NAME

dcs - domain configuration server

SYNOPSIS

/usr/lib/dcs [ -s sessions ]

DESCRIPTION

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.

OPTIONS

-s sessions 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 used.

ERRORS

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.
