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

  1. 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.

  2. The first cut of DAnCE includes two parts: 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.)

  3. CIAO doesn't yet support features that help integrating CORBA components with Enterprise Java Beans (EJB).

  4. 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.
