The GT4 Integrated Practical

GT4 Advanced Practical Solutions

1. Downloading Solution for Advanced Practical

   You can download and install the solution for advanced practical as described here:

   cd /tmp/$USER/gt4-ap-client/ws-clients/src/org/globus/tutorial
   wget http://www.gs.unina.it/~gt4/advanced/gt4-ap-solution.tar.gz
   tar xvzf gt4-ap-solution.tar.gz
   

   You can look for the word ADD in the source files to look for the code that needed to be added to complete the exercise. Once you install these files, deploy the clients and try running the client as per instructions in the GT4 Advanced Tutorial page.

2. Running GT4 Advanced Practical against local server

   As a part of the introductory practical, you would have installed the relevant bits of the Globus Toolkit and used it deploy the advanced practical services and client. You can use that install to start up a local container and test the advanced practical. The steps requires are listed below:

   • Set GLOBUS_LOCATION to your local install.
   • cd $GLOBUS_LOCATION
   • mkdir fileStoreData
   • Now deploy the clients as described in the advanced practical instructions.
   • To start up container:

     cd $GLOBUS_LOCATION
     bin/globus-start-container -nosec
     

   • Now you can run the advanced practical as described in the document, but use localhost:8080 as the container to contact.
   • If you start container in a non default port (using -p option), then change the container contact information to use that port number.
