<h2>Current Status</h2><a name="status">
<ol>
<li>The first cut of the new <a
href="http://www.omg.org/cgi-bin/doc?ptc/2003-07-02"> DnC </a>
specification implementation, which we call DAnCE is available in
this distribution. DAnCE is housed under <CODE> $CIAO_ROOT
</CODE>. We plan to enhance DAnCE in the next few months. We believe
DAnCE will replace existing tool sets in <CODE>
$CIAO_ROOT/tools</CODE>. There are a few features in
<CODE>$CIAO_ROOT/tools</CODE> that are missing in the DAnCE
implementation. Please see <a href="../TODO.html"> TODO </a> file
for more details. We plan to implement them soon and use DAnCE
continuously.
<li> The first cut of DAnCE includes two parts:
<ul>
<li>
A modeling tool chain , <a href="http://www.dre.vanderbilt.edu/CoSMIC/">
CoSMIC</a>, which is capable of describing the Assembly/Component
using <a
href="http://www.isis.vanderbilt.edu/Projects/gme/default.html">
GME</a> as the development bed. The artifacts generated from the
CoSMIC are a set of XML descriptors.
<!-- Tao, I realy don't understand what this means - Bala -->
<li>This run-time infrastructure that performs the actual deployment
and configuration, with a superset of the capabilities described in
OMG DnC specification with CIAO extension. </a>.<p><p>
</ul>
<!-- Tao, can you please see whether this is needed -->
In the new DnC run-time framework we have migrated all the
functionalities present in the old CIAO runtime except the
Real-Time configuration and Static Configuration, which are
developed by Washington University in St. Louis. Currently,
the two CIAO runtime co-exist in our source and the component
implementation could be used with both framework without much
change. (For the change that one has to go through please
read <a href="./switch.html">this</a>.)<p>
<li> Two operations <CODE> ciao_preactivate ()</CODE> and
<CODE>ciao_postactivate ()</CODE> have been added to the
<CODE>SessionComponent</CODE> interface. This implies that component
developers have to implement those operations within the
executor. We plan to get around this, i.e., users having to
implement these two operations, in the next month or so. <p>
<li> The CIDL Compiler has been eliminated, all CIAO code is now
generated by the IDL compiler.<p>
<li> CIAO doesn't yet support features that help integrating CORBA
components with Enterprise Java Beans (EJB).<p>
<li> Test to demonstrate composition of applications with real-time
behavior using CIAO's real-time extension was added. Please see
ACE_wrappers/TAO/CIAO/tests/RTCCM/Priority_Test.<p>
<li> The CIAO static configurator tool has been enhanced to support
processing of RTCORBA policy related information. Please see
ACE_wrappers/TAO/CIAO/docs/static_ciao_index.html.<p>
<li> To further interoperability with non-component-aware clients, there
are files in the $CIAO_ROOT/tools/IDL3_to_IDL2 directory that can be
compiled into an executable called tao_idl3_to_idl2. This executable
takes an IDL file (on the command line) containing IDL3 declarations
and outputs an IDL file with the IDL3 declarations converted to
equivalent IDL2. IDL2 declarations in the input file are unchanged.
See the README file in that directory for more information.<p>
