You can use the keyword
@HOSTNAME@ in your libnames.parm primary path or ROPTIONS= path to
substitute the short host name in the path. Path substitution is useful
when SPD Server is installed on a shared file system, accessible by
multiple hosts, in which each host is running its own image of SPD
Server. Path substitution enables each host to share the same libnames.parm
file, but substitutes the unique pathnames that each host requires.
LIBNAME host_specific= /data/@HOSTNAME@;
