<h1 class="topictitle1">ODBC policy: Prevent use of named data sources</h1>
|
||
|
|
<div><p>Use this policy to restrict the use of named data sources when
|
||
|
|
using iSeries™ Access
|
||
|
|
for Windows<sup>®</sup> ODBC
|
||
|
|
support.</p>
|
||
|
|
<p>A "named data source" is one that:</p>
|
||
|
|
<ul><li>has been created by the user or a program and given a specific name, and</li>
|
||
|
|
<li>is specified using the <span class="uicontrol">DSN</span> option when connecting.</li>
|
||
|
|
</ul>
|
||
|
|
<p>A user may create a named data source using the iSeries Access for Windows ODBC
|
||
|
|
Administration program. A program may create a named data source too -- by
|
||
|
|
calling, for example, SQLCreateDataSource.</p>
|
||
|
|
<p>A program may create an ODBC connection by calling SQLDriverConnect. If
|
||
|
|
the DSN option is used, it specifies a named data source to use. If the FILEDSN
|
||
|
|
option is used, it specifies the name of a file that contains connection options.
|
||
|
|
The file name is not a data source name, hence use of FILEDSN is not use of
|
||
|
|
a named data source.</p>
|
||
|
|
<p>The restriction options for this policy are the following:</p>
|
||
|
|
<ul><li><span class="uicontrol">Allow all:</span> All named data sources may be used.</li>
|
||
|
|
<li><span class="uicontrol">Allow listed sources:</span> Only those sources specifically
|
||
|
|
listed in this policy may be used. To view or change the list, click the Show
|
||
|
|
button.</li>
|
||
|
|
<li><span class="uicontrol">Prevent using named data sources:</span> No named data
|
||
|
|
sources may be used.</li>
|
||
|
|
</ul>
|
||
|
|
<p>If when connecting no named data source is specified, the data source used
|
||
|
|
will be a temporary one, called a "program generated data source." The use
|
||
|
|
of program generated data sources can be restricted using the Prevent use
|
||
|
|
of program generated data sources policy.</p>
|
||
|
|
<p>This policy is an override of <span class="uicontrol">machine setting enabled</span>.</p>
