10.1.2 Configuring Servers
Use the server create operation to make an application server accessible to the server
control facility. Configuring a server means creating the information needed to start and
control the server. Typically this includes a server’s starting command line and
arguments, along with other information needed to start DCE applications.
Some servers need to be available whenever a host system is running. For instance, you
might want a server that provides information on host activity to start at the host boot
time and run until the host shuts down. Other kinds of services might be needed or only
for brief periods. The server control facility has an administrative interface that lets you
specify some conditions for starting and stopping servers:
• Explicit: You can set a server so that you can explicitly start it whenever you want.
• Boot: You can set a server to start at boot time.
• Automatic: You can set a server to start on demand; that is, it starts whenever a
client request for its services is received at the host system.
• Failure: You can set a server to start automatically if it exits unexpectedly.
The following example creates an entry for a fictitious video clip server named
video_clip on the local host. For a remote host or a host in another cell, use the cell-
relative or the global name. The program name vclip invokes the server that is located in
the /usr/local/bin working directory. The server has a catalog mode that was set by
specifying -catalog as the argument. The server uses the DCE Security Service, so the
server has a principal name Vclip_Srv_1. The -entryname option specifies the entry
name in the Cell Directory Service (CDS) where the server stores its binding
information. The -starton option sets the server to start when dced receives an explicit
server start operation that names the video_clip server. The failure attribute further
specifies to restart the server if it exits with a status that is not successful. The -services
option has annotation information to help administrators identify servers when this
information is returned with server show operations. The interface attribute is needed
because the DCE daemon copies this information into the host endpoint map when the
server starts.
