<h1 class="topictitle1">CCSID conversion considerations for DB2 Universal Database for z/OS and DB2
|
||
Universal Database server for VM database managers</h1>
|
||
<div><p>One of the differences between a <span class="keyword">DB2 Universal Database™ for iSeries™</span> and
|
||
other DB2<sup>®</sup> databases
|
||
is that the iSeries system
|
||
supports a larger set of CCSIDs. This can lead to errors when the other database
|
||
managers attempt to perform character conversion on the data (SQLCODE –332
|
||
and SQLSTATE 57017).</p>
|
||
<div class="section"><p>Certain fields in the <span class="keyword">DB2 UDB SQL</span> catalog
|
||
tables might be defined to have a DBCS-open data type. This is a data type
|
||
that allows both double-byte character set (DBCS) and single-byte character
|
||
set (SBCS) characters. The CCSID for these field types is based on the default
|
||
CCSID shipped with the server.</p>
|
||
</div>
|
||
<div class="section"><p>When these fields are selected from a DB2 Universal Database for z/OS<sup>®</sup> or DB2
|
||
Universal Database Server for VM application requester (AR), the SELECT
|
||
statement might fail because the DB2 Universal Database for z/OS and DB2
|
||
Universal Database Server for VM databases might not support the conversion
|
||
to this CCSID.</p>
|
||
</div>
|
||
<div class="section"><p>To avoid this error, you must change the DB2 Universal Database for z/OS database
|
||
or the DB2
|
||
Universal Database Server for VM AR to run with either one of the following
|
||
items: </p>
|
||
<ul><li>The same mixed-byte CCSID as the DBCS-OPEN fields in the <span class="keyword">iSeries</span> SQL
|
||
catalog tables.</li>
|
||
<li>A CCSID that the server allows conversion of data to when the data is
|
||
from the mixed-byte CCSID of the DBCS-OPEN fields in the <span class="keyword">iSeries</span> SQL
|
||
catalog tables. This CCSID might be a single-byte CCSID if the data in the <span class="keyword">iSeries</span> SQL catalog tables DBCS-OPEN
|
||
fields is all single-byte data.</li>
|
||
</ul>
|
||
<p>This requires some analysis of the CCSID conversions supported on
|
||
the DB2
|
||
Universal Database for z/OS or DB2 Universal Database Server
|
||
for VM so you can make the correct changes to your server. See the <cite>DB2 UDB
|
||
for z/OS Administration
|
||
Guide</cite> for specific information on how to handle this error.</p>
