<div><p><span>You can specify whether object names in
|
||
|

the user-defined file system (UDFS) will be case-sensitive or case-insensitive

when you create it.</span></p>
|
||
|
|
<div class="section"><p>When you select case-sensitivity, uppercase and lowercase characters
|
||
|
|
are distinguished when searching for object names. For example, a name that
|
||
|
|
is supplied in all uppercase characters will not match the same name in which
|
||
|
|
any of the characters are lowercase. Therefore, <samp class="codeph">/home/MURPH/</samp> and <samp class="codeph">/home/murph/</samp> are
|
||
|
|
recognized as different directories. To create a case-sensitive UDFS, you
|
||
|
|
can specify *MIXED for the CASE parameter when using the <span class="cmdname">Create User-Defined
|
||
|
|
File System (CRTUDFS)</span> command.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>When you select case-insensitivity, the server does not distinguish
|
||
|
|
between uppercase and lowercase characters during searches for names. Therefore,
|
||
|
|
the server would recognize <samp class="codeph">/home/CAYCE</samp> and <samp class="codeph">/HOME/cayce</samp> as
|
||
|
|
the same directory, not as two separate directories. To create a case-insensitive
|
||
|
|
UDFS, you can specify *MONO for the CASE parameter when using the <span class="cmdname">CRTUDFS</span> command.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>In either case, the file system saves the same uppercase and lowercase
|
||
|
|
forms in which the user enters object names. The case-sensitivity option
|
||
|
|
only applies to how the user searches for names through the server.</p>
