Arguments
The system framework code (mfe.c) has the following arguments:
[-h hostname ] : host name (see Common Parameters to MIDAS Utilities) [-e exptname ] : experiment name (see Common Parameters to MIDAS Utilities) [-D ] : Become a Daemon. [-O ] : Become a Daemon but keep stdout [-d ] : Used for debugging the frontend [-i index] : Set frontend index (used with Mevb . This argument has been introduced to : facilitate the multiple frontend configuration operation required for the Event Builder
Usage
Start the application as a daemon, using the default host, experiment and port :
e.g. fevme -D
Start the application superceding the default host, experiment and port:
e.g. fegpib -e exp218 -h isdaq10 -p 7077 -D
