|

|
|
<div><p>The <span class="cmdname">Display Physical File Member (DSPPFM)</span> command
|
||
|
|
can be used to display a remote file on a target server.</p>
|
||
|
|
<div class="section"><p>For performance reasons, however, whenever possible, you should
|
||
|
|
use display station pass-through to sign on the remote server, and display
|
||
|
|
the file directly. When display station pass-through is used, only the display
|
||
|
|
images are transmitted over the communications line. When DDM is used to access
|
||
|
|
the remote file, each record is transmitted separately over the line, which
|
||
|
|
requires many more transmissions.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>If pass-through cannot be used (for example, if the remote file
|
||
|
|
is not on an <span class="keyword">iSeries™ server</span>, a <span class="keyword">System/38™</span>, or a <span class="keyword">System/36™</span>,
|
||
|
|
or if pass-through is not configured on your server), direct record positioning
|
||
|
|
rather than relative positioning should be used whenever possible. For example,
|
||
|
|
if record number 100 is being displayed and you want to see record number
|
||
|
|
200 next, that record is accessed faster if you enter 200 in the control field
|
||
|
|
instead of +100. The results are the same, unless the file contains deleted
|
||
|
|
records.</p>
