IMCCONFIG environment variable

IMCCONFIG environment variable

The IMCCONFIG environment variable specifies a nondefault filename, and optionally a pathname, for the MaxConnect configuration file. On UNIX™ systems that support the C shell, this variable can be set by the following command.

setenvIMCCONFIGpathname

pathname: is a full pathname or a simple filename.

When the setting is a filename that is not qualified by a full pathname, MaxConnect searches for the specified file in the $INFORMIXDIR/etc/ directory. Thus, if you set IMCCONFIG to IMCconfig.imc2, MaxConnect searches for $INFORMIXDIR/etc/IMCconfig.imc2 as its configuration file.

If the IMCCONFIG environment variable is not set, MaxConnect searches by default for $INFORMIXDIR/etc/IMCconfig as its configuration file.
