Virtual Frontend for FESA mockups

The virtual frontend vmla02 has been selected for testing the FESA software for the Cryring at an early stage.

To launch a FESA binary during the boot process consider the following steps:

• prepare an instantiation of the FESA class for the virtual FEC vmla02
• compile and deploy the FESA class
  • during deployment the start script is copied to /common/export/fesa/local/vmla02/scripts on the acc6 cluster, the direcory is mounted on the virtual FEC as /opt/fesa/local/scripts/
• to launch the FESA class automatically add the call of your start script to /common/export/fesa/local/vmla02/init/startthis. The script startthis will be executed during the boot process of the virtual FEC. An example for such a script is this:

    #!/bin/sh
    set -u
    set -e
  
    echo increase the original message queue size
    echo 32768 >> /proc/sys/fs/mqueue/msgsize_max
  
    echo launch BumperDU
    ./opt/fesa/local/scripts/start_BumperDU_M.sh &
  
    echo launch LinacHFDU
    ./opt/fesa/local/scripts/start_LinacHFDU_S.sh &

• log in as root on the virtual FEC
• reboot...
