22 which starts the dcm running in the proper working directory and
23 captures logging messages.
27 may be disabled by the presence of the file
29 or by setting the value of
31 to zero in the SMS database. Debug mode may be enabled in the dcm by
32 specifying an integer on the command line or by setting the
35 The command line value will override the environment variable. Three
36 bits are currently defined in the debug value: DBG_PLAIN = 01,
37 DBG_VERBOSE = 02, DBG_TRACE = 04. Logging is done to standard output.
38 If critical errors are detected, they are logged to
39 .B /u1/sms/critical.log
40 and in a zephyrgram to class
44 in addition to standard output.
49 must both be authorized to access each of the tables by RTI Ingres,

56 will for off generator programs of the form
57 .B /u1/sms/bin/\fIservice\fB.gen.
58 Each generator takes as an argument the name of the output file to
59 produce. Many of them also require working directories in
60 .B /u1/sms/dcm/\fIservice\fB.
61 A generator exits with a status code defined in
65 is a common exit status if the database hasn't changed since the last
66 time this generator was run.
69 sets its working directory to the root, disconnects from the terminal
70 and puts itself in the background. It then starts
72 and will capture lines the dcm writes to standard output and log them
75 along with a timestamp.
77 will also log the exit status of the
85 /u1/sms/dcm/locks/* \- empty files will be created here for advisory locks.
87 /u1/sms/bin/*.gen \- service file generators will be searched for
