Release Information for the Deployment And Configuration Engine (DAnCE)
This document contains information on the following topics related to the
current
release of CIAO:
Current Status
- The first cut of the new DnC
specification implementation, which we call DAnCE is available in
this distribution. DAnCE is housed under
$DANCE_ROOT
. We plan to enhance DAnCE in the next few months. We believe
DAnCE will replace existing tool sets in
$CIAO_ROOT/tools
. There are a few features in
$CIAO_ROOT/tools
that are missing in the DAnCE
implementation. Please see TODO file
for more details. We plan to implement them soon and use DAnCE
continuously.
- The first cut of DAnCE includes two parts:
-
A modeling tool chain ,
CoSMIC, which is capable of describing the Assembly/Component
using
GME as the development bed. The artifacts generated from the
CoSMIC are a set of XML descriptors.
- 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.
.
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 this.)
CIAO doesn't yet support features that help integrating CORBA
components with Enterprise Java Beans (EJB).
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.
