12[1mDESCRIPTION[0m
13       The  [1mlfc‐dli  [22mcommand  starts  the  LFC Data  Loca‐
14tion Interface server.
15       This    command    is    usually    executed   at   system
16startup   time
17       ([1m/etc/rc.local[22m).   This  will  create  a  pool   of
18threads, look for requests
19       and  pass  them  to  the LFC.  When  a  request  has  been
20completed,  the
21       thread becomes idle until it is allocated to  another  re‐
22quest.
23
24       All error messages and statistical information are kept in
25a log.
26
27       The Data Location Interface server listen port number  can
28be defined on
29       client  hosts  and  on  the server itself in either of the
30following ways:
31
32              setting an environment variable DLI_PORT
33
34                     setenv DLI_PORT 8085
35
36              an entry in [1m/etc/shift.conf [22mlike:
37
38                     DLI  PORT 8085
39
40       If none of these methods is used, the default port  number
41is taken from
42       the definition of DLI_PORT in dli_server.h.
43
44       In  the log each entry has a timestamp.  For each user re‐
45quest there is
46       one message giving information about the requestor  (host‐
47name)  and  one
48       message   DLI98   giving  the request itself.  The comple‐
49tion code of the
50       request is also logged.
