<h1 class="topictitle1">Restrictions on the CPYFRMIMPF command</h1>
|
|
<div><p>There are certain restrictions that apply to the CPYFRMIMPF command.</p>
|
|
<ul><li>The data type of the from-file must be one of two types: <ul><li>A source physical file</li>
|
|
<li>A physical file with one field with a data type of CHARACTER, IGC OPEN,
|
|
IGC EITHER, IGC ONLY, GRAPHIC, fixed or variable length</li>
|
|
</ul>
|
|
</li>
|
|
<li>The copied records might have the same relative record numbers in the
|
|
to-file as in the from-file.</li>
|
|
<li>Create the to-file before copying.</li>
|
|
<li>RCDDEL *ALL finds the first occurrence of CRLF, LFCR, CR, or LF. This
|
|
value will be used as the RCDDEL throughout the rest of the program.</li>
|
|
<li>The to-file and from-file cannot be the same file. <ul><li>If a record from the from-file cannot be imported, the process continues
|
|
based on the Errors Allowed (ERRLVL) parameter. When ERRLVL(*NOMAX) is defaulted
|
|
or specified while the ERRRCDFILE parameter is being used, incorrect error
|
|
records might be written to the ERRRCDFILE. This occurs for two reasons: record
|
|
blocking is performed from ERRLVL(*NOMAX) or because the copy might be using
|
|
multiple tasks to perform the request. To avoid having the incorrect records
|
|
appearing in the error record file, follow either of the following two suggestions:
|
|
use the ERRLVL(*NOMAX) parameter only after knowing the data can be copied
|
|
correctly or specify a numeric value rather than *NOMAX. When specifying a
|
|
numeric value, all the error records will be written to the ERRRCDFILE until
|
|
the ERRLVL number is exceeded or the end of file is reached. <div class="note"><span class="notetitle">Note:</span> Note that
|
|
you will need to specify a high enough number in order for the CPYFRMIMPF
|
|
to make it through the entire file.</div>
|
|
</li>
|
|
<li>If the from-file is a source file, the server does not copy the first
|
|
12 bytes of the record (Sequence field and Date field). If the to-file is
|
|
a source file, the server sets the first 12 bytes of the to-file's data (Sequence
|
|
field and Date field) to zeros.</li>
|
|
</ul>
|
|
</li>
|
|
</ul>
|
|
<p>You can use this command on files that contain user-defined types (UDTs),
|
|
user-defined functions (UDFs), identity columns, ROWIDs, and large objects
|
|
(LOBs). You cannot use this command on files that contain DataLinks (DLs).</p>
|
|
<p>Using the CPYFRMIMPF command with a JOBCCSID of 65535 might produce inaccurate
|
|
or unpredictable results.</p>
