Building a Stock Quoter with TAO

Running the application

Now that we have all the components and driver programs successfully built, along with the flattened_deploymentplan generated by PICML, we will be able to run our application

From different command prompts in %CIAO_ROOT%/docs/tutorials/Quoter/Simple/descriptors/ directory:

Start NodeManagers (NodeDameon) by running runNodeDaemon.pl
Start the execution manager %CIAO_ROOT%/DAnCE/ExecutionManager/Execution_Manager -o ior -i Stock.dat

The Stock.dat file describes the deployment daemons CIAO's Execution_Manager will contact to instantiate ComponentServer's, home's, and component instances. Each line specify the name of a installation "destination" and the corresponding IOR for the CIAO_Daemon.

NOTE: As one can see, we use the "Stock.dat" file to instruct the Execution_Manager how to find the endpoint of each individual NodeManager (i.e., Node Daemon) where component(s) will be deployed, so this is non-standard. We plan to use Naming Service to do this in the future.

Start the plan_launcher by running %CIAO_ROOT%/DAnCE/Plan_Launcher/Plan_Launcher -p flattened_deploymentplan.cdp -k file://ior
By now the components should be successfully deployed. You may run the driver program to start the application. e.g. you can try the following
