<h1 class="topictitle1">Support for save files in the QSYS.LIB file system</h1>
|
|
<div><p>The QSYS.LIB file system supports stream I/O operations to save
|
|
file objects.</p>
|
|
<div class="section"><p>For example, an existing save file has data that
|
|
may be read out or copied to another file until it is necessary to place the
|
|
data into a different, existing, and empty save file object. When a save file
|
|
is open for writing, no other open instances of the file are allowed. A save
|
|
file <strong>does</strong> allow multiple open instances for reading, provided no job
|
|
has more than one open instance of the file for reading. A save file may not
|
|
be opened for read/write access. Stream I/O operations to save file data are
|
|
not allowed when multiple threads are running in a job.</p>
|
|
</div>
|
|
<div class="section"><p>Stream I/O operations on a save file are not supported when the
|
|
save file or its directory are being exported through the Network File System
|
|
server. They may, however, be accessed from PC clients and through the QFileSvr.400
|
|
file system.</p>
