dcs - domain configuration server
/usr/lib/dcs [ -s sessions ]
The domain configuration server (DCS) is a daemon process
that runs on Sun servers that support remote dynamic recon-
figuration (DR) clients. It is started by inetd(1M) when the
first DR request is received from a client connecting to the
network service sun-dr. After the DCS accepts a DR request,
it uses the libcfgadm(3LIB) interface to execute the DR
operation. After the operation is performed, the results are
returned to the client.
The DCS listens on the network service labeled sun-dr. Its
underlying protocol is TCP, and it is invoked as an inetd
server using the TCP transport. The entries for the DCS in
the /etc/inet/inetd.conf file are as follows:
sun-dr stream tcp wait root /usr/lib/dcs dcs
sun-dr stream tcp6 wait root /usr/lib/dcs dcs
These entries enable remote DR operations. Removing them
does not negatively impact the server; however, all DR
operations initiated from a remote host would fail.
Sets the number of active sessions that the DCS allows
at any one time. When the limit is reached, the DCS
stops accepting connections until active sessions com-
plete the execution of their DR operation. If this
option is not specified, a default value of 128 is
The DCS uses syslog(3C) to report status and error messages.
All of the messages are logged with the LOG_DAEMON facility.
Error messages are logged with the LOG_ERR and LOG_NOTICE
priorities, and informational messages are logged with the
LOG_INFO priority. The default entries in the
/etc/syslog.conf file log all of the DCS error messages to
the /var/adm/messages log.
