"root"</span> (/) and QOpenSys file systems ensures
|
|
that the characters in object names remain constant across encoding schemes
|
|
used for different national languages and devices.</li>
|
|
<li class="ulchildlink"><strong><a href="rzaaxdtacvn.htm">Data conversion</a></strong><br />
|
|
When you access files through the integrated file system, data in the files may or may not be converted, depending on the open mode requested when the file is opened.</li>
|
|
<li class="ulchildlink"><strong><a href="rzaaxcfunctionexample.htm">Example: Integrated file system C functions</a></strong><br />
|
|
This simple C language program illustrates the use of several integrated file system functions.</li>
