4 dcm, startdcm \- build config files from Moira database and update servers
13 must be run periodically on the Moira server. It is usually run every
16 daemon. Rather than invoke
20 which starts the dcm running in the proper working directory and
21 captures logging messages.
25 may be disabled by the presence of the file
27 or by setting the value of
29 to zero in the Moira database. Debug mode may be enabled in the dcm by
30 specifying an integer on the command line or by setting the
33 The command line value will override the environment variable. Three
34 bits are currently defined in the debug value: DBG_PLAIN = 01,
35 DBG_VERBOSE = 02, DBG_TRACE = 04. Logging is done to standard output.
36 If critical errors are detected, they are logged to
37 .B /u1/sms/critical.log
38 and in a zephyrgram to class
42 in addition to standard output.
47 must both be authorized to access each of the tables by RTI Ingres,

52 For the actual generation of config files, the
54 will fork off generator programs of the form
55 .B /u1/sms/bin/\fIservice\fB.gen.
56 Each generator takes as an argument the name of the output file to
57 produce. Many of them also require working directories in
58 .B /u1/sms/dcm/\fIservice\fB.
59 A generator exits with a status code defined in
63 is a common exit status if the database hasn't changed since the last
64 time this generator was run.
67 sets its working directory to the root, disconnects from the terminal
68 and puts itself in the background. It then starts
70 and will capture lines the dcm writes to standard output and log them
73 along with a timestamp.
75 will also log the exit status of the
83 /u1/sms/dcm/locks/* \- empty files will be created here for advisory locks.
85 /u1/sms/bin/*.gen \- service file generators will be searched for
88 /tmp/tkt_dcm \- temporary Kerberos ticket storage.
90 /etc/srvtab \- The dcm must be able to get Kerberos tickets for "sms"
