|
<div><p>If you are running a distributed application and one of your systems
|
|
is not an <span class="keyword">iSeries™</span> system, the
|
|
job CCSID value on the <span class="keyword">iSeries</span> server
|
|
cannot be set to 65535.</p>
|
|
<div class="section"><p>Before requesting that the remote system create an SQL package,
|
|
the application requester always converts the name specified on the RDB parameter,
|
|
SQL package name, library name, and the text of the SQL package from the CCSID
|
|
of the job to CCSID 500. This is required by DRDA<sup>®</sup>. When the remote relational database
|
|
is an <span class="keyword">iSeries</span> system, the names
|
|
are not converted from CCSID 500 to the job CCSID.</p>
|
|
</div>
|
|
<div class="section"><p>It is recommended that delimited identifiers not be used for table,
|
|
view, index, schema, library, or SQL package names. Conversion of names does
|
|
not occur between systems with different CCSIDs. Consider the following example
|
|
with system A running with a CCSID of 37 and system B running with a CCSID
|
|
of 500. </p>
|
|
</div>
|
|
<div class="section"> <ul><li>Create a program that creates a table with the name "a¬b|c" on system
|
|
A.</li>
|
|
<li>Save program "a¬b|c" on system A, then restore it to system B.</li>
|
|
<li>The code point for ¬ in CCSID 37 is x'5F' while in CCSID 500 it is x'BA'. </li>
|
|
<li>On system B the name displays "a[b]c". If you created a program that referenced
|
|
the table whose name was "a¬b|c.", the program will not find the table.</li>
|
|
</ul>
|
|
</div>
|
|
<div class="section"><p>The at sign (@), pound sign (#), and dollar sign ($) characters
|
|
should not be used in SQL object names. Their code points depend on the CCSID
|
|
used. If you use delimited names or the three national extenders, the name
|
|
resolution functions may possibly fail in a future release.</p>
