|
|
<div><p>You can use the Change Physical File (CHGPF) command to change
|
|
the coded character set identifier (CCSID) of a physical file. However, the
|
|
physical file cannot be changed under certain conditions.</p>
|
|
<p>A physical file cannot be changed if one or more of the following
|
|
conditions exist when working with a logical file defined over a physical
|
|
file:</p>
|
|
<ul><li>The logical file has a sort sequence table associated with the CCSID of
|
|
the physical file and the CCSID you want to change to is incompatible. That
|
|
is, conversion between the original CCSID and the CCSID you want to change
|
|
to is not allowed because all the characters of the original CCSID are not
|
|
in the new CCSID.</li>
|
|
<li>The logical file has a sort sequence table associated with the CCSID of
|
|
the physical file and the CCSID you want to change to is incompatible. Additionally,
|
|
the logical file has fields defined with CCSIDs that are not compatible to
|
|
the new CCSID you want to change the physical file to. Again, conversion between
|
|
the original CCSID and the CCSID you want to change to is not allowed because
|
|
all the characters of the original CCSID of the logical file or the fields
|
|
with specific CCSIDs are not in the new CCSID.</li>
|
|
<li>A select/omit or join logical file, or both that performs select/omits
|
|
or joins between physical file fields that have different CCSIDs.</li>
|
|
<li>A join logical file with a sort sequence table such that the CCSID of
|
|
the logical file's secondary access path is different than the CCSID to which
|
|
the physical file is being changed.</li>
|
|
</ul>
