<h1 class="topictitle1">Copy files that contain DataLinks</h1>
|
||
|
|
<div><p>You can specify CRTFILE(*YES) on the CPYF and CPYFRMQRYF commands
|
||
|
|
when you copy files that contain DataLinks (DLs). If the from-file is an SQL
|
||
|
|
table, view, or index that contains a DL, these commands create an SQL table.</p>
|
||
|
|
<p>You cannot copy DDM files that contain DataLinks to <span class="keyword">iSeries™</span> servers running at Version 4
|
||
|
|
Release 3 or earlier.</p>
|
||
|
|
<p>DLs can be mapped only to other DLs. Therefore, if you specify *NONE, *MAP,
|
||
|
|
or *DROP on the FMTOPT parameter, the from-file and to-file must have corresponding
|
||
|
|
DLs. Truncation is not allowed. Shorter DLs, however, can be converted to
|
||
|
|
longer DLs.</p>
|
||
|
|
<p>A file can be linked only once on a server. Therefore, a copy that will
|
||
|
|
perform mapping or that requires the formats to be identical (that is, *NONE,
|
||
|
|
*MAP, or *DROP is specified on the FMTOPT parameter) will not be successful
|
||
|
|
if corresponding from-file and to-file fields are both FILE LINK CONTROL.
|
||
|
|
Copies that are performed using the *NOCHK parameter option are not restricted,
|
||
|
|
but errors will occur if a DL that references a linked file is copied to a
|
||
|
|
DL that is FILE LINK CONTROL.</p>
|
||
|
|
<div class="p">When you specify CRTFILE(*YES) on the CPYF or CPYFRMQRYF command, and the
|
||
|
|
from-file contains a FILE LINK CONTROL DL field, the following statements
|
||
|
|
are true, depending on how you specify the FMTOPT parameter: <ul><li>If you specify *NONE, *MAP, or *DROP on the FMTOPT parameter, the file
|
||
|
|
is created, but an error message is issued and no I/O is performed.</li>
|
||
|
|
<li>If you specify *NOCHK or *CVTSRC on the FMTOPT parameter, the file is
|
||
|
|
created and I/O is attempted. The I/O will be unsuccessful for any records
|
||
|
|
that contain a valid LINK.</li>

||
|
|
