         This extension point allows tool-writers to extend the capability
of the Remote System Explorer,
by identifying a subsystem configuration that produces a subsystem
whenever a new connection is created.
This subsystem appears under the connection when it is expanded
in the Remote Systems view of
the Remote System Explorer perspective. The subsystem configuration
is called by the Remote System
framework when the user creates a new connection, when the connection&apos;s
system type is one of the
types identified as supported by this subsystem configuration extension.

&lt;p&gt;
There is one subsystem
object per connection, and the role of a subsystem is to allow
users to work with remote resources
for the remote system identified by the containing connection.
Defining a subsystem configuration involves more than the single subsystem
configuration class. There must
also be a subsystem class defined, and a system class defined.
There may also be other classes
defined, such as classes for the content area of wizards for
defining filters, user actions 
and compile commands, if the subsystem configuration wishes to support
these. See the developer documentation for the Remote System Explorer
for documentation details on defining
subsystems.

                  This optional attribute allows subsystem providers to classify
the type of remote resources
that are listed by this subsystem configuration. It is possible for
multiple subsystem factories to
support the same remote resource category. This category is used
in the popupMenus and
propertyPages extension points, to scope actions and property
pages to only remote resources
of a particular category, via their &lt;samp&gt;subsystemconfigurationCategory&lt;/samp&gt; attribute. 
For example, if listing database resources
you might specify a 
category of &quot;database&quot;.
IBM-supplied categories include &quot;files&quot;, &quot;cmds&quot; and &quot;jobs&quot;.

Only used when naming an IBM-supplied subsystem configuration in the &lt;samp&gt;class&lt;/samp&gt; attribute, when you want to subclass or replace the IBM-supplied ISystem object used to manage the live connection with the remote system.

         Example of using this extension point:

&lt;p&gt;
&lt;pre&gt;
   &lt;extension 
      point=&quot;org.eclipse.rse.ui.subsystemconfiguration&quot;&gt;
      &lt;configuration
         systemtypes=&quot;Unix;Linux;Local&quot; 
         name=&quot;Databases&quot;
         icon=&quot;icons/dbsubsys.gif&quot; 
         iconlive=&quot;icons/dbsubsyslive.gif&quot;
         id=&quot;com.acme.etools.mypkg.myconfiguration&quot;
         class=&quot;com.acme.etools.db.DBSubSystemFactory&quot;
         category=&quot;databases&quot;
         vendor=&quot;ACME&quot;
      &gt;
     &lt;/configuration&gt;
   &lt;/extension&gt;
&lt;/pre&gt;
&lt;/p&gt;

&lt;p&gt;Defining the xml for the extension point is easy. There is a fair amount to know about
creating the classes needed for a subsystem configuration, however. For this information, consult
the Remote System Explorer developer documention, including the JavaDoc for the supplied 
classes and interfaces for this task.
&lt;/p&gt;

         <meta.section type="apiInfo"/>
      </appInfo>
      <documentation>
         The provider of subsystem factories must implement the interface
&lt;samp&gt;com.ibm.etools.systems.subsystems.SubSystemFactory&lt;/samp&gt;,
although it is not recommended to create a new class from scratch.
Rather, it is highly recommended
to use the supplied base class &lt;samp&gt;org.eclipse.rse.core.subsystems.SubSystemConfiguration&lt;/samp&gt;.
This base class pre-supplies much functionality, including support for
persisting properties and metadata, and support for filters.

         All supplied subsystems are implemented via use of this extension point.
See the &lt;samp&gt;plugin.xml&lt;/samp&gt; files for plugins
&lt;samp&gt;org.eclipse.rse.subsystems.files.dstore&lt;/samp&gt; and
&lt;samp&gt;org.eclipse.rse.subsystems.processes.dstore&lt;/samp&gt;
for examples.
