Common Input Parameters

Each of the MIDAS utilities define a number of input parameters. The following parameters are common to many :

[-e <exptname> ] 
specifies the MIDAS Experiment to connect to (where multiple experiments are defined on the MIDAS host (see exptab).
  • This option supersedes the default experiment name given by the environment variable MIDAS_EXPT_NAME , if defined.
  • If multiple experiments are defined, unless MIDAS_EXPT_NAME is defined or this argument is supplied, the application will request the experiment name.
  • If the environment variable MIDAS_DIR is defined (i.e. single default experiment), both the exptname input parameter and environment variable MIDAS_EXPT_NAME will be superseded.


[-h <hostname> ]  
connect to midas server mserver on given host hostname, i.e. specifies the MIDAS Host to connect to when connecting to an experiment running on a remote host. If the experiment is running on the local host, this argument need not be supplied.
  • If hostname is supplied :
    • hostname must be a valid IP host name.
    • hostname supersedes the default hostname given by the environment variable MIDAS_SERVER_HOST , if defined.
    • the mserver utility must be running on the remote host.
  • If more than one copy of mserver is running, the mserver portname must be specified, e.g.
odbedit -h myhost:1173 -e myexpt -c "ls /Experiment"


  • If the environment variable MIDAS_DIR is defined (i.e. single default experiment), both the hostname input parameter and environment variable MIDAS_SERVER_HOST will be superseded.
