|
||
|
|
<ul><li>Delete Capabilities: An <span class="keyword">iSeries™</span> direct
|
||
|
|
file is delete capable or nondelete capable. A nondelete capable file must

|
|
have an active default record.</li>
|
||
|
|
<li>Supported Record Classes: An <span class="keyword">iSeries</span> direct
|
||
|
|
file can have a fixed-length record (RECFIX) or variable-length record (RECVAR)
|
||
|
|
for storage. Once a non-<span class="keyword">iSeries</span> source
|
||
|
|
server opens a file on the <span class="keyword">iSeries</span> target
|
||
|
|
using variable-length record access, the <span class="keyword">iSeries</span> target
|
||
|
|
continues to send and receive variable-length records on all subsequent I/O
|
||
|
|
operations. <div class="note"><span class="notetitle">Note:</span> The <span class="keyword">iSeries server</span> does
|

|
|
not support the concept of a direct file. <span class="keyword">i5/OS</span> DDM
|

|
|
creates a direct file by creating a nonkeyed physical file and initializing
|
||
|
|
it, with deleted or active default records, to the maximum size requested.
|
||
|
|
No extensions to the file are allowed.</div>
