Common Parameters to MIDAS Utilities

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

Midas experiment (exptname)

The MIDAS utility input parameter exptname

[-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(i.e. single default experiment), both the exptname input parameter and environment variable MIDAS_EXPT_NAME will be superseded.

Midas host (hostname)

The MIDAS utility input parameter hostname

[-h <hostname> ]

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(i.e. single default experiment), both the hostname input parameter and environment variable MIDAS_SERVER_HOST will be superseded.
