IMCSERVER environment variable

The IMCSERVER environment variable specifies the name of a database server entry in the sqlhosts file that contains information about connectivity.

The database server can be either local or remote. On UNIX™ systems that support the C shell, the IMCSERVER environment variable can be set by the command.
