By default, when you run MFDAS from the command line it uses the server, node, and port most recently specified in the mfa_config.json file. However, you can specify different settings to be used by the MFDAS command line by setting the MFA_SERVER_PARMS environment variable before running mfdas.exe. The format of this environment variable is as follows:
EXPORT MFA_SERVER_PARMS=MFSRV:name,MFNODE:node,MFPORT:portnum
where:
EXPORT MFA_SERVER_PARMS=MFSRV:MVSSRV,MFNODE:MVS.SERVER.COM,MFPORT:6000
