User Level Mapping (UNIX and VMS)
Next higher in precedence are the individual user's mappings. Of the four levels, user-level mapping is probably the least frequently used; the combination of mappings at the other three levels suffices for most users.
To make the user-level mapping file known to the FRS, the user must execute the following command at the operating system level:
UNIX:
For the C shell:
setenv INGRES_KEYS full_pathname/file_name
For the Bourne shell:
INGRES_KEYS=full_pathname/file_name
export INGRES_KEYS
The parameter
full‑pathname/file_name is the full pathname and file name for the mapping file. To eliminate the need to invoke this command for each terminal session, you can include this command in the file .login (C shell) or .profile (Bourne shell).
VMS:
define INGRES_KEYS file_specification
The file_specification parameter is the full specification for the mapping file. To eliminate the need to invoke this command for each terminal session, you can include this command in the login.com file.
